Vanilla Ice Cream: I used dairy-free vanilla ice cream to keep this recipe vegan and gluten-free. If you are not vegan or lactose-intolerant, feel free to use normal vanilla ice cream instead.

Coconut Milk: I used full-fat coconut milk to keep this recipe dairy-free. If you are not lactose-intolerant, feel free to use normal whole milk instead.

Vanilla Extract: Vanilla extract adds extra vanilla flavor to the shake. If you are Celiac or gluten-intolerant, make sure to use gluten-free vanilla extract.

Mint Extract: Make sure to use mint extract and NOT peppermint extract, it resembles the flavor of the McDonald’s shamrock shake more. If you are Celiac or gluten-intolerant, make sure to use gluten-free mint extract.

Green Food Dye: The green food dye is a key component in this copycat shamrock shake recipe to give the shake its characteristic green color. If you are Celiac or gluten-intolerant, make sure to use gluten-free green food dye.

Whipped Cream: I used dairy-free whipped cream to keep this recipe vegan and dairy-free, but if you are not vegan or lactose-intolerant, you can use normal whipped cream instead.

Green Sanding Sugar: Sprinkling a little green sanding sugar makes this dairy-free Shamrock shake a little more festive.
