Frequently Asked Questions

Can I use a different type of ice cream sandwich? Yes. Chocolate, mint, strawberry, or even birthday cake-flavored sandwiches all work beautifully .

Can I make this ahead of time?Yes. This cake is perfect for making a day or two in advance. Just keep it in the freezer until ready to serve .
