Refreshing frozen treats are a summer staple, but we all know they can (and should!) be enjoyed year-round. Give your oven a rest and let your freezer do most of the work when you make this easy layered ice cream cake or these healthy 3-ingredient strawberry banana popsicles. No ice cream maker is required for this no-churn blueberry crumble ice cream, and everyone loves these cookie ice cream sandwiches, too!
