Buckeye cookies have a chewy brownie cookie base topped with a layer of creamy peanut butter and finished with rich chocolate ganache. This easy recipe is perfect for Christmas or satisfying any peanut butter–chocolate craving.
In a microwave-safe bowl, heat butter and chocolate chips in the microwave for 30 seconds. Stir and heat in additional 15-second intervals, stirring after each, until melted and smooth. Set aside.
½ cup unsalted butter, 2 cups semisweet chocolate chips
In a medium mixing bowl, whisk together flour, cocoa powder, baking powder, and salt. Set aside.
1 ½ cups all-purpose flour, ¼ cup unsweetened cocoa powder, 1 ½ teaspoon baking powder, ¼ teaspoon salt
In a large mixing bowl, beat the brown sugar, eggs, and vanilla extract with a hand mixer or stand mixer until combined.
1 ¼ cup light brown sugar, 3 large eggs, 1 ½ teaspoon vanilla extract
Mix in the cooled chocolate.
Gradually mix in dry ingredients on low speed until just combined. Do not overmix. Cover and refrigerate dough for 1 hour (or longer)
Preheat the oven to 325°F. Line baking sheets with parchment paper. Scoop 1.5 Tbsp dough (or use a medium cookie scoop, I used #50), roll into balls, and place 2 inches apart. Bake for 13-16 minutes or until tops are set. Cool on baking sheet for 10 minutes, then transfer to a wire rack.
For the Peanut Butter Layer
Beat peanut butter and butter until smooth. Mix in vanilla and salt. Gradually mix in the confectioners' sugar until well combined.
1 ¼ cup creamy peanut butter, 6 Tablespoons unsalted butter, 1 teaspoon vanilla extract, pinch salt, 1 ½ cup confectioners sugar
Roll the peanut butter mixture into approx. 1 inch balls, flatten slightly into thick disks, and gently press onto tops of cookies.
For the Ganache
Place chocolate chips in a heatsafe bowl. Set aside. Heat cream in a small saucepan over medium-low until steaming, then pour over chocolate chips. Let sit for 5 minutes, then whisk until smooth.
1 ½ cup semi-sweet chocolate chips, ½ cup heavy whipping cream
Spoon ganache over each cookie. Let set for 30-60 minutes before serving or storing.
Notes
If dough is difficult to work with, chill it a bit longer.
You can also use the microwave to make the ganache. Add the chocolate chips and cream to a microwave safe bowl. Microwave for 40 seconds. Stir. Continue heating in 20 second increments and stirring until smooth.
Storage: Store cookies in an airtight container in the refrigerator for up to 5 days. These can be kept at room temperature for several hours for serving but longer than that I would recommend the fridge.
