- 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.

If I want to add pumpkin puree to this recipe , should I add more oat flour?
Hi Kelly, It would definitely change the ratios, so I can’t promise results! You would need to add more flour and the baking time would most likely need to be adjusted! I would instead replace the banana with the pumpkin, then add pumpkin pie spices to the mix.
Where’s coffee in the recipe??
no coffee, its just called coffee cake because you pair it with coffee 🙂

Hi, I want the cake to have a coffee flavour. What can I do for that as your recipe has no coffee in it?
Although the recipe doesn’t call for any coffee and I’ve not tested it myself, you can try 1-2 teaspoons of instant coffee.
