No fancy machine or long wait—this ice cream is quick, fun, and doubles as a tasty experiment.

Growing up, I made it in science class, and I remember it being so fun! I just had to share it with my kids. It’s smooth, creamy, and straightforward to change up. It’s smooth, creamy, and straightforward to customize—It is satisfying to vanilla or chocolate, or mix in cookies, caramel, or berries.

And don’t forget the toppings! Once it’s thick and creamy, pile on sprinkles, whipped cream, or hot fudge—whatever you love!

How Does This Ice Cream In A Bag Recipe Work?

Ice Cream in a Bag is a fun little science activity! This method works by lowering the freezing point and tranferring heat:

  • Freezing point lowering: Rock salt makes ice colder by lowering the ice’s melting temp.
  • Heat move: The warm ice cream mix touches the cold salt-ice and starts to freeze.

Shaking helps the mix freeze evenly into soft ice cream in 5–10 mins. For firmer ice cream, freeze for 30 mins—but not longer, or it’ll get too hard.

Supplies Needed

  • Gallon-sized bag: Holds ice and rock salt. Must not leak and should close tightly.
  • Ziploc bag: Holds the ice cream mix. Needs to be leak-proof and seal well.
  • Rock salt: Table salt won’t work the same. Find it in the spice aisle.
  • Ice: Helps freeze the mix. Crushed ice works best; it cools faster than big cubes.
