Why you’ll love this recipe:

If you love those Rice Krispie ice cream sandwiches from the grocery store freezer aisle, you’re going to love this homemade version even more. These Rice Krispie Ice Cream Sandwiches are made with soft, chewy homemade Rice Krispie treats packed with mini marshmallows and layered with creamy vanilla ice cream. Once frozen and sliced into bars, they’re the perfect summer dessert!

What makes these homemade Rice Krispie ice cream sandwiches so special is the texture. The Rice Krispie treats stay soft and chewy while the vanilla ice cream adds a creamy, refreshing layer in the middle. Every bite is buttery, marshmallow-filled, and perfectly cold, making them one of the best frozen treats to enjoy on a hot day.

Ingredients you’ll need:

Mini marshmallows- divided
Butter
Vanilla extract
Rice Krispies cereal
Vanilla ice cream

One of the best things about this recipe is how easy it is to make. There’s no need to churn homemade ice cream or spend hours in the kitchen. A container of store-bought vanilla ice cream works perfectly, which means you can put these together with minimal effort. They’re simple enough for a weekday treat but fun enough to serve at birthday parties, cookouts, and summer gatherings.

These Rice Krispie Ice Cream Sandwiches are also a homemade version of the classic store-bought treat many people grew up eating. If you’ve ever wished those freezer-section sandwiches had more marshmallow flavor, a softer texture, or a thicker layer of ice cream, this recipe delivers exactly that. Homemade always tastes fresher, and you get complete control over the ingredients.

The flavor is everything you love about a classic Rice Krispie treat combined with smooth vanilla ice cream. The buttery marshmallow cereal bars add sweetness and chewiness while the ice cream keeps every bite cool and creamy. It’s a simple combination, but one that never gets old!

How to make the best Rice Krispie Ice Cream Sandwiches:

Line two 9×9 inch pans with parchment paper, leaving an overhang, then set aside.
In a large pot, combine 8 cups mini marshmallows with butter. Melt over medium-low heat, stirring continuously, then remove from the heat and stir in the vanilla extract.
Stir in the Rice Krispies, then fold in the remaining two cups of mini marshmallows.
Divide the Rice Krispie treat mixture evenly between both prepared pans and gently press them into an even layer. Lightly spray your hands with cooking spray if needed to prevent sticking.
Let both pans cool at room temperature for 30 minutes.
Scoop a 1 inch layer of ice cream over one pan of treats and spread it into an even layer.
Lift the second block of treats out of the pan using the parchment paper, flip it over and place it on top of the treats with the ice cream layer.
Press down firmly and evenly, then peel off the parchment and freeze until solid, about 4-6 hours.
Use the parchment to lift the treats onto a cutting board, then cut into equal sized bars. If the treats are too hard, let sit at room temperature for 5–10 minutes.
Return any extras to the freezer to prevent melting.

Another reason to love this recipe is how customizable it is. Vanilla ice cream is a classic choice, but almost any flavor works. Chocolate, cookies and cream, strawberry, birthday cake, or mint chocolate chip can completely change the personality of the dessert. You can even add sprinkles, chocolate chips, or extra mini marshmallows to the Rice Krispie layers for even more flavor and texture.

These frozen Rice Krispie treats are especially perfect during the warm weather months. Since they can be made ahead of time and stored in the freezer, they’re always ready whenever a dessert craving strikes. They also make serving a crowd easy, and offer a refreshing alternative to traditional baked desserts.

If you’re looking for an easy summer dessert that’s nostalgic, family-friendly, and guaranteed to disappear quickly, these Rice Krispie Ice Cream Sandwiches are hard to beat. They’re everything people love about classic Rice Krispie treats and ice cream combined into one simple frozen dessert. After one bite, you may never go back to the store-bought version again!

My top tips:

LINE YOUR PAN: It’s important to line your baking pans with parchment paper or wax paper to prevent any sticking. These treats have a lot of marshmallows in them and are very chewy – if you don’t line your pan they will stick.
WORK WITH LOW HEAT: Make sure your heat is set to medium-low when melting down the butter and marshmallows. Doing this step slowly, and stirring continuously, will ensure that nothing burns, and your finished product will be super soft and chewy!
RICE KRISPIES: Use plain Rice Krispies like I did or switch it up with cocoa krispies or fruity pebbles for a fun twist!
PRESSING INTO THE PANS: The Rice Krispie treat mixture is very sticky and can be hard to spread with a spatula. I recommend lightly wetting or greasing your fingertips, or a square of parchment paper, and using that to gently press the mixture into the pan to avoid a sticky mess.
COOLING: The Rice Krispie treats have to cool before assembling the ice cream sandwiches so the residual heat doesn’t melt the ice cream layer. If the Rice Krispies are too warm when you add the ice cream, it will turn into a sticky, messy soup and ruin the structural shape of your sandwiches.
ICE CREAM FLAVORS: Easily swap vanilla ice cream for chocolate, cookies and cream, or strawberry. If your ice cream is extra firm, I recommend placing it in the fridge for about 15 minutes to help soften it before scooping to make it easier to spread.
WORK QUICKLY: Ice cream melts fast! Make sure you have a sharp knife ready to cut the frozen ice cream sandwiches into bars, then be sure to return any extras to the freezer to prevent melting.
STORING: Wrap each Rice Krispie Ice Cream Sandwich tightly in plastic wrap or foil then store in the freezer and enjoy within a week for the best flavor and texture.
