In the bottom of a 9×13 baking dish, lay ice cream sandwiches flat and flush against one another covering the entire bottom to create layer 1 of two.You may have to cut an ice cream sandwich in half for them to cover the bottom of the dish evenly. Place in the fridge until step 6.
In a large mixing bowl, combine whipping toppings, cream cheese powdered sugar, and cake mix using an electric hand mixer. Mix until smooth.
Fold in vanilla and 1-½ cups of Oreo crumbs. Mix well again.
Divide the mixture into two bowls. Working one at a time, add a different color food coloring to the bowls starting with 3-4 inches at a time to create one red mixture and one blue mixture. Blend using a hand mixer until the color is fully worked in. Add more food coloring if needed to reach the desired color.
Spread the red layer over the first ice cream sandwich layer evenly using a rubber spatula.
Top the layer with the second layer of ice cream sandwiches, repeating step 1.
Top with the blue mixture spreading evenly over top.
Top with remaining crushed Oreos and then the sprinkle mix covering the majority of the surface (make your cake full but leave enough space to see the blue layer).
Cover and place inside the freezer for 6 hours or overnight.
Cut carefully with a knife or metal spatula to serve. Top with additional whipped topping, Oreo crumbs, cherries, and sprinkles if desired.
