Ice Cream in a Bag

Makes about 1 1/2 cups

Who needs an ice cream maker when you can make ice cream in a bag? This time-honored technique really works, plus it's a fun science experiment to do with kids. They can take turns shaking the freezer bag of heavy cream, milk, sugar, salt, and vanilla to make the ice cream. Is it chemistry or magic?


  • 1 cup heavy cream

  • ½ cup milk

  • cup sugar

  • ¼ teaspoon pure vanilla extract

  • 2 ½ pounds ice cubes

  • 2 ½ pounds coarse salt


  1. In a large bowl, whisk together heavy cream, milk, sugar, and vanilla until well combined. Pour mixture into a 1-quart resealable plastic bag. Squeeze out all the air and seal to close.

  2. In another large bowl mix together ice and salt. Fill a 1-gallon resealable plastic bag 1/3 full with ice mixture. Add bag with cream mixture and continue adding ice and salt mixture until bag is filled; you may not need to use all the ice and salt. Seal to close.

  3. Shake bag about 10 minutes until cream mixture is no longer liquid. Let cream mixture rest, covered with ice, another 5 minutes until firm. Serve immediately.
