This recipe is made with simple ingredients that also have easy substitutions if you don’t have everything on hand. Here’s what you’ll need:

  • Bananas: make sure your bananas are very ripe for ultimate sweetness.
  • Oat flour: Use gluten-free oat flour if needed or replace with regular all-purpose flour if preferred.
  • Vegan butter: use vegan butter for dairy-free or replace with regular butter.
  • Coconut sugar: use this as a natural, unrefined sweetener or replace with brown sugar.
  • Eggs: I recommend organic pasture-raised eggs.
  • Vanilla Extract: use a high-quality vanilla extract.
  • Cinnamon: for extra flavor.
  • Baking soda, baking powder, and salt.

Extra Helpful Baking Tips

  • I use oat flour because it’s rich in nutrients & antioxidants and responds well in baking recipes. Use gluten-free oat flour if needed or replace with regular all-purpose flour.
  • Make sure bananas are very ripe – but not rotten.
  • Be sure to use an 8×8 inch pan or 9×9 inch square pan.
  • Line pan with parchment paper before baking to help successfully remove the finish product when finished.

When enjoying this crumbly cake, I highly suggest reheating it and serving warm. It becomes even more buttery, moist, and decadent – it’ll be hard to just eat one slice at a time.

The whole family will love this wholesome dessert!
