Notes

Cooking Tips:
  • Use a very ripe banana for a sweeter cake and stronger flavor.
  • If the cake is too dry, add a teaspoon of almond milk to the batter.
  • Over-microwaving can make the cake rubbery, so start with 90 seconds and adjust as needed.
  • Sprinkle a pinch of sea salt on top to enhance sweetness
