1) Put the butter in a small sauce pan and place it on the stove top around medium heat. 2) While the butter is melting, take the two bananas and place them in a blender on puree setting, the smoother the texture, the better. 3) Take the banana puree and mix in all the other ingredients into the sauce pan. Stir until it is a very smooth consistency (roughly 3-5 minutes). 4) Remove from heat and serve.
