Step 1

Pour one cup of cream and 1 cup of the dulce de leche into a saucepan with the sugar and whisk gently over low heat just until the sugar is fully dissolved. Add the remaining heavy cream, milk, salt, and vanilla and whisk to combine. Refrigerate for at least one hour, or until very well chilled, but up to overnight.

Step 2

Freeze in your ice cream maker according to manufacturer's instructions. When the ice cream is done churning, dollop by tablespoons and swirl in the remaining 1/2 cup dulce de leche. Transfer to a freezer safe container and freeze for at least two hours or until firm.
