Peanut Butter Cup Brownies Recipe
Introduction
Indulge in the perfect combination of rich chocolate and creamy peanut butter with these Peanut Butter Cup Brownies. This delightful treat pairs fudgy brownies with whole peanut butter cups for an irresistible dessert that’s sure to satisfy any sweet tooth.

Ingredients
- 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
- 24 full-size chocolate peanut butter cups
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Line a 9×13 inch rectangular baking pan with parchment paper and spray it lightly with nonstick cooking spray.
- Step 2: Using a hand mixer or stand mixer, beat together the melted butter and sugar until well combined.
- Step 3: Add the vanilla extract and eggs, one at a time, beating thoroughly after each addition to ensure a smooth mixture.
- Step 4: Sift together the flour, cocoa powder, salt, and baking powder in a separate bowl, then gradually add this dry mixture to the wet ingredients, beating until just combined.
- Step 5: Spread half of the brownie batter evenly across the bottom of the prepared pan. Since it will be thick, take your time to cover the entire surface carefully.
- Step 6: Arrange the chocolate peanut butter cups in neat rows over the batter layer, pressing them gently to set in place.
- Step 7: Spread the remaining brownie batter over the peanut butter cups, smoothing it evenly with a spatula.
- Step 8: Bake in the preheated oven for about 30 minutes. The brownies are done when they are set in the center and a toothpick inserted comes out with a few moist crumbs.
- Step 9: Remove the pan from the oven and let the brownies cool completely before lifting them out using the parchment paper edges.
- Step 10: Cut into squares and serve. Enjoy your rich and gooey peanut butter cup brownies!
Tips & Variations
- For extra fudginess, slightly underbake the brownies by removing them a few minutes earlier.
- Try swapping salted butter for unsalted and adjust salt accordingly to control the saltiness.
- Add chopped nuts or chocolate chips to the batter for additional texture and flavor.
- If you prefer smaller bites, use mini peanut butter cups instead of full-size ones.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. To reheat, warm individual pieces in the microwave for 10-15 seconds to soften the chocolate and enhance the gooey texture.
How to Serve
Serve this delicious recipe with your favorite sides.
FAQs
Can I use natural peanut butter cups instead of chocolate peanut butter cups?
Natural peanut butter cups may vary in consistency and sweetness, but you can certainly use them. Just be mindful that texture and flavor might differ slightly from the traditional combination.
Do I need to line the baking pan with parchment paper?
While not absolutely necessary, lining the pan with parchment paper makes it much easier to lift the brownies out and prevents sticking, resulting in cleaner cuts and easier serving.

Instructions
