You'll need a box of cake mix, either spice, yellow, or chocolate. Follow the directions on the back of the box for the cake, however do NOT add the oil, and instead add 1 teaspoon baking soda. Now if you are using anything else but the spice, you can add your own spices in for flavor. I use cinnamon, nutmeg, and cloves. Now add 4 very ripe bananas. Mix this altogether very thoroughly, then follow the boxed cake's directions on cooking it. This makes an amazingly moist and delicious cake.
You can use any frosting, but I like this one.
2 Cups sifted confectioners' sugar
1/2 cup butter, softened
1 tspn vanilla extract
2 tbspn milk
2 tbspn cocoa powder, optional for chocolate frosting.
Cream sugar butter and vanilla. Add a small amount of milk, 1 to 2 tblps. Add cocoa if desired and beat until fluffy. If frosting is too sweet, add a little more milk.
