Wash and slice the ripe peaches, then freeze them for at least 2 hours.

In a blender, combine the frozen peaches, honey or maple syrup, Greek yogurt, ice cubes, and lemon juice. Add vanilla extract if using.

Blend on high speed for 1-2 minutes until smooth and slushy.

Pour into chilled glasses and garnish with mint leaves and peach slices.

Store any leftovers in the freezer, letting them sit out for 5-10 minutes before serving again.
