BANANA CAKE

This is the ultimate snack or breakfast cake. This recipe comes from my Banana Bread recipe. Making some small changes to that recipe such as creaming the butter and sugars, and adding baking powder for a little extra lift, turns my favorite bread into this tender banana cake.

This cake is made even more tender from using buttermilk. The same as the banana bread recipe. If you’re like me and don’t typically have buttermilk on hand its it’s an easy fix.

To make sour milk to use in place of buttermilk: Add about 2 teaspoons of lemon juice or plain white vinegar to your measuring cup, then pour the milk in to reach 1 cup. Let it sit briefly. This will make sour milk. Perfect for baking, and gets the same results as using buttermilk.

The recipe has instructions for baking the banana cake in an 8×8, 9×9 or 9×13 pan.

CRUMB TOPPING

Giving this banana cake a crumb topping puts it into the breakfast category. Almost like a coffee cake.

The crumb topping is easy to make. Combine light brown sugar, cinnamon and flour. Then drizzle some melted butter in. Stir together with a fork to combine and create the large crumbs.

If the crumbs are too small and it’s not sticking together into big crumbs, add just a bit more melted butter.

On the other hand if the crumb seems really wet and wanting to make one large “crumb” add just a bit more flour to dry it up a bit to create the crumbs.
