Preheat your oven to 350 degrees. Spray two 8 inch round cake pans with cooking spray, then line the bottom of each pan with parchment paper.
In a stand mixer with the whisk attachment, beat cake mix, melted vanilla ice cream, and eggs on high until smooth.
13.35 vanilla cake mix, 2 cups vanilla ice cream, 3 eggs
Divide the batter evenly between the two pans. You should have approximately 4 cups of batter total, so each pan will have about 2 cups of batter.
Bake for 20-22 minutes or until the top is an even golden brown. Cool in the pan for 10 minutes before flipping out onto a cooling rack to cool completely.
While the cakes are cooling, slice the bananas into 1/4 inch slices. Set them aside for now.
2 bananas
Use about a teaspoon of frosting to attach the first cake, right side up, to a cake board or a serving dish. Then pipe or spread the frosting over the top of the cake, approximately 1/4 of an inch thick.
3 cups vanilla frosting
Pipe a thick ring of the frosting around the edge of the cake. This will give you a barrier for the chocolate and banana filling and will keep everything from oozing out. Spread a thin layer of chocolate sauce inside the ring of frosting.
1/3 cup chocolate syrup
Arrange the banana slices over the chocolate sauce. You can do up to two layers of sliced bananas but try to keep the layers even. Don’t add more than two layers or you’ll run the risk of the top cake sliding off.
2 bananas
Top with the second cake, upside down over the chocolate banana filling. Press lightly to make sure that the cake adheres.
Frost the entire outside of the cake with the remainder of the frosting.
3 cups vanilla frosting
Drizzle the cake with chocolate and strawberry sauce. Top with swirls of Cool Whip and sprinkle with nuts, cherries and rainbow sprinkles!
1/3 cup chocolate syrup, 3-4 tablespoons strawberry syrup, 1 cup whipped topping or whipped cream, cherries, sprinkles, chopped peanuts
Once decorated, refrigerate for at least 10 minutes before slicing and serving.
