Bake the cupcakes according to the recipe instructions. For real banana split flavor, add 2 tablespoons of banana extract to your cake batter.
While the cupcakes are baking and cooling, place all three containers of canned icing in the freezer until firm -- about 20 minutes. Cold, firm icing is much easier to scoop.
Using a small cookie dough scoop, drop a small amount of the first flavor of icing on top of each cupcake while still cold and firm. Once each cupcake has a scoop of the first flavor, wash the scoop and repeat with the second and third flavors.
While the chocolate is still warm, place a candy cherry sour in the center of each cupcake and sprinkle with chopped peanuts.
