Reeses Brownies combine two iconic flavors that were destined to be together: rich chocolate and creamy peanut butter. These indulgent treats feature a fudgy brownie base studded with Reese’s peanut butter cups and topped with a smooth peanut butter layer that will satisfy even the most intense chocolate cravings. If you’re a fan of Reese’s Pieces Cookies or other peanut butter desserts, these brownies will quickly become your new obsession. Let me walk you through creating this irresistible dessert that perfectly balances sweet and salty flavors.
Nutritional Benefits
While Reeses Brownies are definitely an indulgence, they do offer some nutritional benefits. The peanut butter provides protein and healthy fats, while dark chocolate (if used) contains antioxidants. Enjoying these treats in moderation can be part of a balanced lifestyle.

Equipment Needed
– 9×13 inch baking pan
– Parchment paper
– Mixing bowls (large and medium)
– Electric mixer or stand mixer
– Rubber spatula
– Measuring cups and spoons
– Microwave-safe bowl
– Cooling rack
– Sharp knife
Step-by-Step Instructions

1. Prepare your pan: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy removal later.
2. Make the brownie base: In a large bowl, melt butter in the microwave. Add sugar and whisk until combined. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract.
3. Add dry ingredients: In a separate bowl, whisk together flour, cocoa powder, and salt. Gradually add this mixture to the wet ingredients, stirring just until combined. Don’t overmix.
4. Add the peanut butter cups: Fold in 8 chopped Reese’s peanut butter cups and 1/4 cup chocolate chips into the batter.
5. Pour and bake: Transfer the batter to your prepared pan, spreading it evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
6. Prepare the peanut butter layer: While the brownies are baking, melt 1 cup of peanut butter in a microwave-safe bowl until smooth and pourable.
7. Add the toppings: When the brownies are done, immediately pour the melted peanut butter over the hot brownies, spreading it evenly. Sprinkle with remaining chopped Reese’s cups and chocolate chips.
8. Cool completely: Allow the Reeses Brownies to cool completely in the pan before cutting. For clean cuts, refrigerate for at least 2 hours before slicing.

Troubleshooting & Pro Tips
– Brownie texture too cakey? Use less flour or bake for a shorter time.
– Peanut butter not spreading easily? Make sure it’s thoroughly melted and pour it over the brownies while they’re still hot.
– Want more peanut butter flavor? Add 1/4 cup peanut butter to the brownie batter itself.
– For cleaner cuts: Use a sharp knife dipped in hot water and wiped clean between cuts.
– Extra indulgence: Drizzle melted chocolate over the top after the peanut butter layer.
– Enhance the flavor: Sprinkle flaky sea salt on top to contrast with the sweetness.
Storage & Make-Ahead Tips
– Counter storage: Store in an airtight container at room temperature for up to 3 days.
– Refrigerator: Keep fresh for up to 1 week in the refrigerator.
– Freezer: These brownies freeze beautifully! Cut into individual squares, wrap in plastic wrap, and freeze in an airtight container for up to 3 months.
– Make ahead: You can prepare the brownie batter up to 24 hours in advance and store it covered in the refrigerator until ready to bake.
– Serving tip: For a warm dessert, microwave individual brownies for 15-20 seconds before serving.

FAQ
Can I use a boxed brownie mix instead of making the batter from scratch?
Yes! Simply prepare the boxed mix according to package directions and fold in the chopped Reese’s cups before baking.
How do I know when the brownies are done baking?
Insert a toothpick into the center—it should come out with a few moist crumbs, not completely clean (which would indicate overbaking).
Can I make these brownies gluten-free?
Absolutely! Substitute the all-purpose flour with a 1:1 gluten-free flour blend.
What if I don’t have Reese’s peanut butter cups?
You can use chocolate chips and swirl in peanut butter, or try another candy with a similar flavor profile.
Can I reduce the sugar in this recipe?
Yes, you can reduce the sugar by up to 1/4 cup without significantly affecting the texture.
Why did my brownies turn out too dry?
They might have been baked too long. Every oven is different, so start checking for doneness a few minutes early.
How can I make these brownies vegan?
Use plant-based butter, flax eggs, and dairy-free chocolate. Ensure your peanut butter cups are vegan as well, or make homemade vegan versions.
