Then mash up 2 very ripe bananas in a separate bowl, which may remind you of making your little ones homemade baby food...which may then make you sad that you don't have babies young enough to make baby food for, which may in return have you thinking of having another baby....or maybe not...maybe that's just me. :) Add these mashed bananas to one bowl of cake batter and mix well.
Then 1 TBS at a time add in the banana batter on top of the chocolate then back to the chocolate and then banana, so forth and so on until the liners are 2/3rds full.
Then bake them as directed on the back of the cake box.
Now for the frosting...the best part in my opinion.
Cream together 1 (8oz) block of cream cheese, softened
2 TBS of butter,
and 1/2 cup of peanut butter until smooth.
Add in a splash of vanilla, 1/8 tsp of salt. Then slowly add in 2-3 cups of powdered sugar. Frost and try not to eat them all at once.
