In a large mixing bowl, pour in 2 cups of heavy whipping cream. Beat on medium-high speed for about 3-5 minutes until stiff peaks form.

In a separate bowl, combine 14 ounces of sweetened condensed milk with 1 teaspoon of vanilla extract. Gently fold this mixture into the whipped cream.

Divide the creamy mixture into three smaller bowls. Add drops of different pastel food coloring gels to each bowl and stir gently.

Prepare a 9-inch loaf pan. Layer the ice cream mixture in the pan, alternating colors until all mixtures are used.

Using a toothpick, gently swirl through the layered mixtures to create a soft marble effect.

Sprinkle decorative mermaid sprinkles on top. Cover with plastic wrap and freeze for a minimum of 6 hours or overnight.
