Ingredients
For the Brownies
- 1 cup unsalted butter, melted
- 1 ½ cups granulated sugar
- 1 cup brown sugar
- 4 large eggs
- 1 tablespoon vanilla extract
- 1 cup unsweetened cocoa powder
- 1 cup all purpose flour
- ½ teaspoon salt
- ½ teaspoon baking powder
For the Peanut Butter Layer
- 16 mini peanut butter cups (unwrapped)
Optional Topping
- ½ cup chocolate chips
- Extra chopped peanut butter cups
Step-by-Step Instructions
1. Prepare the Baking Pan
Begin by preheating the oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper or lightly grease it with butter. This step helps the brownies release easily after baking and makes cleanup much easier.
2. Mix the Butter and Sugars
Pour the melted butter into a large mixing bowl and add the granulated sugar and brown sugar. Whisk everything together until smooth and glossy. This mixture forms the base of the brownies and helps create their rich texture.
3. Add the Eggs and Vanilla
Crack the eggs into the bowl one at a time while mixing. Stir well after each addition so the batter becomes thick and smooth. Add the vanilla extract next and continue mixing until everything blends together evenly.
4. Combine the Dry Ingredients
In another bowl, whisk together cocoa powder, flour, salt, and baking powder. Slowly add this dry mixture into the wet batter while stirring gently. Continue mixing just until the ingredients combine and the batter becomes thick and chocolatey.
5. Layer the Batter and Peanut Butter Cups
Spread about half of the brownie batter into the prepared baking pan. Place the mini peanut butter cups evenly across the surface, leaving small gaps between them. Spoon the remaining batter on top and carefully spread it so the candies are fully covered.
6. Add Optional Toppings
Sprinkle chocolate chips or chopped peanut butter cups over the surface if you enjoy extra chocolate flavor. These toppings melt slightly during baking and add more texture to the finished brownies.
7. Bake the Brownies
Slide the pan into the oven and bake for about 30 to 35 minutes. The edges should look set while the center remains slightly soft. Insert a toothpick near the edge to check for doneness since the peanut butter cups in the middle will stay creamy.
8. Cool and Slice
Allow the brownies to cool completely in the pan before cutting. As they rest, the chocolate firms up and the peanut butter layer settles. Once cooled, slice the brownies into squares and serve.
Serving Suggestions
Freshly cut Peanut Butter Cup Brownies taste wonderful on their own, especially while the chocolate still feels soft and rich. A simple square served with a cup of coffee or tea makes a perfect afternoon treat.
Another delicious option involves warming a brownie slightly and adding a scoop of vanilla ice cream on top. The ice cream slowly melts into the chocolate, creating a creamy dessert combination.
Some people enjoy drizzling warm chocolate sauce or melted peanut butter over the brownies before serving. This extra topping adds shine and even more flavor.
For gatherings or dessert tables, smaller brownie squares arranged on a platter look beautiful and inviting. Guests can grab a piece easily and enjoy the chocolate and peanut butter layers.
Cold milk also pairs perfectly with these brownies. The creamy drink balances the rich chocolate flavor and makes every bite even more satisfying.
Tips & Variations
High quality cocoa gives the brownies a deeper chocolate flavor.
Slightly soft centers keep the brownies moist and fudgy.
Peanut butter filled chocolate squares also work well in this recipe.
A small handful brings a crunchy texture to the brownies.
Drop spoonfuls of peanut butter into the batter and swirl lightly for extra flavor.
Cooling the brownies completely helps create clean, neat squares.
Frequently Asked Questions
Can I use regular sized peanut butter cups?
Yes. Cut them into halves or quarters so they fit evenly inside the brownie batter.
How should I store these brownies?
Keep them in an airtight container at room temperature for about three days. Refrigeration can extend freshness up to five days.
Can I freeze peanut butter cup brownies?
Yes. Wrap individual squares tightly and store them in the freezer for up to two months.
Why are my brownies dry?
Overbaking usually causes dry brownies. Removing them while the center still looks slightly soft helps keep them moist.
Can I make them gluten free?
A 1 to 1 gluten free flour blend usually works well in place of regular flour.
Do the peanut butter cups melt completely?
They soften during baking but stay creamy inside the brownies, creating a rich peanut butter center.
