I love to make snack cakes! NO FORK needed! Just pick them up and take a bite! This one is moist and so flavorful! It needs no icing! It is a favorite of mine! It has a rich banana layer and velvety chocolate bottom.

BONUS: One piece is only 113 calories or 5 WW points!

I love it not only because it is low-calorie, but  because I really love the texture and the intense banana/chocolate combination. The low-calorie count is a bonus!  

See pictures how I made it in the slideshow below.

USE overripe bananas for a more intense banana flavor! 
FREEZE  overripe bananas that are past their prime in plastic freezer bags! Then microwave them to use in recipes!   Microwave 3 frozen bananas for 2 minutes to soften.
GO AHEAD!  Dust the tops with confectioner’s sugar if you want!!
