For Ice Cream
In a medium sized mixing bowl add heavy whipping cream and use a hand mixer or standing mixer on medium-high speed. Whip heavy cream together until stiff peaks begin to form. (about 5-7 minutes)
In another mixing bowl, combine sweetened condensed milk, vanilla and salt. Mix until combined
Fold in condensed milk mixture to the whipped cream
Add cream mixture into a loaf pan, and swirl cinnamon sugar into the vanilla ice cream. Use a toothpick or knife to make the marble effect by dragging it throughout the pan
Cover with plastic wrap and foil. Allow to freeze at least 6 hours or overnight
Serve in a bowl or on your favorite cone.
Notes
NOTE- Keep in an airtight container. Ice cream will last about 2 weeks. Probably sooner because EVERYONE is going to love it!
