The flavors of Vietnamese ice coffee come together to form a rich, summertime treat. This no churn recipe doesn't require an ice cream machine; you only need a stand mixer, hand mixer, or a whisk and a strong arm.
Add the cream, condensed milk, and espresso powder to the bowl of a stand mixer or a large mixing bowl.
Whisk until the mixture has the texture of whipped cream. It should hold soft peaks. (Using an electric mixer, this will take about 10 minutes). Stir in the vodka, if using.
Pour the ice cream base into a freezer-safe container, like a loaf pan. Cover with plastic wrap, laying it directly on the ice cream.
