  • Baking Powder – A leavening agent to help blondies rise; no direct substitute, but baking soda may work with adjustments.

  • Unsalted Butter – Adds moisture and richness; substitution: coconut oil for a dairy-free option.
  • Light Brown Sugar – Contributes moisture and a rich caramel flavor; can use dark brown sugar for a deeper flavor.
  • Granulated White Sugar – Provides sweetness and texture; omit for lower sugar content or substitute with a sugar alternative.
  • Smooth Peanut Butter – Flavor base providing creaminess; substitution: almond butter or sunbutter for nut-free versions.
  • Large Eggs – Binds ingredients and adds moisture; substitution: flax eggs for a vegan option (1 tbsp flaxseed meal + 2.5 tbsp water).
  • Vanilla Extract – Enhances overall flavor; omit only if necessary, or use a different extract (almond) for a unique twist.

Step‑by‑Step Instructions for Reese’s Peanut Butter Blondies

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 13×9-inch baking pan by lining it with foil or parchment paper, leaving a bit of overhang on the sides for easy removal later. Lightly grease the lining to ensure your Reese’s Peanut Butter Blondies come out effortlessly after baking.

Step 2: Combine the Dry Ingredients
In a medium-sized mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of salt. This blend will provide the structure and rise needed for your blondies. Make sure there are no lumps, and set the bowl aside while you move on to the wet ingredients.

Step 3: Mix the Wet Ingredients
In a separate large bowl, melt ½ cup of unsalted butter, allowing it to cool slightly. Next, add in 1 cup of light brown sugar, ½ cup of granulated sugar, 2 large eggs, 1 teaspoon of vanilla extract, and 1 cup of smooth peanut butter. Use a hand mixer or whisk to blend the mixture until it is creamy and fully combined, creating a rich flavor base for your blondies.

Step 4: Combine Wet and Dry Mixtures
Gradually fold the dry ingredient mixture into the wet mixture using a spatula, mixing just until combined. Be careful not to overmix; the batter should be slightly lumpy. This step ensures that your Reese’s Peanut Butter Blondies maintain their chewy texture, so keep an eye on it and stop mixing as soon as no flour is visible.

Step 5: Add Chocolate and Candy Pieces
Gently fold in 1 cup of semi-sweet chocolate chips and 1 cup of Reese’s Pieces until evenly distributed throughout the batter. The chocolate will melt beautifully while baking, complementing the peanut butter flavor. Transfer the thick batter into the prepared pan, spreading it evenly to ensure even baking.

Step 6: Bake the Blondies
Place the pan in the preheated oven and bake for 22-25 minutes. Keep an eye on them; the top should be shiny and lightly golden, and a toothpick inserted into the center may come out with a few moist crumbs. Remember, they may look slightly underbaked—this is ideal for that gooey texture!

Step 7: Cool and Cut
Remove the blondies from the oven and let them cool in the pan for at least 10 minutes. Once slightly cooled, use the overhanging foil or parchment to lift the entire batch out onto a cutting board. Allow them to cool completely before cutting into bars, ensuring you achieve those perfect, chewy slices of Reese’s Peanut Butter Blondies.

Make Ahead Options

These delectable Reese’s Peanut Butter Blondies are perfect for meal prep, saving you time on busy days! You can prepare the batter up to 24 hours in advance and refrigerate it. Simply mix the dry ingredients in one bowl and the wet ingredients in another, then combine them before placing the batter into the baking pan. When ready to bake, just preheat your oven and bake as directed. This method maintains the blondies’ rich flavors and texture—just as delicious as if they were made fresh! Try this prep-in-advance approach, and enjoy perfectly fudgy blondies with minimal effort when you’re ready to impress family and friends!

How to Store and Freeze Reese’s Peanut Butter Blondies

Room Temperature: Store your blondies covered at room temperature for up to 5 days. This keeps them fresh and soft for endless snacking!

Fridge: For longer freshness, keep them in an airtight container in the fridge for up to 1 week. Just remember to let them come to room temperature before enjoying!

Freezer: You can freeze the blondies for up to 3 months. Wrap them tightly in plastic wrap or foil and place them in a freezer-safe bag. Thaw at room temperature or warm them slightly in the microwave for a delicious treat.

Reese’s Peanut Butter Blondies Variations

Feel free to unleash your creativity and make these blondies uniquely yours! The delightful aromas and textures invite wonderful customization options.

  • Nut-Free: Replace smooth peanut butter with sunflower seed butter for a delicious nut-free alternative. The richness of sunflower seed butter creates a similar creamy texture that pairs beautifully with chocolate.

  • Dairy-Free: Swap unsalted butter for coconut oil to make these blondies dairy-free! You’ll still enjoy that luscious texture without any dairy, making them suitable for various dietary preferences.

  • Sugar Alternative: Use coconut sugar or a sugar substitute for a healthier option. This substitution gives a slightly different flavor but maintains the sweetness that makes these blondies irresistible.

  • Spiced Up: Add a teaspoon of cinnamon or a pinch of cayenne pepper for a warm twist with an unexpected kick. It’s a delightful way to elevate the flavors while adding a touch of warmth to every bite!

  • Mix-in Madness: Replace Reese’s Pieces with M&M’s, chopped nuts, or dried fruit for a fun flavor explosion. This simple swap not only enhances the texture but also adds a burst of color to your blondies.

  • Gooey Goodness: For the extra indulgence, top your blondies with a quick chocolate ganache. Melt chocolate with a dash of cream, pour it over the cooled blondies, and let it set for a truly decadent treat.

  • Frozen Treat: Try freezing scoops of Cookie Dough Ice Cream right in the blondie batter before baking. The result is a delightful frozen surprise that will have everyone talking!

  • Salted Caramel Bliss: Drizzle some salted caramel sauce on top after baking for a sweet and salty combo that intermingles beautifully with the peanut butter. This little touch can elevate the experience to new heights!

Expert Tips for Reese’s Peanut Butter Blondies

Watch the Bake Time: Keep a close eye on baking, as blondies can quickly turn from gooey to dry. Aim for a shiny, slightly golden top.

Choose the Right Peanut Butter: For best texture, use a creamy, non-natural peanut butter. All-natural versions may lead to oily blondies and less creaminess.

Avoid Overmixing: Once you combine the wet and dry ingredients, mix gently until just combined. Overmixing can make your blondies tough instead of chewy.

Cooling is Key: Allow the blondies to cool completely in the pan before cutting. This step ensures they firm up for that perfect chewy texture.

Experiment with Mix-ins: Don’t hesitate to swap in different mix-ins like chopped nuts or butterscotch chips. Let your creativity shine with your Reese’s Peanut Butter Blondies!

Reese’s Peanut Butter Blondies Recipe FAQs

How should I choose the right peanut butter for my blondies?
Absolutely! For these Reese’s Peanut Butter Blondies, I recommend using a creamy, non-natural peanut butter. Natural peanut butter can often be too oily, which might lead to a less desirable texture. Look for brands that have added stabilizers for the best results.

What is the best way to store leftover blondies?
Very! You can store your blondies covered at room temperature for up to 5 days to maintain their soft and chewy texture. For longer-lasting freshness, keep them in an airtight container in the fridge for up to 1 week. Just let them come to room temperature before enjoying for the best flavor!

Can I freeze Reese’s Peanut Butter Blondies?
Absolutely! You can freeze these blondies for up to 3 months for a quick treat later on. Simply wrap them tightly in plastic wrap or foil, then place them in a freezer-safe bag. When you’re ready to enjoy them, thaw at room temperature, or warm them slightly in the microwave for a gooey moment of bliss!

My blondies came out too dry. What did I do wrong?
Oh dear! Dry blondies can sometimes result from overbaking. It’s key to keep a close watch on them and aim for a shiny, slightly golden top around the 22-25 minute mark. If your toothpick comes out with a few moist crumbs, that’s perfect! They may look underbaked, but they will continue to firm up while cooling.

Are there any dietary considerations for making these blondies?
Very much so! If you’re looking for a nut-free version, you can substitute smooth peanut butter with sunbutter or almond butter. Additionally, for a vegan option, swap the eggs with flax eggs—mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water and allow it to sit for a few minutes. This will help bind your ingredients just like eggs do!

Can I use different mix-ins in my blondies?
Absolutely! The more the merrier! You can customize your blondies by swapping out Reese’s Pieces for M&M’s or even chopped nuts. Adding a layer of chocolate ganache on top after they cool can elevate the experience, giving you another reason to indulge!
