Using melted ice cream to make a cake is a simple and delicious idea. All you need is 2 cups of melted ice cream and 1 ½ cups of self-raising flour. Mix them together until smooth, pour into a loaf pan, and bake. You can use any ice cream flavor you like and upgrade the cake in various ways. For example, you can add sprinkles, chocolate chips, fresh strawberries, or whipped cream. You can even add homemade vanilla buttercream or chocolate frosting for a decadent touch.
