Ingredients

½ cup salted butter
4 cups mini marshmallows
1 teaspoon vanilla extract
6 cups rice cereal
1 ½ quarts vanilla ice cream

Instructions

Add the butter to a large pot and melt it over medium-low heat. Once fully melted, stir in the marshmallows and vanilla extract. Continue stirring until the marshmallows are completely melted and the mixture is smooth.
Remove the pot from the heat and fold in the Rice Krispies cereal until evenly coated with the marshmallow mixture.
Divide the mixture evenly between two 9x13-inch baking dishes and gently press into an even layer. Let the Rice Krispie layers cool at room temperature for at least 60 minutes before assembling the cake.
About 45 minutes into the cooling time (or 15 minutes before you're ready to assemble the cake), place the ice cream on the counter to soften slightly.
Using a spatula, spread the softened ice cream evenly over the top of one Rice Krispie layer. Carefully loosen the second layer with a knife and place it on top of the ice cream.
Cover and freeze for at least 4 hours before slicing and serving.

Notes

Don’t press too firmly: Light pressure keeps the treats soft instead of dense.
Soften and assemble quickly: Let the ice cream soften just enough to spread easily or risk lifting rice Krispies, then work quickly during assembly so it doesn’t melt too much.
Slice like a pro: Freeze the sandwiches completely before cutting, then use a sharp knife warmed under hot water and dried between slices for clean, neat edges through the frozen layers.
Wrap individually: Perfect for easy grab-and-go frozen treats.
Use fresh mini marshmallows: Mini marshmallows melt faster, measure more accurately, and create softer, chewier Rice Krispie treats than older or larger marshmallows.
