Anna discovered the recipe for this delicious morsel on Gina's Skinny recipes: skinnytaste.com. The cupcakes are delicious by themselves and then you inject them with banana pudding and make a vanilla pudding-type frosting and they are amazing. I think they are best the next day straight out of the refrigerator! Try them! You won't regret it.
P.S. My mom highly recommends this site for plenty of delicious, healthy recipes and now I do too!
