This all natural keto Shamrock Shake recipe is a festive drink to enjoy on Saint Patrick's Day. But it's also a great homemade low-carb mint milkshake to enjoy year-round.
When I was younger, I used to always look out for when McDonald's started selling their minty green shake around St. Patrick's Day. There was always something about the "Limited Time Only" slogan that made you feel like this may be your last chance to have one.
Although sold as a drink, I could never sip them with a straw because they were so thick from the soft serve ice cream used to make them. Of course I would never touch one of these shakes today since I stay away from sugar and artificial ingredients.
The shake is made using two ingredients: McDonald's vanilla soft serve ice cream and a sweet green mint syrup. Both of these ingredients contain sugar and corn syrup which aren't keto friendly.
That's why I came up with homemade Shamrock Shake recipe made with low-carb ingredients. It has a similar taste and texture with just 3g net carbs.
There's only three essential ingredients for the recipe: low-carb vanilla ice cream, mint extract, and unsweetened almond milk. To get the optional green color, you can use either natural food dye or spinach powder.
I had some no churn keto ice cream in the freezer which made this a quick and easy treat to make. You could use store bought low-carb ice cream, but one made with artificial sweeteners wouldn't result in an all-natural shake.
I used two small scoops of vanilla ice cream that is probably around ½ a cup packed. I wanted the shake to be thick, but thin enough that it could be sipped with a straw.
Making a Homemade Shamrock Shake
Here's how to make a thick milkshake quickly at home with ice cream, milk, extract flavoring, and natural food dye.
All you have to do is combine all the ingredients with a blender then pour into a tall glass. Topping it with sugar-free whipped cream is optional.
You can easily make the keto Shamrock Shake recipe in less than two minutes. That's faster than going through a fast food drive-thru window!
My favorite way to change it up is to drizzle sugar-free chocolate syrup on top of the whipped cream. But you can also blend the syrup in with the other ingredients.
