Rule of thumb: Any time you have the option to combine chocolate and peanut butter, go for it. These chewy REESE’S Peanut Butter Cup brownies are a surefire way to please a crowd and satisfy your sweet tooth.



½ cup neutral oil (like olive, coconut or vegetable)

2¾ cups chopped REESE’S Peanut Butter Cups, divided

⅓ cup sugar

⅓ cup brown sugar

2 eggs

1 teaspoon pure vanilla extract

1 cup all-purpose flour

½ teaspoon salt

Peanut Butter Swirl

3 tablespoons unsalted butter, melted

½ cup confectioners’ sugar

½ cup peanut butter


1. Preheat the oven to 350°F. Grease a 9-inch square baking pan, line it with parchment paper and then grease the parchment paper.

2. Make the Brownies: In a medium heat-safe bowl, combine the oil and 1¾ cups chopped Reeses Peanut Butter Cups. Heat the mixture over a pot of simmering water until the peanut butter cups are melted and relatively smooth. (You can also do this in a microwave-safe bowl in the microwave in 30-second intervals.)

3. Add the sugar and brown sugar, and mix to combine. Add the eggs one at a time and mix to combine. Stir in the vanilla extract.

4. Add the flour and salt, and mix to combine, but don’t overmix. Stir in the remaining 1 cup chopped peanut butter cups and mix until incorporated.

5. Pour the batter into the prepared pan and spread it into an even layer.

6. Make the Peanut Butter Swirl: In a small bowl, mix the melted butter with the confectioners’ sugar and peanut butter to combine. Drizzle the mixture over the brownie batter and use a paring knife or skewer to swirl the two together.

7. Bake until a toothpick inserted into the center comes out clean or with a few moist crumbs, 25 to 30 minutes. Cool completely before slicing and serving. Store leftovers in an airtight container at room temperature for up to a week.
