Tips & Variations
- For extra fudgy brownies, avoid overbaking and check for doneness a few minutes early.
- Swap peanut butter cups for other filled chocolates if you prefer different flavors.
- Add chopped nuts to the batter for added texture and crunch.
- Use a dark cocoa powder for a richer chocolate flavor.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze airtight for up to 3 months. Reheat gently in the microwave to soften the chocolate before serving.

FAQs
Can I use natural peanut butter instead of peanut butter cups?
This recipe is designed for peanut butter cups which provide a creamy, chocolaty center. Using natural peanut butter will alter the texture and flavor but you can swirl it into the batter as an alternative.
How do I make sure the brownies don’t dry out?
Do not overbake; take them out as soon as a toothpick shows moist crumbs. Cooling completely in the pan helps retain moisture as well.

Ingredients
Brownie Batter
- ½ cup salted butter (melted and cooled)
- 1 ½ cups granulated sugar
- 2 teaspoons vanilla extract
- 3 large eggs
- ¾ cup all-purpose flour
- ½ cup unsweetened cocoa powder
- ½ teaspoon salt
- ½ teaspoon baking powder
Fillings
- 24 full-size chocolate peanut butter cups
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it’s ready for baking once the batter is prepared.
- Prepare Pan: Line a 9×13 inch baking pan with parchment paper and spray with nonstick cooking spray to prevent sticking and make removal easier.
- Mix Butter and Sugar: Using a hand mixer or stand mixer, beat the melted and cooled butter together with the granulated sugar until well combined and smooth.
- Add Vanilla and Eggs: Incorporate the vanilla extract, then add the eggs one at a time, beating thoroughly after each addition to create a smooth batter.
- Sift Dry Ingredients: Sift together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder to avoid lumps and help blend evenly into the batter.
- Combine Batter: Gradually add the sifted dry ingredients into the wet ingredients and beat until fully combined, forming a thick brownie batter.
- Layer Batter: Spread half of the thick brownie batter evenly across the bottom of the prepared baking pan with care to cover the surface.
- Add Peanut Butter Cups: Arrange the 24 full-size chocolate peanut butter cups neatly in rows over the first layer of batter, pressing slightly to nestle them in.
- Top with Remaining Batter: Gently spread the remaining batter over the peanut butter cups, smoothing evenly to encase them within the brownie layers.
- Bake: Place the pan in the preheated oven and bake for 30 minutes, or until the brownie batter is set in the center and a toothpick inserted in the middle comes out with just a few moist crumbs.
- Cool: Remove the brownies from the oven and let them cool completely in the pan to allow the batter to set fully around the peanut butter cups.
- Serve: Lift the cooled brownies out by the parchment paper edges, cut into pieces, and serve.
Notes
- Ensure the butter is cooled before mixing with eggs to prevent cooking the eggs prematurely.
- Using parchment paper for lining the pan helps in easy removal and clean-up.
- Do not overbake to maintain fudgy brownie texture; check doneness starting at 28 minutes if your oven runs hot.
- You can substitute salted butter with unsalted butter plus a pinch of salt if preferred.
- Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for longer shelf life.
