I'm not going to beat around the bush here. I love Shamrock Shakes. of course when you have a family of 5, those trips to McDonald's can get to be a bit pricey. Which makes me so happy that I know hoe to make them at home with just one extra ingredient.
Simply add a bit of Creme de Menthe syrup (I use Torani) with the milk & vanilla ice cream. That's it! A little does go a long way, so trying to get that same green color will most likely be too minty for you. But even though it may not be as green, it still tastes just the same. If not better!
