This unique banana oat angel food cake was submitted to us as a reader favorite. She adapted it from a recipe on Food.com and enjoyed it as her yearly birthday cake. We originally shared this recipe in 2006, but have since updated the post and edited the recipe just a touch.
Banana Angel Food Cake that’s Whipped Up with a Touch of Oats
This cake has added moisture from bananas and oats or oat flour for a unique texture. It’s more dense than traditional angel food cake, but has more lift than your average banana cake or bread thanks to the whipped egg whites. If you confuse eggs with dairy, you’re not alone. See this post: Are Eggs Dairy?
The easiest way to garnish this cake is to dust it with powdered sugar. Simply add powdered sugar to a fine mesh sieve, and tap the sieve as you hold it over the cake. A small sieve works best for this.
Alternatively, you can pour on a glaze. You can use my Rich Vanilla Icing or Buttery Maple Glaze (both in that cinnamon roll recipe).

- Bake for 1 hour, or until a toothpick inserted in the center of the cake comes out clean.
- Let cool for 5 minutes, then loosen the sides and carefully invert the cake onto a serving plate. Once cool, dust with powdered sugar, if desired.
