Step 1

Combine 1 tsp vanilla extract, 1/3 cup granulated sugar, 1 cup 2% milk, 3/4 cup heavy cream, 2 egg yolks, 1/4 cup cake mix, and a dash of salt in a pot and cook on the stove at medium heat for 5 minutes, whisking constantly. This will ensure the eggs will not be scrambled.

Step 2

Pour the mixture into a Ninja Creami pint container, ensuring it does not go over the max fill line.

Step 3

Wait for the pint to cool, then place it into the freezer (ensuring it is on a flat surface). Freeze for 24 hours.

Step 4

After 24 hours, remove the pint from the freezer, and plug in your Ninja Creami machine! Time for the magic.Remove the lid from the pint and grab the Ninja Creami outer bowl. Place the pint securely into the outer bowl and cover with the lid. Once the lid is on, place the outer bowl into the machine, twisting to the right until it locks into place. Press the "Gelato" button and (try to) wait patiently for the creamy treat coming your way.

Step 5

Once the process is finished, press and hold the button on the left side of the Creami to twist the bowl to the left and remove it from the machine. Twist the lid off of the outer bowl and remove the pint.

Step 6

Top off the cake batter gelato with some rainbow sprinkles and enjoy!
