Mix the chocolate milk and sweetened condensed milk in a large pourable container. Stir until well mixed. Then, stir in the whipped topping, breaking it up with a whisk. Do not worry if small lumps remain. They will be mixed in when the ice cream is churned.
Place the mix in an ice cream freezer and freeze according to the manufacturer's instructions. Serve immediately.
Notes
Substitutes
You can substitute reduced-fat milk for whole milk, which will slightly alter the taste.
Enhancing Chocolate Milk
Not all chocolate milk is created the same; some boast a rich, robust chocolate flavor, while others focus more on sweetness, with varying amounts of sugar.
Sweetness
When preparing an ice cream mixture, it's essential to taste it before placing it in the ice cream freezer. After combining the ingredients, check the mixture for sweetness and chocolate intensity. If the flavor isn't quite right, you can easily enhance it by simply adding 1-2 tablespoons of granulated sugar, stirring until it dissolves, and then tasting again. If additional sweetness is needed, continue to add sugar one tablespoon at a time until you achieve your desired level.
Chocolate Flavor
Similarly, if the chocolate flavor falls flat, incorporatechocolate ice cream syrup, mixing well and tasting until the mixture reaches that perfect balance of sweetness and chocolate richness.
