Sticky Butterscotch Banana CakeThis cake tastes so good, you'll be surprised at how easy it is to make. The main cake part is made of aquafaba, the liquid you find in a can of canned chickpeas. If you don't have any, use about 5 egg whites. Sometimes I use a mixture of both. Since the cake is so light and fluffy, the butterscotch chips mix with the banana and sink to the bottom, making a luxurious sticky butterscotch sauce to use as topping. Don't worry, it ribbons itself in the middle of the cake, too. What a delight!
