Place two glasses in the freezer for at least 10 minutes.

Remove from freezer and immediately drizzle both with chocolate Magic Shell sauce along the rim. Let harden for a moment then place back in the freezer while you make the milkshake.

For the chocolate milkshake layer: blend together 4 scoops vanilla ice cream, 1/4 cup chocolate syrup, and 1/2 cup milk in a blender.

Pour into each glass, filling half way.

Now to make the mint milkshake: add 4 scoops vanilla ice cream,  1/2 cup milk, 1/4 tsp mint extract, and 5 drops green food coloring.

Blend in a blender then pour into glasses, on top of the chocolate layer.

Top with whipped cream and sprinkles.

Add a straw and enjoy!
