Coconut Banana Breakfast Cake

My children think that having cake for breakfast is quite a treat, although this is not your typical cake; it is high in protein and low in sugar. In fact, it is completely free of any sweetener other than mashed ripe bananas! Since this cake is made with coconut flour, you will not be able to replace the eggs with an egg-substitute in this recipe. Serve with sliced fresh bananas and a dollop of sunflower butter or peanut butter.
