Preheat the oven: Start by preheating your oven to 350°F (175°C). Grease a baking pan to prevent sticking.
Mash bananas: In a large bowl, mash the ripe bananas until smooth.
Combine wet ingredients: Add the eggs, applesauce, and vanilla extract to the mashed bananas. Mix until all the ingredients are well combined.
Mix dry ingredients: In another bowl, combine the almond flour, baking powder, baking soda, and salt.
Combine wet and dry ingredients: Gradually add the dry ingredient mixture to the wet ingredients. Stir until just combined; don’t overmix.
Add optional ingredients: If you'd like, fold in nuts or chocolate chips for extra flavor.
Pour batter: Pour the batter into your greased baking pan, spreading it evenly.
Bake: Place in the oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Cool and serve: Let the cake cool for a bit before slicing and serving. Enjoy your delicious, sugar-free treat!
