Preheat your oven the 350 degrees, grease a muffin tin or small cake pan (Coconut oil works great for this!) and set aside.
In a microwave-safe bowl or stove-top, melt your nut butter.
Blend the banana, nut butter and cocoa powder in the blender until mixture is smooth.
Pour the mixture into the greased pan and bake for around 20 minutes or until baked thoroughly.
Remove from the oven and allow to cool completely before slicing.(refrigeration gives the best texture)
