When the weather heats up, these Peach Marshmallow Ice Cream Sandwich Bars are the kind of dessert everyone reaches for first. They’re cool, creamy, and layered with sweet peaches and fluffy marshmallow goodness between soft ice cream sandwiches.
Every bite brings together refreshing fruit, a light marshmallow layer, and a frozen, melt-in-your-mouth texture that makes this dessert perfect for summer gatherings or an easy make-ahead treat.

The best part
The first bite is wonderfully creamy with soft peaches tucked into a fluffy marshmallow filling. The ice cream sandwiches stay tender enough to bite through easily, while the peaches add bursts of juicy sweetness that make every layer feel light and refreshing.
A little note from my kitchen
This is one of those desserts that disappears surprisingly fast at family cookouts. I like making it the night before so it’s perfectly firm when it’s time to serve, and the peach flavor seems even brighter after everything has had time to chill together.
Would you add a drizzle of caramel on top, or keep it simple with fresh peaches?

Quick tips
Can I make this ahead?
Yes. These bars are perfect for making a day in advance. Keep them tightly covered in the freezer until ready to serve.
Can I swap the filling, flavor, fruit, or topping?
Absolutely. Try nectarines, strawberries, blueberries, mango, or even crushed vanilla cookies instead of graham crackers for a different twist.
Easy variation
For a peaches-and-cream version, stir a handful of crushed vanilla wafers into the filling and finish the bars with a light dusting of cinnamon before freezing.
