Keto Shamrock Shake (Low Carb and Sugar-Free Copycat!)

This post may contain affiliate links. Please read my full disclosures here.

Finally, a healthy keto shamrock shake recipe! I’m sharing my favorite copycat keto dessert. Homemade and easy, this is a perfect St Patrick’s Day DIY with kids (without all that added sugar). With options for dairy-free and additional protein too.

Do you head straight for the McDonald’s drive-thru every March?! Even though I know how awful McDonald’s Shamrock Shakes are for my health, I can’t help but miss them terribly!

But here’s the thing – not only can you make a sugar-free Shamrock Shake at home that’s way healthier, but it’s also WAY more delicious and super easy.

And don’t worry, I’m not going to tell you to use avocado or spinach.  Because while those things would definitely have their place in a festive low carb St Patrick’s Day green veggie smoothie, they don’t belong in my Shamrock Shake.  Sorry, not sorry.

The Best Ice Cream For Keto Shamrock Shakes

Rebel Ice Cream makes the best commercially available keto ice cream.  My local grocery store just started carrying it, and it’s been incredibly popular.

But what if you haven’t seen it in a store near you? You can actually order it on Amazon and have it shipped. What a time to be alive.

And if you’re thinking it’s crazy to order ice cream online, I totally get it.  But don’t worry, Rebel packs each order in a cooler with dry ice so your ice cream will be frozen solid when it arrives. PS – shipping cost will be a happy surprise (I couldn’t believe it!).

Rebel currently makes eight flavors:

  • Vanilla
  • Chocolate
  • Mint Chip
  • Cookie Dough
  • Peanut Butter Fudge
  • Strawberry
  • Butter Pecan
  • Coffee Chip

Can I make This Into A Healthy Keto Breakfast for St Patrick’s Day?

If I’m being honest, I’m always looking for ways to add in more nutrition, even when I’m having a treat like this. But recently I’ve been binge-consuming Chris Masterjohn’s content, including his Nutritional Status Ultimate Cheat Sheet. At 82 pages, it’s probably the cheapest, clearest, and most useful resource I’ve bought on the internet in a LONG time!

If you have any combination of MTHFR and you’ve previously felt bogged down by information overwhelm, you won’t find a better or simpler guide anywhere. I HIGHLY recommend it.

Here are a few things that I added to my Shamrock Shake to boost my own personal nutritional status:

So feel free to turn this into a St Patrick’s Day keto protein shake recipe!

How To Make Variations Of This Keto Milkshake Recipe

Keto Vanilla Milkshake: Just leave out the mint extract! Optionally, add ¼-1/2 tsp vanilla extra to amp up that vanilla flavor.

Thin Mint Keto Milkshake: Use Rebel’s chocolate keto ice cream instead of vanilla in this keto-friendly Shamrock Shake recipe and you’ve got a keto Thin Mint milkshake!

Using Peppermint Extract vs Mint Extract vs Essential Oils

To replicate that minty delicious Shamrock Shake flavor accurately, use pure mint extract (like this one made by Frontier Co-op), not peppermint extract.

What’s the difference between mint extract and peppermint extract? Pure mint extract is a combination of both spearmint and peppermint. So while peppermint extract is much more common, it will make your shake candy cane flavor instead (obviously still delicious if that’s what you’ve got on hand!). Pure mint extract, on the other hand, will make your keto Shamrock Shake taste just like the real thing!

What about essential oils? Food grade essential oils will also work. Try adding equal parts of peppermint and spearmint essential oils to taste. Start with just one drop of each – a little goes a very long way!

Can I Use Heavy Cream To Make A Keto Milkshake?

If you only have heavy cream handy you can use it in place of the half and half!  Since heavy cream is thicker, I suggest using half heavy cream and half filtered water so the mixture will be blendable.

Can I Make A Dairy-Free Keto Shamrock Shake Milkshake?

To make a dairy-free keto shamrock shake, you could substitute low carb, plant-based Wink Ice Cream. There may be other low carb, dairy-free vanilla ice cream products available in your area that I don’t have in my grocery store – I suggest checking your local natural foods store or Whole Foods.

Use your favorite low carb, dairy-free milk in place of the half and half.  I suggest keeping it simple with full-fat coconut milk or plain unsweetened almond milk. Always remember to check the nutrition label on non-dairy milks. So many of them are loaded with added sugar.
