Combine the Fairlife chocolate milk and unsweetened almond milk in the Ninja Creami pint to the max fill line. Add chocolate protein powder and sugar-free chocolate jello mix. Blend until thoroughly smooth using a handheld frother.

Cover the pint and place it in the freezer. Allow it to freeze completely for 24 hours until solid.

After 24 hours, run the pint under hot water for about 60 seconds to loosen the ice cream.

Install the pint into the Ninja Creami machine and select the 'Lite Ice Cream' button. Let the machine process until the desired smooth consistency is reached.

If the ice cream is too thick or powdery, add a splash of almond milk and respin until the texture is smooth.

Gently fold in the rainbow chips and sprinkle in some chocolate chips, pressing the mix-in button on the Ninja Creami to incorporate.

Scoop the Cosmic Brownie Protein Ice Cream into bowls and top with extra rainbow chips before serving.
