Reasons You’ll Love This Recipe:

• High in Protein – one serving provides a whopping 41 grams of protein!
• Two Servings of Vegetables – fresh spinach and frozen cauliflower rice add volume and nutrition, and I promise you can’t taste them!
• Minty Vanilla Flavor – the OG shamrock shake has minty vanilla vibes and they’re fully encapsulated in this healthier copycat.

Ingredient Notes & Substitutions:

For a full ingredient list with quantities, please check out the recipe card at the bottom of this post.

• Greek Yogurt – I use zero added sugar Greek yogurt, but definitely recommend vanilla to enhance the minty vanilla shamrock shake vibes!
• Milk – use any you prefer, but I like to use Fairlife’s ultra-filtered milk for an added boost of protein
• Protein Powder – you need vanilla protein powder, I like Clean Simple Eats.
• Peppermint Extract – a little goes a long way! All you need is 8 drops!
• Spinach – adds some extra nutrients and naturally gives the shake a green color.
• Frozen Cauliflower – another way to add nutrition and volume without negatively impacting the taste.

It couldn’t be easier! Add all ingredients to a blender and blend for 1-2 minutes on high until blended smooth. Serve immediately!

Tips and Variations

• Don’t use too much peppermint extract – I find using peppermint extract as opposed to mint leaves gives more of a shamrock shake vibe, but don’t use too much! Extracts are alcohol based and you’ll be able to pick up on more of those tastes the more you use. 8 drops is perfect!
• Blend long enough to make sure your shake is completely smooth and no weird textures.
• If using whey protein, note that it can sometimes create a “fluffy” texture the longer you blend. If this is something you don’t enjoy, blend everything else first until vegetables are smooth, then add the protein powder for a brief blend.
• Extra ice – for more volume and extra cold, add a cup of ice when blending.
• Add extras – I love blending frozen zucchini slices for extra veg. Avocado can also add some natural green, creaminess, healthy fats, and fiber, too.
