1recipe Prepare the brownie layer using my Fudgiest Brownies recipe, but make it in a round 8-inch pan to match the round cake layers. We need one 8-inch round brownie layer. Bake the rest of the brownie batter in a small pan and save the remaining for the topping.
Place the chocolate chips and condensed milk in a bowl, heat in the microwave at 15-second intervals, and stir the mixture each time until the chocolate is smooth and lump-free. Add the vanilla extract and mix well.
Cover the mixture with cling wrap, ensuring the wrap touches the mixture. Chill the bowl in the fridge for two to three hours. The mixture will harden and have the consistency of play dough.
Use an ice cream scoop to scoop the mixture and make small ball sizes of small marble balls. Roll the balls in the cocoa powder and set aside.
½ cup Cocoa powder
