Peanut butter: The star of the show, peanut butter infuses these blondies with its signature rich, earthy, and nutty flavor. Using creamy peanut butter is highly recommended for a smooth and consistent texture throughout the blondie, ensuring that delicious peanut butter taste is in every bite.

Melted butter: Beyond just providing a luscious, buttery taste, melted butter is essential for moisture, helping to create that wonderfully soft and chewy texture characteristic of perfect blondies. It also helps bind the ingredients together, contributing to the overall structure.

Brown sugar: More than just a sweetener, brown sugar plays a pivotal role in developing the deep, complex flavor profile of these blondies. Its molasses content adds a distinctive hint of caramel and ensures a moist, tender crumb, which is crucial for achieving that desirable chewy texture.

All-purpose flour: This foundational ingredient provides the necessary structure and body for the blondie batter. It ensures the blondies hold their shape while remaining tender, preventing them from becoming too cakey or crumbly. The right amount of flour creates the perfect balance.

Vanilla extract: A touch of vanilla extract elevates and rounds out the overall flavor profile of the blondies. Its sweet, aromatic notes complement the rich peanut butter and brown sugar, adding depth and warmth to the dessert.

Baking powder: As a leavening agent, baking powder helps the blondies rise just enough to achieve a slightly light and airy interior without sacrificing their signature density and chewiness. It ensures a pleasant texture that isn’t overly flat or heavy.

Salt: A pinch of salt is vital for balancing the sweetness of the sugar and enhancing the rich flavors of the peanut butter and butter. It helps to bring out the best in all the other ingredients, preventing the blondies from tasting one-dimensionally sweet.

Eggs: Eggs serve multiple purposes in this recipe: they act as a crucial binding agent, holding all the ingredients together; they add richness and moisture; and they contribute to the blondies’ overall structure and slightly chewy texture, ensuring a cohesive and satisfying treat.

Achieving the perfect texture for these chewy Peanut Butter Blondies hinges significantly on the initial blending of your wet ingredients. When combining the melted butter and peanut butter, it is paramount that both ingredients are at a similar temperature. If the melted butter is hot and the peanut butter is cold, or vice versa, they are more likely to separate or clump, resulting in an uneven batter. A smooth, emulsified mixture at this stage is absolutely crucial for the overall consistency and ultimate chewiness of your finished blondies. Consider briefly warming the peanut butter in the microwave for a few seconds if it’s too firm, ensuring it’s closer to the temperature of your melted butter.

Furthermore, when you incorporate the brown sugar into this butter-peanut butter mixture, dedicate enough time to mix it thoroughly until it is completely dissolved. Undissolved brown sugar granules can lead to a grainy or gritty texture in the final baked product, detracting from the desired smooth and tender bite. Continue to whisk or beat the mixture until it appears homogeneous and glossy. This attention to detail in the early stages of mixing will pay off immensely, guaranteeing a batch of blondies that are perfectly smooth, rich, and wonderfully chewy, just as they should be.

• Peanut butter – Substitute with almond butter: For those with peanut allergies or simply seeking a different flavor profile, almond butter is an excellent alternative. It offers a similar creamy texture and rich, nutty flavor, albeit with its own distinct, slightly milder taste, which can provide a lovely variation to your blondies.

• Peanut butter – Substitute with sunflower seed butter: A fantastic nut-free option, sunflower seed butter, often known as SunButter, closely mimics the consistency and taste of peanut butter. It’s perfect for school lunches or gatherings where nut allergies are a concern, offering a safe yet delicious alternative without compromising on the blondie’s character.

• Melted butter – Substitute with coconut oil: If you’re looking for a dairy-free option or want to introduce a subtle tropical note, coconut oil is a great choice. It has a similar fat content and moisture level to butter, ensuring your blondies remain moist and chewy, with a hint of coconut flavor that pairs surprisingly well with peanut butter.

• Melted butter – Substitute with margarine: For a dairy-free or reduced-fat option, margarine can be used as a direct 1:1 replacement for butter. It provides a comparable texture and moisture to the blondies, making it a reliable substitute without significant alteration to the overall outcome.

• Brown sugar – Substitute with coconut sugar: For a natural, unrefined sweetener with a slightly lower glycemic index, coconut sugar works beautifully. It offers a similar caramel-like flavor to brown sugar and contributes to the moistness, making it a healthier alternative without sacrificing taste or texture.

• Brown sugar – Substitute with white sugar and molasses: If you’re out of brown sugar, you can easily create your own. Mix a cup of white granulated sugar with one tablespoon of molasses. This combination effectively replicates the unique moisture, subtle caramel notes, and depth of flavor that brown sugar brings to the blondies.

• All-purpose flour – Substitute with gluten-free flour blend: To make these blondies suitable for individuals with gluten intolerance or celiac disease, a high-quality gluten-free flour blend (one that contains xanthan gum) can be used. Ensure it’s a blend designed for baking to achieve the best possible texture, which should remain chewy and delicious.

• All-purpose flour – Substitute with whole wheat flour: For a slightly healthier and heartier option, whole wheat flour can replace all-purpose flour. It adds a pleasant, subtle nutty flavor and increases the fiber content, though it may result in blondies that are a bit denser and have a slightly different texture.

• Vanilla extract – Substitute with almond extract: If you enjoy the distinct taste of almond, substituting vanilla extract with almond extract can provide a wonderful and different yet complementary flavor profile. Use it sparingly, as almond extract is more potent than vanilla.

• Vanilla extract – Substitute with maple syrup: For a unique twist, maple syrup can lend a distinctive sweetness and depth of flavor, adding warm, woody notes that pair well with the peanut butter. Adjust other liquid ingredients slightly if using a significant amount of maple syrup.

• Baking powder – Substitute with baking soda and cream of tartar: If you’re out of baking powder, you can create your own by mixing ¼ teaspoon of baking soda with ½ teaspoon of cream of tartar for every teaspoon of baking powder required. This combination effectively replicates the leavening effect, ensuring your blondies rise properly.

• Baking powder – Substitute with self-rising flour: If using self-rising flour instead of all-purpose flour, you will need to adjust the recipe by omitting the baking powder and salt, as self-rising flour already contains these leavening agents. This can simplify the dry ingredient mixing step.

• Salt – Substitute with sea salt: Sea salt can be used in the same amount as regular table salt. While it provides a similar level of saltiness, some bakers believe it offers a slightly cleaner taste and a trace of different mineral content, which can subtly enhance the overall flavor profile of your blondies.

• Salt – Substitute with kosher salt: When substituting kosher salt for fine table salt, it’s important to remember that kosher salt has larger, flakier crystals. Therefore, to achieve the same level of saltiness, you’ll need to use approximately 1.5 times the amount specified for table salt.

• Eggs – Substitute with flax eggs: For a vegan-friendly option, flax eggs are an excellent binder. To make one flax egg, mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit for 5-10 minutes until it forms a gel-like consistency. This effectively replaces chicken eggs in baking, ensuring moisture and structure.

• Eggs – Substitute with applesauce: Applesauce can act as both a binding agent and a source of moisture in baking. For each egg, substitute ¼ cup of unsweetened applesauce. While it may slightly alter the flavor of the blondies by adding a fruity note, it’s a popular choice for reducing fat and calories while maintaining tenderness.

• Storing Guidelines:

  • To prevent any unwelcome sogginess, always ensure your peanut butter blondies have cooled completely to room temperature before attempting to store them. This crucial step prevents condensation from forming inside the container.
  • Once cooled, carefully cut the blondies into your desired individual squares. Arrange them in an airtight container, using layers of parchment paper between stacked blondies to prevent sticking and preserve their pristine appearance.
  • For optimal freshness and taste, store the container at room temperature for up to 3 days. If you wish to extend their shelf life, transfer them to the refrigerator, where they will remain fresh and delicious for up to a full week.
  • For an extra layer of protection and to maintain maximum moisture, consider wrapping each individual blondie square tightly in plastic wrap before placing them in the airtight container. This helps seal in their flavor and prevents them from drying out.

• Freezing Guidelines:

  • Just like with storing, allow your baked blondies to cool completely before cutting them into squares. This ensures they firm up and are easier to handle for freezing.
  • Wrap each individual blondie square tightly in plastic wrap, making sure to remove as much air as possible. This step is essential to prevent freezer burn, which can compromise both the texture and flavor of your frozen treats.
  • Once wrapped, place the individual squares into a sturdy freezer-safe bag or an airtight container. Don’t forget to label the bag or container with the date you froze them, which will help you keep track of their freshness.
  • Properly stored, these blondies can be kept in the freezer for up to 3 months, ready to be enjoyed whenever a craving strikes.
  • When you’re ready to indulge, simply thaw the blondies at room temperature for a few hours, or transfer them to the refrigerator overnight. For a wonderfully warm, soft, and gooey treat, you can microwave a thawed blondie for just a few seconds (10-15 seconds usually suffices) before enjoying.

• Oven Method: For a gentle and even reheat that restores their fresh-baked chewiness, the oven is an excellent choice.

  1. Preheat your oven to a moderate 300°F (150°C). This low temperature prevents over-drying.
  2. Arrange the peanut butter blondies in a single layer on a baking sheet. For easy cleanup and to prevent sticking, line the sheet with parchment paper.
  3. To keep them from drying out and to maintain their delightful moisture, cover the blondies loosely with aluminum foil.
  4. Heat for approximately 10-15 minutes, or until the blondies are thoroughly warmed through to your liking.
  5. Carefully remove them from the oven and allow them to cool slightly for a minute or two before savoring each warm, tender bite.

• Microwave Method: When you need a quick and convenient warm-up, the microwave is your fastest option for a soft, gooey center.

  1. Place a single peanut butter blondie on a microwave-safe plate. Avoid overcrowding, as this can lead to uneven heating.
  2. For added moisture and to prevent the blondie from becoming tough, cover it with a slightly damp paper towel.
  3. Microwave on medium power for an initial burst of 20-30 seconds. Microwaves can vary, so start low.
  4. Check the blondie’s warmth by gently pressing it. If it’s not quite warm enough, heat for an additional 10 seconds, being careful not to overcook.
  5. Let it stand for a brief moment before indulging in its warm, soft goodness.

• Toaster Oven Method: Perfect for smaller batches or individual servings, a toaster oven offers similar results to a conventional oven.

  1. Preheat your toaster oven to 300°F (150°C).
  2. Carefully place the peanut butter blondies on a small, oven-safe baking tray, ensuring they have a little space around them.
  3. Just like with a regular oven, cover them loosely with aluminum foil to protect against drying out and preserve their tender texture.
  4. Heat for about 10 minutes, or until you feel they are adequately warmed through.
  5. Allow them to cool slightly on the tray before serving and enjoying.

• Steaming Method: This unconventional method is excellent for reheating, ensuring maximum moisture and a wonderfully soft texture, almost like they were just baked.

  1. Set up a steamer basket in a pot with a small amount of water, ensuring the water doesn’t touch the basket. Bring the water to a gentle boil, creating a consistent steam.
  2. Place the peanut butter blondies on a heatproof plate that fits inside your steamer. Cover the plate with a lid or aluminum foil to trap the steam effectively.
  3. Steam for approximately 5-7 minutes. The gentle steam will rehydrate and warm them beautifully without drying.
  4. Using oven mitts, carefully remove the hot plate and let the blondies cool for a moment or two before enjoying their incredibly moist texture.

• Air Fryer Method: For a slightly crisper exterior and a soft interior, the air fryer can be a surprisingly effective way to reheat blondies.

  1. Preheat your air fryer to 300°F (150°C).
  2. Place the peanut butter blondies in the air fryer basket in a single layer, making sure they do not overlap to allow for even airflow.
  3. Heat for about 5-7 minutes. Keep an eye on them, as air fryers can heat quickly.
  4. Check for warmth and desired crispness. If needed, you can heat for an additional 2-3 minutes, but be cautious of burning.
  5. Let them cool slightly on a rack before serving, allowing the exterior to firm up just a touch.

• Oven: The most fundamental tool, your oven is where the magic happens. It bakes the blondies evenly at the specified temperature of 350°F (175°C), transforming the raw batter into chewy, golden perfection. Ensure it’s preheated properly for consistent results.

• Baking pan: A sturdy 8×8 or 9×9 inch baking pan is essential. This container is where the blondie batter is spread, allowing it to bake into a perfectly uniform thickness. A metal pan often yields the best results for crispier edges and a soft interior.

• Mixing bowl: You’ll need at least one large mixing bowl, or preferably two if you’re following the dry and wet ingredient separation method. This bowl is used to combine and thoroughly mix all your ingredients, ensuring a homogenous batter.

• Whisk: A good quality whisk is invaluable for thoroughly combining dry ingredients like flour, baking powder, and salt, removing any lumps and ensuring they are evenly distributed before being added to the wet mixture.

• Spatula: A flexible rubber or silicone spatula is incredibly handy for scraping down the sides of the mixing bowl, ensuring all ingredients are incorporated. It’s also perfect for spreading the thick blondie batter evenly into the prepared baking pan.

• Measuring cups: Accuracy is key in baking. A set of dry measuring cups is essential for precisely measuring larger quantities of ingredients such as peanut butter, melted butter, brown sugar, and flour, ensuring the correct ratios for the perfect blondie consistency.

• Measuring spoons: For smaller quantities of powerful flavorings and leavening agents, a set of measuring spoons is indispensable. These are used to accurately measure ingredients like vanilla extract, baking powder, and salt, which can significantly impact the final taste and texture.

• Electric mixer: While not strictly necessary, an electric mixer (either handheld or stand mixer) can significantly ease the effort of beating the eggs until light and fluffy and ensuring the wet ingredients are smoothly and thoroughly combined, contributing to a lighter batter.

• Toothpick: The simplest yet most effective tool for determining doneness. By inserting a toothpick into the center of the blondies, you can easily check if they are baked through – it should come out clean, perhaps with a few moist crumbs attached, but no wet batter.

• Cooling rack: After baking, transferring the blondies (in their pan or carefully removed) to a cooling rack is important. This allows air to circulate underneath, preventing the bottom from becoming soggy and ensuring they cool evenly before cutting.

• Non-stick spray: To guarantee easy removal of your baked blondies and minimize cleanup, a good quality non-stick spray is invaluable. Liberally grease the baking pan before adding the batter to prevent any sticking, or line it with parchment paper.

Pre-measure ingredients: Adopt the “mise en place” philosophy by measuring out all your ingredients—wet and dry—before you even begin mixing. This eliminates frantic searching and measuring mid-recipe, significantly streamlining the entire baking process and reducing errors.

Use a microwave: Speed up the preparation of your wet ingredients. Soften the peanut butter and melt the butter in the microwave for quick and effortless mixing. Just be careful not to overheat the butter to avoid scorching, and ensure both are at a similar temperature for easy combining.

One-bowl method: Minimize cleanup and maximize efficiency by combining all your wet ingredients, then gradually adding the dry ingredients, all within the same mixing bowl. This reduces the number of dishes you’ll have to wash, saving precious time after baking.

Line the pan: A simple trick that makes a huge difference: always use parchment paper to line your baking pan, leaving an overhang on two sides. This allows for incredibly easy removal of the baked blondies and virtually eliminates sticky residue, simplifying cleanup significantly.

Cool quickly: If you’re in a hurry to cut your blondies, you don’t have to wait hours for them to cool on the counter. Once they’ve cooled slightly out of the oven, carefully transfer the entire pan to the fridge or freezer to cool faster before cutting into perfect squares. This helps them set and makes slicing much cleaner.
