How to make Ziploc Bag or Coffee Can ice cream

Hot summer day and the kids won’t leave you alone?  Need a cool treat, that will keep the kids busy… AND tire them out?  Then these recipes are for you!  Here’s how to make coffee can ice cream or Ziploc bag ice cream.  Both are pretty simple and tasty ice cream recipes, but may not fully give Ben and Jerry a run for their money.  What they WILL do is give your kids a tasty treat and keep them busy for a while, and *shhh…*, they may even LEARN something in the process.

Here is what happens:  Ice cream freezes at -6 degrees C.  The freezing point of the water in the can or bag is lowered by the salt that’s been added.  As the temperature drops, the water in the milk freezes, resulting in ice cream.


Recipe from


Vanilla ice cream

  • 1 cup heavy cream
  • 1 cup light cream
  • 1 beaten egg (or use equivalent reconstituted dried)
  • 1/2 cup sugar
  • 1 tsp. vanilla extract


Chocolate Ice Cream

  • 1 cup heavy cream
  • 1 cup light cream
  • 1/2 cup sugar
  • 4 tablespoons cocoa
  • 1/2 tsp. vanilla extract
  • 1/8 tsp. salt



  1. In 1 lb. coffee can mix all ingredients.
  2. The seal can lid well with duct tape.
  3. Put small, sealed can inside larger 3 lb. can. Pack ice and 1 cup of salt around a small can. Put the lid on the large can and duct tape closed.
  4. Roll can, play soccer with it (don’t go too crazy), shake it… basically do ANYTHING to tire your kids out for 15 minutes.
  5. Open the large can and dump ice and water. Wipe small can dry and open.
  6. Stir, ensuring to scrape the sides of the can. Additional ingredients, eg. cookie crumbs, chopped nuts, mini rolls, can be added now.
  7. Reseal a small can and place it back in a larger can. Repack with salt and ice. Continue rolling for 10 minutes more.
  8. Open the large can and dump ice and water. Wipe small can dry and open. Enjoy!


Don’t have coffee cans? Use this great freezer bag recipe from AGintheclassroom!


  • 1/4 cup sugar
  • 1/2 teaspoon vanilla extract
  • 1 cup milk
  • 1 cup whipping cream or half & half
  • Crushed ice (1 bag of ice will freeze 3 bags of ice cream)
  • 1 cup rock salt (approximately 8 cups per 5 lbs.)
  • 1 quart and 1-gallon size Ziploc®
  • Freezer bags
  • Duct tape
  • Bath towel



  1. Put the milk, whipping cream, sugar, and vanilla in a 1-quart freezer bag and seal.  For security, fold a piece of duct tape over the seal.
  2. Place the bag with the ingredients inside a gallon freezer bag.
  3. Pack the larger bag with crushed ice around the smaller bag.
  4. Pour 1 cup of salt evenly over the ice.
  5.  Wrap in a bath towel and shake for 10 minutes.  Open the outer bag and remove the inner bag with the ingredients.  Wipe off the bag to be sure salt water doesn’t get into the ice cream.
  6. Cut the top off and spoon it into cups.

Makes about 3 cups. (1 bag will serve 4).  Serve plain or top with nuts, coconut, or fruit.  ENJOY!
