First, my apologies: for being a day late posting this, and for referring to this as a “recipe.” I think it could be more appropriately be referred to as a how-to. It’s just so simple.
I knew the cake was already going to be over-the-top, so I wanted something a little lighter with a more subtle flavor for the cupcake topping. I decided to use Cool-whip as the base, then added about a quarter of a packet of instant banana pudding mix. You could use more or less depending on how strong you want the flavor. Paired with a chocolate cake mix from a box, it was the perfect foil to the banana split cake!
Enjoy!
