salted butter– For most of my baking I use salted butter, but unsalted butter works just fine here too.
granulated sugar– Granulated sugar is a fine sugar commonly used in baking/cookie recipes.
sour cream– Find sour cream in the dairy section of the grocery store. It keeps the cake soft and moist.
ripe bananas– When your bananas turn spotted brown, they’re perfect for baking.
