There are many simple ingredients you will find in ice cream recipes. And those ingredients differ depending on if it's churn ice cream recipes or no-churn. But for your typical sweet cream ice cream base or vanilla ice cream recipe, you will find heavy whipping cream, whole milk, and egg yolks for an egg custard base. For Philadelphia style ice cream, there is no egg yolk. There is also a way to make ice cream no-churn. It requires condensed milk and a hand mixer.
