Reese’s Stuffed Brownies Recipe
Introduction
Rich, chewy brownies get an irresistible upgrade with hidden Reese’s peanut butter cups inside and a creamy peanut butter frosting on top. This easy-to-make dessert perfectly balances chocolate and peanut butter flavors for a crowd-pleasing treat.

Ingredients
- 1 box brownie mix + ingredients needed on the package
- 15 full-sized Reese’s Cups
- 3/4 cup creamy peanut butter
- 1/2 cup unsalted butter (softened)
- 2 1/4 cups powdered sugar
- 4 tablespoons heavy cream
- 1 1/2 teaspoons vanilla extract
Instructions
- Step 1: Preheat the oven to 350°F. Line a 9×13 baking dish with parchment paper and set aside.
- Step 2: In a large bowl, prepare the brownie mix according to the package instructions. Spread about two-thirds of the batter evenly into the prepared baking dish.
- Step 3: Arrange the 15 full-sized Reese’s Cups on top of the batter, pressing them in slightly so they stay in place.
- Step 4: Gently spread the remaining batter over the Reese’s Cups until fully covered.
- Step 5: Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out mostly clean. A few moist crumbs are fine, but avoid wet batter.
- Step 6: Remove from the oven and place the brownies on a wire rack to cool completely.
- Step 7: To make the frosting, combine the peanut butter and softened butter in a large bowl. Beat with an electric mixer until smooth and creamy.
- Step 8: Gradually add the powdered sugar, mixing well after each addition. Scrape down the sides of the bowl as needed. The mixture should be thick.
- Step 9: Add the heavy cream and vanilla extract, then whip the frosting on medium-high speed for about 2 minutes until light and fluffy.
- Step 10: Use the parchment paper to lift the cooled brownies out of the baking dish and onto a serving tray.
- Step 11: Spread the peanut butter frosting evenly over the top of the brownies. Serve immediately or add extra toppings if desired.
Tips & Variations
- For an extra crunchy texture, sprinkle chopped peanuts or Reese’s pieces on top of the frosting.
- Try using dark chocolate or peanut butter cup alternatives to customize the flavor.
- If you prefer a thicker frosting, chill it briefly before spreading.
Storage
Store leftover brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. Before serving, you can bring refrigerated brownies to room temperature or warm briefly in the microwave for a softer texture.

Ingredients
Brownie Batter
- 1 box brownie mix (with ingredients required as per package instructions)
- 15 full-sized Reese’s Cups
Peanut Butter Frosting
- 3/4 cup creamy peanut butter
- 1/2 cup unsalted butter, softened
- 2 & 1/4 cups powdered sugar
- 4 tablespoons heavy cream
- 1 & 1/2 teaspoons vanilla extract
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking dish with parchment paper, ensuring easy removal of the brownies after baking, then set aside.
- Mix Brownie Batter: In a large bowl, prepare the brownie mix according to the package instructions. Once mixed, spread about two-thirds of the batter evenly into the prepared baking dish to create the base layer.
- Add Reese’s Cups: Arrange 15 full-sized Reese’s Cups evenly over the brownie batter in the pan, gently pressing them down slightly so they nestle into the batter.
- Top with Remaining Batter: Carefully spread the remaining one-third of the brownie batter over the Reese’s Cups, fully covering them to encase the peanut butter cups within the brownies.
- Bake Brownies: Place the baking dish into the preheated oven and bake for 25 to 30 minutes. Test doneness with a toothpick inserted into the center; it should come out with a few moist crumbs but no wet batter.
- Cool the Brownies: Remove the brownies from the oven and transfer the pan to a wire rack. Allow brownies to cool completely to room temperature before frosting.
- Prepare Peanut Butter Frosting: In a large bowl, beat together the softened butter and creamy peanut butter using an electric mixer until smooth and creamy.
- Add Powdered Sugar: Gradually add the powdered sugar a bit at a time, mixing well after each addition and scraping down the bowl sides to combine thoroughly. The frosting will become thick.
- Incorporate Cream and Vanilla: Add the heavy cream and vanilla extract, stirring until combined. Increase mixer speed to medium-high and whip for 2 minutes until the frosting becomes light, fluffy, and spreadable.
- Remove Brownies from Pan: Use the edges of the parchment paper to carefully lift the cooled brownies out of the baking dish onto a flat surface.
- Frost the Brownies: Spread the peanut butter frosting evenly across the top of the brownies. Serve immediately or add your favorite toppings for extra flair.
Notes
- Ensure brownies are completely cooled before frosting to prevent melting.
- You can substitute the brownie mix with your favorite homemade brownie recipe if preferred.
- Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- For firmer frosting, refrigerate for 15 minutes before spreading.
- Optional toppings like chopped peanuts or chocolate chips can add extra texture and flavor.
