Gather your blender and measuring cup. Pour about a cup of whole milk into the blender; add a splash of peppermint extract.

Let the ice cream soften for about 5 minutes. Scoop out two generous scoops and place them in the blender.

Secure the blender lid and blend at low speed for 10 seconds, then increase to high and blend for another 30 seconds.

Check the consistency; add more milk if too thick, or an extra scoop of ice cream if too thin, blending briefly.

Pour into a chilled glass and serve immediately. Garnish with whipped cream or chocolate shavings if desired.
