Preheat the oven to 350 degrees Fahrenheit and add 12 paper liners to a muffin tin pan.
In a medium bowl, whisk together the eggs, mashed banana, oil, maple syrup, and vanilla extract.
In a separate large bowl, mix together the almond flour, coconut flour, cocoa powder, baking powder, baking soda, and salt.
Add the wet ingredients to the dry ingredients and stir until combined.
Spoon the batter into the muffin liners.
Bake for 20-22 minutes until you are able to insert a toothpick into the center and have it come out clean.
