Pour the milk, almond milk, allulose, pudding mix, peppermint extract, and food coloring into a small blender and blend until all ingredients are fully combined. Pour the mixture into a Ninja Creami container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit.
Process the Ice Cream
After 24 hours, remove the Ninja Creami container from the freezer. If there is a large bump in the ice cream, melt or scrape the large bump so that the top is level.
Place the Ninja Creami container into the outer bowl of the Ninja Creami and then process on "ICE CREAM."
If the ice cream is dry or crumbly looking (like sand), pour in a tablespoon or two of milk and then re-spin. If the ice cream looks more like little balls of ice cream, re-spin without adding liquid. You may have to respin a couple of times.
Dig a well down the center of the ice cream, pour in the crushed mints, and process on "MIX-INS."

Notes
Can mint or spearmint extract be used instead of peppermint?No, you can’t substitute those for the peppermint extract unless you want the ice cream to taste like toothpaste. Peppermint extract is minty but not overwhelmingly minty like toothpaste.Can you use candy canes in the ice cream instead of starlight mints?You sure can! Candy canes would make this recipe perfect for the winter holidays.Do you have to use the red food coloring?No, you don’t need to use the food coloring if you don’t want to. The food coloring doesn’t add any flavor or change the texture. It just changes the color. You can skip it altogether if you prefer, or you can use a different color.
