Add the egg whites, sugar, directly to a Ninja Creami Deluxe pint container. Mix with mini milk frother (mini immerison blender) just until sugar crystals mix in.
¼ Cup Egg Whites, ¼ Cup White Sugar
Add the half and half with the vanilla mix again.
1 Cup Half and Half Cream, 2½ Tbsp Clear Vanilla Extract
Top with the 3.25 milk cover with pint lid before freezing.
1 Cup 3.25% Milk
Freeze for 24 Hrs.
Remove the frozen pint from the freezer and place it into the Ninja Creami Deluxe outer bowl according to the manufacturer's instructions.
Install the bowl in the machine and process using the Ice Cream setting.
After the first spin, check the texture. If the mixture presses together easily with a spoon, it may already be ready to scoop.
If the ice cream appears loose, dry, or powdery, run a respin.
If adding mix-ins such as chocolate chips, cookie pieces, fruit, or candy, create a small well in the center of the ice cream, add the mix-ins, and use the Mix-In setting. In most cases, there is no need to run a respin before using the Mix-In function.
Serve immediately for a classic ice cream consistency.
