Step‑by‑Step Instructions for Chewy REESE’S PIECES Peanut Butter Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures the perfect baking temperature for your Chewy REESE’S PIECES Peanut Butter Brownies. While the oven heats up, gather your ingredients and line an 11×13-inch baking pan with parchment paper, allowing some overhang for easy removal later.
Step 2: Mix the Butters
In a large mixing bowl, combine the melted unsalted butter and peanut butter, stirring until smooth and well-blended. Add both granulated sugar and light brown sugar to the mixture, and whisk vigorously for about 2 minutes until everything is combined. The mixture should be glossy and creamy, which will enhance the rich flavor of your brownies.
Step 3: Incorporate the Eggs and Flavor
Next, crack in four large eggs, one at a time, mixing well after each addition. Add a splash of pure vanilla extract and a pinch of salt, ensuring all ingredients are fully incorporated. Continue to mix for about 1-2 minutes, until the batter appears thick and creamy, creating a delicious base for your Chewy REESE’S PIECES Peanut Butter Brownies.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking powder, ensuring there are no lumps. Once combined, gently fold the flour mixture into the wet batter using a spatula. Stop mixing as soon as no dry flour remains, preventing the brownies from becoming cakey and maintaining their desired chewy texture.
Step 5: Prepare the Brownie Batter
Pour the brownie batter into your prepared baking pan, using a spatula to spread it evenly across the bottom. This will help the brownies bake uniformly. The thick batter should almost fill the pan, creating a rich, fudgy foundation for your treat.
Step 6: Add REESE’S PIECES
Before baking, generously sprinkle REESE’S PIECES over the top of the brownie batter, ensuring even distribution. Their colorful crunch will add both a delightful texture and flavor. Press them gently into the batter to ensure they bake into the brownies, turning them into irresistible chewy treats.
Step 7: Bake to Perfection
Place the pan in the preheated oven, and bake for 30-35 minutes. Keep an eye on your brownies; they are done when the top feels firm and the edges start to pull away from the sides of the pan, but the center remains slightly moist. This is key to achieving that chewy consistency.
Step 8: Cooling the Brownies
After baking, remove the brownies from the oven and let them cool in the pan for at least 30 minutes. This cooling period allows the flavors to meld and helps with slicing. Once cooled, carefully lift them out using the parchment overhang, and let them rest on a cutting board before cutting into squares.
Step 9: Slice and Serve
With a sharp knife, cut the Chewy REESE’S PIECES Peanut Butter Brownies into even squares, enjoying the delightful contrast of chewy brownie and crunchy candy. Serve them warm or at room temperature, and share this sweet treat with friends and family, making every moment a delightful experience!
