Bumpy cake recipe

Here is a delicious Bumpy Cake recipe that features a rich chocolate cake with a distinctive bumpy frosting. Start by baking a 9x13-inch chocolate cake using your favorite recipe or a box mix. Once the cake has cooled, prepare the frosting. In a saucepan, melt 1/2 cup of butter over medium heat, then whisk in 1/2 cup of cocoa powder. Gradually add 2 cups of powdered sugar and 1/4 cup of milk, beating until smooth. Stir in 1 teaspoon of vanilla extract. Spread a thin layer of this frosting over the cake. For the bumpy effect, pipe or spoon additional frosting in small mounds across the cake. Let the frosting set before slicing. Enjoy the rich, chocolatey layers with a delightfully textured topping.
