MINI FUNFETTI CAKE This recipe makes a small batch (just 2 small cakes) that will satisfy your cake craving. These little cakes are perfect for any small party at home or even just a Tuesday night when you need a little something sweet. In order to bake these cakes, I used 2 BPA free aluminum cans. If you don’t feel comfortable baking in cans, you can make one 4-inch round cake. and candles to decorate these colorful cakes for any occasion.
