In a large mixing bowl, whip 2 cups of heavy cream on medium speed until stiff peaks form, about 2–3 minutes.

In a separate bowl, mix together 14-ounce can of sweetened condensed milk and 1 teaspoon of vanilla extract until fully combined for about 1 minute.

Gently fold the whipped cream into the condensed milk mixture using a rubber spatula, being careful to keep the airy texture.

Divide the mixture into three bowls. Add pink gel food coloring to one, purple to another, and teal to the last. Stir until the colors are vibrant.

In a loaf pan, scoop alternating dollops of each colored mixture until used up, creating a marbled effect.

Gently swirl through the colored layers in the loaf pan with a knife to blend the colors slightly.

Sprinkle edible glitter or colorful sprinkles on top for decoration.

Cover the loaf pan tightly with plastic wrap and freeze for at least 6 hours, or until firm.
