Homemade Root Beer Float with Ice Cream…in a Bag!

I saw ice cream rock salt at birch and immediately knew my kids needed to make ice cream in a bag! This simple recipe uses just a few pantry staples, a gallon bag, ice, and rock salt to create creamy homemade vanilla ice cream. Top it with soda for a classic summer treat that’s fun for kids and adults alike.

What You’ll Need

Ice Cream

• 1 cup half-and-half (or whole milk for a lighter version)

• 2 tablespoons sugar

• 1 teaspoon vanilla extract

• Pinch of salt

For the Ice Bath

• 1 gallon-size zip-top bag

• 1 quart-size zip-top bag

• 4 cups ice

• ½ cup rock salt

For the Float

• Root beer (or your favorite soda)

How to Make It

1. In a quart-size zip-top bag, combine the half-and-half, sugar, vanilla, and salt. Seal tightly, removing as much air as possible. For extra protection against leaks, place it inside a second quart-size bag.

2. Fill the gallon-size bag halfway with ice and sprinkle in the rock salt.

3. Place the sealed ice cream bag inside the ice bag. Seal the gallon bag tightly.

4. Wrap the bag in a towel and shake for 8–12 minutes, or until the mixture reaches a soft-serve consistency.

5. Remove the small bag, rinse and dry the outside before opening.

6. Scoop the homemade vanilla ice cream into a glass and slowly pour root beer over the top until it becomes frothy. Serve immediately with a spoon and a straw if desired.
