How to Make Reese's Pieces Peanut Butter Blondies
-
Preheat your oven to 350°F (175°C). Prepare a 9x13 baking pan by greasing it with cooking spray or lining it with parchment paper for easy removal.
-
Cream together the softened butter and brown sugar in a large bowl. Beat them together until the mixture becomes light and fluffy, which should take about 2-3 minutes.
-
Mix in the peanut butter until it's well combined. The creamy texture of the peanut butter should blend seamlessly with your buttery mixture, creating a delightful aroma.
-
Add the eggs and vanilla extract, stirring until everything is fully incorporated. This step is crucial for binding your blondies together, giving them that perfect chewy texture!
-
Combine the all-purpose flour, baking powder, and salt in a separate bowl. Gradually mix this dry mixture into the wet batter until just combined; be careful not to over-mix!
-
Fold in the Reese's Pieces gently until they are evenly distributed throughout the batter. This will ensure that every bite is packed with their delightful crunch and peanut butter flavor.
-
Spread the batter into the prepared baking pan. Use a rubber spatula to smooth it out evenly, making sure it reaches the edges of the pan.
-
Bake for about 30 minutes, or until a toothpick inserted into the center comes out clean, with just a few moist crumbs attached. Your kitchen will start to smell heavenly!
-
Cool the blondies for about 10 minutes in the pan before transferring them to a wire rack. Cut them into bars once they’ve cooled slightly, and then serve!
Optional: Drizzle with melted chocolate for an extra indulgent touch.

Expert Tips for Reese's Pieces Peanut Butter Blondies
- Butter Magic: Use softened butter rather than melted to ensure a creamy texture that blends smoothly without oily spots.
- Mix with Care: Over-mixing after adding flour can lead to tough blondies; mix until just combined for that perfect chewy bite.
- Pan Size Matters: If you're using an 8x8 pan, remember to halve the recipe to avoid overly thick blondies that may not bake evenly.
- Fresh Ingredients: Check that your baking powder is fresh; stale baking powder can result in blondies that don’t rise properly, affecting your results.
- Storage Savvy: Keep them in an airtight container at room temperature to maintain freshness for up to 5 days—perfect for snacking!
- Custom Flavor: Feel free to swap in your favorite mix-ins, but keep the Reese's Pieces for those delightful bursts of peanut butter flavor.
Make Ahead Options
These Reese's Pieces Peanut Butter Blondies are perfect for meal prep enthusiasts! You can prepare the blondie batter up to 24 hours in advance, storing it in the refrigerator in an airtight container to maintain its freshness. To do this, follow the recipe instructions up to the point of spreading the batter into the baking pan. When you're ready to bake, simply spread the batter into the prepared pan and allow it to sit at room temperature for about 15 minutes before popping it in the oven for about 30 minutes. This way, you'll enjoy soft, chewy blondies that taste just as delicious, without sacrificing quality on busy weeknights!

Reese's Pieces Peanut Butter Blondies Recipe FAQs
How do I select the right peanut butter for these blondies?
Absolutely! For the best results, choose a creamy peanut butter that mixes well—look for one without added sugar or oils. Natural peanut butter will give a more authentic taste, while processed options can add a smoother texture. I often use a well-known brand for consistency.
How long do the blondies last in storage?
Very! If you store the blondies in an airtight container at room temperature, they will maintain their chewiness for up to 5 days. If you want to keep them fresh longer, you can refrigerate them, extending their shelf life to about a week. Just be sure to let them warm up to room temperature for the best flavor!
Can I freeze Reese's Pieces Peanut Butter Blondies?
Absolutely! To freeze, wrap each blondie in plastic wrap, then cover them with foil to prevent freezer burn. Place the wrapped blondies in a freezer-safe zip-top bag. They can be frozen for up to 3 months. When you’re ready to enjoy, thaw them in the refrigerator overnight, and then pop them in the microwave for a few seconds to warm them up.
What can I do if my blondies turn out too dry or crumbly?
This can happen if the batter is over-mixed or baked for too long. If your blondies are dry, next time, ensure you mix the flour in gently—just until combined. Also, keep a close eye on the baking time; remove them from the oven as soon as a toothpick comes out with a few moist crumbs attached.
Are there any allergy considerations I should keep in mind?
Very much so! Since this recipe contains peanut butter, those with peanut allergies should definitely avoid it. You could experiment with sunflower seed butter as an alternative for a nut-free option. Also, double-check that any chocolate additions or substitutes (like chocolate chips) are allergy-friendly, as some brands may have cross-contamination with nuts.
Can I use chocolate chips instead of Reese's Pieces?
Absolutely! If you prefer a chocolatey twist, substitute the Reese's Pieces with a cup of chocolate chips. This not only maintains the delightful chewy texture but adds a rich chocolate flavor that pairs beautifully with the peanut butter. Just remember to enjoy the delightful crunch that Reese's Pieces bring!
