Ingredients
For these brownies, the foundation is a classic chocolate batter enriched with butter and peanut butter for extra moisture. The dry mix supplies structure, while the Reese’s Pieces bring a burst of salty‑sweet crunch. A touch of vanilla and a pinch of salt amplify the overall flavor, ensuring each bite feels balanced and indulgent.
Dry Ingredients
- 1 cup all‑purpose flour
- ½ cup unsweetened cocoa powder
- ½ teaspoon baking powder
- ¼ teaspoon fine sea salt
Wet Ingredients
- ½ cup unsalted butter, melted
- ½ cup creamy peanut butter
- 1 cup granulated sugar
- ½ cup brown sugar, packed
- 2 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- ½ cup whole milk
Mix‑Ins & Topping
- ¾ cup REESE’S Pieces candy‑coated peanuts
- ¼ cup mini chocolate chips (optional)
The melted butter and peanut butter create a glossy, tender crumb, while the combination of granulated and brown sugar adds both sweetness and a slight caramel note. Cocoa powder gives the brownies a deep chocolate flavor, and the milk loosens the batter just enough for a soft, chewy texture. Finally, the Reese’s Pieces provide a delightful crunch and a burst of salty‑sweet flavor that makes each bite unforgettable.
Step-by-Step Instructions
Preparing the Batter
Start by preheating your oven to 350°F (175°C) and greasing a 9×13‑inch baking pan. In a medium bowl whisk together the flour, cocoa powder, baking powder, and salt; this ensures even distribution of leavening and prevents clumps of cocoa.
Mixing Wet Components
- Combine butter and peanut butter. In a large mixing bowl, pour the melted butter and stir in the creamy peanut butter until the mixture is smooth and glossy. The emulsion creates a moist base that keeps the brownies chewy.
- Incorporate sugars. Add the granulated and brown sugars to the butter‑peanut mixture. Beat with a handheld mixer on medium speed for 2‑3 minutes until the mixture lightens slightly and the sugars begin to dissolve.
- Blend eggs and vanilla. Crack the eggs into the bowl, add the vanilla extract, and continue mixing until the batter is uniform. The eggs provide structure, while the vanilla lifts the overall flavor.
- Stir in milk. Pour the milk gradually, mixing just until incorporated. Too much mixing can develop gluten, making the brownies tough, so stop as soon as the batter looks smooth.
Bringing It All Together
- Fold in dry ingredients. Using a spatula, gently fold the flour mixture into the wet batter in two additions. Stop mixing when no streaks remain; this keeps the crumb tender.
- Add the candy. Sprinkle the REESE’S Pieces (and chocolate chips, if using) over the batter and fold lightly. The candy should be evenly distributed but not over‑mixed, preserving its crunchy texture.
- Spread the batter. Transfer the batter to the prepared pan, smoothing the top with a spatula. The surface should be slightly uneven—this helps the brownies rise uniformly.
- Bake. Place the pan in the preheated oven and bake for 22‑25 minutes. The edges will look set while the center remains slightly soft; a toothpick inserted near the edge should come out with a few moist crumbs but no wet batter.
- Cool and cut. Allow the brownies to cool in the pan on a wire rack for at least 15 minutes before cutting into squares. Cooling lets the crumb set, making clean cuts and preserving the chewy texture.
Tips & Tricks
Perfecting the Recipe
Room‑temperature eggs. Using eggs that are not cold helps them blend more easily with the butter, creating a smoother batter and preventing lumps.
Don’t over‑mix. Once the flour is added, stop mixing as soon as it disappears. Over‑mixing develops gluten, which can make brownies cakey instead of chewy.
Even candy distribution. Toss the Reese’s Pieces with a teaspoon of flour before folding them in; this prevents them from sinking to the bottom.
Check at the right time. Begin checking the brownies at 20 minutes; ovens vary, and a slight underbake yields the best chewy texture.
Flavor Enhancements
For an extra depth of flavor, swirl a tablespoon of caramel sauce into the batter before baking, or sprinkle a pinch of flaky sea salt on top after they come out of the oven. Both add a sophisticated salty‑sweet contrast that elevates the brownies.
Common Mistakes to Avoid
Avoid opening the oven door during the first 15 minutes; the sudden temperature drop can cause the brownies to collapse. Also, resist the urge to over‑bake—dry brownies lose their signature chewiness.
Pro Tips
Use quality cocoa. A good, unsweetened cocoa powder provides a richer chocolate flavor and a deeper color.
Line the pan. Parchment paper makes removal effortless and keeps the brownies from sticking, preserving their neat edges.
Cool completely before storing. Allow the brownies to reach room temperature; this prevents condensation that could make the top soggy.
Freeze for later. Portion the brownies, wrap tightly, and freeze. They reheat beautifully and retain their chewiness.
Variations
Ingredient Swaps
Swap the classic REESE’S Pieces for chocolate‑covered pretzel bits for a salty crunch, or use almond butter instead of peanut butter for a nuttier profile. You can also replace cocoa powder with melted dark chocolate for an ultra‑rich brownie.
Dietary Adjustments
For gluten‑free brownies, use a 1‑to‑1 gluten‑free flour blend. Vegans can replace butter with coconut oil and the eggs with a flax‑egg mixture (1 tablespoon ground flaxseed + 3 tablespoons water per egg). Use a sugar substitute like erythritol if you need a low‑sugar version.
Serving Suggestions
Serve warm with a scoop of vanilla or peanut butter ice cream, drizzle with chocolate ganache, or simply dust with powdered sugar. For a brunch twist, top each square with a dollop of whipped cream and fresh berries.
Storage Info
Leftover Storage
Allow the brownies to cool completely, then cut them into squares and store in an airtight container. In the refrigerator they stay fresh for 4‑5 days. For longer keeping, wrap individual portions in plastic wrap, place them in a freezer‑safe bag, and freeze for up to 3 months.
Reheating Instructions
Reheat refrigerated brownies in a 300°F (150°C) oven for 8‑10 minutes, or microwave a single square for 20‑30 seconds. If reheating from frozen, add an extra minute in the oven. A quick drizzle of milk or extra peanut butter before serving revives the moist texture.
