In a large bowl, pour in the whipping cream and whip until very stiff peaks form.
Using a medium sized bowl, combine the condensed milk and sugar and blend.
Slowly pour the condensed milk mixture into whipped cream while whipping continually.
Pour ice cream mixture into a loaf pan; smooth out.
Scoop out 3 tablespoons of frosting and place them randomly on top of the ice cream mixture.
Using a knife, drag frosting through the ice cream mix, making a swirl pattern.
Using a clean knife, scoop out additional frosting and smooth it on top of the ice cream.
Continue until you’re pleased with how it looks. You can also swirl in sprinkles with the frosting as well.
Embellish with sprinkles and freeze for 6+ hours.
