Preheat the oven to 350°F. Then butter or generously grease your angel food cake pan.
After the oats have soaked for 20 minutes add everything in each of the bowls together. Using a spatula gently stir batter together until combined.
Pour batter into your prepared pan and place in the oven to bake for 30 minutes.
When done remove the pan from the oven and allow cake to cool on the counter a bit before removing it from the pan.

Notes
Be sure to generously grease the baking pan. We like to use butter and feel it works best. You don't want to risk the cake sticking to the sides of the pan and prevent it from rising properly.
If you don't have an angel food cake pan you can also use a 9x9 cake pan or a bundt pan too.
