Making Chocolate Ice Cream Recipe in a Bag

If you have cream in your refrigerator, it’s time to transform that into delicious ice cream. This is also an awesome way to learn the melting point of ice.

All three of my kids looked at me sideways when I added salt to the bag of ice. This was the perfect time to talk about the freezing point of ice and how we get ice cream from doing so.

What you need:

  • 1 gallon Ziploc bag
  • 1 sandwich bag
  • 1 tbsp white sugar
  • 2 tbsp hot chocolate mix (you could also use cocoa powder)
  • 1/2 cup of whipping cream
  • 1/3 cup of coarse salt
  • ice cubes

Let’s Shake Ice Cream

In your sandwich bag mix together the whipping cream, sugar, and hot chocolate mix. Seal the bag, letting out as much air as possible.

In your large bag, fill it with 2 trays worth of ice cream and 1/3 cup of salt. Add your sealed sandwich bag and seal it, getting most of the air out of the bag.

Now shake. Shake for about five minutes. We used oven mitts because it gets quite cold on your hands after a minute.

After shaking for five minutes put it in your freezer for half an hour.

After half an hour in the freeze, scrap/shake your soft serve ice cream into a bowl. Top with some sprinkles, or chocolate syrup, and enjoy. There is nothing like a little ice magic to make a yummy summer snack.

Science Behind Ice Cream in a Bag

Salt when added to the ice cubes lowers the melting point of the ice, just like it does when we add salt to roads in the winter. In order for the ice to melt, however, it has to absorb heat from its surroundings like the ice cream in the bag.

The ice pulls the heat away from the cream which allows the cream to freeze and become ice cream.

If you made this with ice cream without salt you would notice that the ice cubes do not melt as much in the five minutes of shaking and you would notice that the cream is not becoming solid and turning into ice cream.

Tips & Tricks for Making Your Snack

Alternately you could make this ice cream with some chocolate syrup in the bag to make chocolate ice cream, which I had planned to do, but forgot to buy the chocolate syrup. Or strawberry syrup.

Make sure you do up the small bag first so you don’t have melted ice cubes when you add them to the large bag.

If you suspect your child will drop the bag, double up the large bag, it will easily get holes when dropped – even the brand name bags. Plus, not quite as cold on the fingers.
