Begin by removing the vanilla ice cream from the freezer and allowing it to soften at room temperature for about 15 minutes.

In a large punch bowl or a sturdy beverage jar, pour in the milk and add the peppermint extract. Use a whisk or spoon to combine them until well blended.

Add the softened vanilla ice cream to the bowl and gently fold it into the milk and peppermint mixture.

Pour in the 7UP around the edges of the bowl just before serving.

Pour the festive drink into glass cups, filling them about three-quarters full.

Provide spoons and straws alongside each glass for a fun and interactive drinking experience.
