If you love peanut butter cups — you’ll adore these Halloween Fudgy Peanut Butter Chocolate Swirl Brownies. A decadent treat for sure, perfect for Halloween, or even rooting for your favorite “black and orange” team at a tailgate. These brownies are dense, fudgy, peanut buttery… and oh my — so good!



1/2 cup butter, melted
1 tablespoon vegetable oil
1 cup sugar
2 eggs
11/2 teaspoon vanilla
3/4 cup flour
1/2 cup unsweetened cocoa powder
1/2 teaspoon baking powder
1/4 teaspoon salt

Peanut Butter Swirl

3 tablespoons butter, melted
1/2 cup peanut butter
1/4 cup powdered sugar
red food coloring
yellow food coloring


Preheat oven to 350 degrees F and line a 9 x 9-inch baking pan with overhanging layers of parchment paper. Set aside.

In a microwave-safe bowl, combine 1/2 cup butter and chocolate chips. Microwave in 30-second increments, whisking after each, until completely smooth. Then mix in the granulated sugar until completely combined; whisk in the eggs and vanilla.

With a spatula or spoon fold in the flour, cocoa powder, baking powder, and salt. Set aside.

For the Peanut Butter Swirl: Melt butter in a medium-size bowl and add a few drops of yellow and red food coloring, until the butter has a nice orange color. Add the peanut butter and confectioners sugar and mix together until smooth.

Drop big spoonfuls of the chocolate brownie batter randomly into the prepared pan. Top with spoonfuls of the peanut butter batter. Using a knife, swirl the batters together. Sprinkle with additional chocolate chips.

Bake 30 to 35 minutes or until a toothpick inserted in center comes out mostly clean. Cool completely; about 1 hour. For 16 brownies, cut into 4 rows by 4 rows.
