You get chocolate, vanilla, and strawberry all in one dessert… which is like the three musketeers of best flavors! It’s such a fun twist on a classic ice cream cake made with ice cream sandwiches.

Also, just a heads up… a little goes a looong way.

This is a rich, layered dessert with two full layers of ice cream sandwiches, so it definitely feels indulgent.
