Expert Tips

  • Leave a generous overhang on all sides of your dish when you line it. You’ll use that later to cover it before freezing.
  • Fully soften your cream cheese to ensure the richest, creamiest marshmallow filling.
  • Fold your whipped topping into the cream cheese mixture, rather than mixing. This preserves that light, fluffy texture.
  • Eight hours is the minimum chilling time for this dessert, but overnight results in even better flavor!

S’mores Icebox Cake FAQs

Do you have questions about this recipe? Here are the answers to the most commonly asked questions.

How long will S’Mores icebox cake last?

You can store this icebox cake tightly covered for up to a month in the freezer.

Why was my S’mores icebox cake grainy?

If you didn’t fully soften your cream cheese, you may have small bits of raw cream cheese in the filling. In addition, freezing the icebox cake for longer than a month results in ice crystals that give the cake a grainy texture.

What are the best graham crackers to use for S’mores icebox cake?

For a traditional S’mores flavor, use cinnamon graham crackers. However, you can use any variety to change up the flavor to a tasty effect!
