Preheat oven to 350 degrees.
1 package of yellow or white cake mix
2 - 3 over-ripe medium bananas
1 cup of sour cream, I use light
1/2 cup of milk, I use 1%
4 Tbs of cocoa powder
18 mini peanut butter cups
18 cupcake liners
In a large mixing bowl combine all ingredients EXCEPT cocoa powder and peanut butter cups Mix well until well blended
Divide batter in half and pour into another mixing bowl
In one mixing bowl add the cocoa powder and mix well
Line muffin tins with cupcake liners
Place peanut butter cup in the center of each liner
Add a large spoonful of the banana batter, then a large spoonful of the chocolate batter
Repeat until all cupcake liners are filled 3/4 to the top
Place in oven for 20 - 30 minutes. I have found that on the regular setting I needed 30 minutes, but in convection they were done in 20 minutes.
Let cool a good 20 minutes before offering to the kiddos!
fill the batter half and half...
