Preheat oven to 350'.Follow instructions with the cake mix as normal. After it is completely mixed add the two large mashed banans & mix through the batter. Put into cupcake holders and bake for 15 minutes....stick a toothpick in the center of one of the cupcakes...if it's still gooey continue baking for another 3 to 5 minutes. Once finished place on a cooling rack.
After cupcakes are completely cooled, frost the cupcakes and add the banana chips on top & enjoy!!
