01 -
Place 2 tall milkshake glasses in the freezer for 5-10 minutes while you gather the ingredients.
02 -
Add lime sherbet, vanilla ice cream, whole milk, and green gel food coloring to a blender. Blend until smooth and bright green.
03 -
If the shake is too thick for the blender, add milk 1 tablespoon at a time. Keep it thick enough to mound slightly in the glass.
04 -
Divide the milkshake between the chilled glasses, leaving about 1 inch of space at the top for whipped cream.
05 -
Top each glass with whipped cream, purple and green sprinkles, black sprinkles, and candy eyes. Serve immediately.
