Instructions

Preheat the oven to 350℉ and line a cookie sheet with parchment paper.

In a large bowl, combine cake mix, oil, eggs, and flour. Mix together using a wooden spoon until a dough is created.

Scoop dough using a cookie scoop, and arrange the rounded scoops on the cookie sheet, ensuring a 2 inch gap between each.

Create a hollow well in the center of each scoop of dough by using the curved back of a measuring teaspoon.

Place the pan in the oven and let it bake for 10 minutes.

Combine the peanut butter and powdered sugar, shaping the mixture into 24 small balls, approximately 1 teaspoon in size.

After the cookies finish baking, take them out of the oven and place a peanut butter ball in the well you created. Carefully press down on the ball to flatten it.

Place the chocolate chips in a small bowl and microwave them on high for 30 seconds. Take them out and mix thoroughly, then microwave for an extra 15 seconds. Stir well until all the chocolate is completely melted.

Place a small spoonful of chocolate on top of each flattened peanut butter ball.

Allow the chocolate to set by refrigerating it for 30 minutes.

Tips & Tricks (5)

Chill Peanut Butter Filling 🧊
Refrigerate your peanut butter mixture for at least 30 minutes before filling to prevent it from melting into the warm brownie base and maintain distinct layers.
Don't Overmix the Brownie Base 🥄
Stir the brownie mix batter just until combined to keep cookies chewy and fudgy rather than cake-like, as overmixing develops gluten that toughens the texture.
Use Parchment Paper for Easy Release 📄
Line your baking sheets with parchment paper to prevent sticking and ensure clean, intact cookies with perfectly formed buckeye-style appearance.
Partially Bake Before Filling ⏱️
Bake the brownie base for 8-10 minutes until set but still warm, then add peanut butter filling and chocolate topping to prevent soggy bottoms while ensuring cohesion.
Temper Chocolate for Glossy Finish 🍫
Melt chocolate chips with a small amount of coconut oil for a smooth, professional-looking coating that sets quickly and has an elegant snap rather than a dull finish.
