Top Tip
To help keep your slushy frozen longer, use insulated mugs. You could also freeze some of the slushy base in ice cube trays ahead of time and add them to the drink after it freezes.
Substitutions
- Milk - You do need to use a higher-fat-content milk for this recipe to work. While using 2% should work out okay, the best option is whole milk. If you want to use lower-fat milk, you should replace the water with additional milk.
Variations
- Oreo Chocolate Slushy – Use black cocoa powder and then garnish with crushed Oreo cookies.
- Mocha Slushy – Swap strong coffee in for the water or add 1 teaspoon instant espresso powder for an amazing frozen mocha slushy.
- Peppermint Hot Chocolate Slushy – Add a few drops of peppermint extract. This is a favorite flavor in my house.
- Chocolate Strawberry Slushy – Add ¼ cup strawberry syrup.
