Could these be any easier? It's almost a joke writing up this recipe.
Warm your griddle.
Throw your banana and two eggs into the blender, along with the nut butter and cinnamon (both are totally optional, though I like the flavor) and vanilla.
Blend until well mixed.
Pour these cakes, they will be thin but sturdy, and cook until golden.
*If you use cinnamon, these will be a bit darker in color.
Serve with real maple syrup.
Store remaining cakes in fridge.
