Step‑by‑Step Instructions for Reese's Brownies Peanut Butter
Step 1: Preheat and Prepare Your Pan
Begin your baking journey by preheating your oven to 350°F. While the oven heats, take an 8x8-inch baking pan and line it with parchment paper, or generously coat it with cooking spray. This ensures that your gooey Reese's Brownies Peanut Butter will release easily, making for clean, perfect squares once they're baked.
Step 2: Mix the Brownie Batter
In a large mixing bowl, combine 2 cups of white sugar, 1 ½ cups of all-purpose flour, 1 cup of melted butter, 4 large eggs, ½ cup of cocoa powder, 1 teaspoon of vanilla extract, ½ teaspoon of baking powder, and ½ teaspoon of salt. Using a hand mixer or a whisk, beat the mixture until it turns smooth and creamy, with no lumps in sight. This rich batter is the heart of your brownies!
Step 3: Layer Your Batter
Carefully pour half of the velvety brownie batter into your prepared pan, spreading it evenly with a spatula. This will serve as the base for your scrumptious Reese's Brownies Peanut Butter. Make sure that the layer is consistent to ensure even baking and a perfect bite every time!
Step 4: Add the Reese's Goodies
Sprinkle one bag of Reese's Baking Cups and a handful of Reese's Pieces candy over the batter in the pan. This is where the magic happens; the chocolate and peanut butter flavors will meld beautifully as they bake. Be sure to distribute them evenly to guarantee that each square is packed with delightful surprises.
Step 5: Top It Off
Pour the remaining brownie batter over the top of the Reese's layer, spreading it smoothly to cover the candies completely. This sealing step is crucial to keep those delicious morsels hidden until you take that first bite of your Reese's Brownies Peanut Butter.
Step 6: Add More Reese's
Open your additional bag of Reese's and sprinkle the candies over the top of the brownie batter. Gently press them in to ensure they meld into the surface as they bake, adding an extra layer of flavor and appeal. These will give your brownies a delicious pop of color and texture.
Step 7: Bake to Perfection
Place your baking pan into the preheated oven and bake the brownies for 55-65 minutes. Keep an eye on them; they’re done when the edges pull away slightly from the pan and a toothpick inserted in the center comes out clean or with just a few moist crumbs clinging to it.
Step 8: Cool and Slice
Once baked, remove the pan from the oven and let the brownies cool completely in the pan. Patience is key here, as cooling allows the flavors to settle. Once cool, use the parchment paper to lift the brownies out, place them on a cutting board, and slice into dreamy squares to share with friends and family.

Make Ahead Options
These Reese's Brownies Peanut Butter are a game-changer for meal prep enthusiasts! You can mix the brownie batter and store it in the refrigerator for up to 24 hours before baking, keeping the flavors fresh and preventing any browning. Additionally, you can also prepare the layers by adding the Reese's Baking Cups and Pieces, then cover with plastic wrap to refrigerate until you're ready to bake. When you're ready to indulge, simply pour the prepared batter into your pan and bake as directed. This way, you can enjoy the rich, decadent goodness with minimal effort on busy weeknights!

What should I do if my brownies are too dry?
Very likely, your brownies could have been overbaked. For perfect fudginess, you should remove them from the oven as soon as a toothpick comes out with a few moist crumbs. If you've already baked them too long, consider serving with a scoop of ice cream to complement the texture. If you find them too dry next time, try covering the pan with foil during the last 10-15 minutes of baking to retain moisture.
Are there any dietary considerations I should keep in mind for Reese's Brownies?
Great question! These brownies contain gluten and dairy, as they are made with flour and butter. If you’re looking for alternatives, swapping all-purpose flour with a gluten-free blend and using dairy-free butter can work quite well.
