Add all "Ice Cream Base" ingredients to a blender and blend until smooth.
Pour the mixture into a Ninja Creami pint and freeze on a level surface for 24 hours.
Remove from the freezer, rinse the pint under hot water for 1-2 minutes.
Spin on Lite Ice Cream mode.
Respin 1-2 times until creamy.
Create a well in the center and add 4 of the Oreo cookie halves. Spin on Mix-In mode.
Crush the remaining 2 Oreo cookie pieces over the top. Then add 3 gingerbread men as the final decoration.
Optional: Stick one candle between each gingerbread man for the full Krampus fantasy and enjoy!
