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.
