While McDonald’s shamrock shake is gluten-free, you can also make them at home. Instead of using vanilla ice cream, green food coloring, and chocolate syrup, I took a shortcut, making it that much easier!
If you use Breyer’s mint chip ice cream, it is natural; therefore contains no green coloring. You’ll need to add some gluten free food coloring. I have homemade green recipe and commercial brands listed here.
