If you love Thin Mint cookies, you have to try this Thin Mint Protein Shake!

It has all the minty, chocolatey goodness of the classic Girl Scout cookie, but in a healthy, creamy, protein-packed shake that you can enjoy any time of day.

Ingredients Needed

You only need a few simple ingredients to make this Thin Mint protein shake — and I bet you already have most of them on hand!

unsweetened almond milk – I love using almond milk for a light, dairy-free base, but any milk works! Oat, cashew, or regular dairy milk are great options.
frozen banana – adds natural sweetness and makes the shake extra creamy. If you’re not a banana fan, check out the substitutions below!
chocolate protein powder – helps boost the protein while adding rich chocolate flavor. I used Truvani mint chocolate protein powder for extra minty goodness, but any chocolate protein works.
cocoa powder – enhances the deep, chocolatey taste.
peppermint extract – the secret ingredient for that signature Thin Mint flavor! Just a little goes a long way.
ice cubes – helps thicken and chill the smoothie for a refreshing texture.
chocolate chips – adds little bits of chocolate throughout the shake. I used Lily’s chocolate chips for a lower-sugar option. You can also melt some for a drizzle on top!

Variations & Substitutions

There are so many ways to customize this shake to fit your preferences:

Make it extra rich: A spoonful of almond butter or coconut cream takes this shake to the next level with a creamy, decadent texture.
Skip the banana: Use frozen cauliflower rice or avocado for the same creamy texture without the banana flavor. For sweetness, try a Medjool date or a drizzle of maple syrup.
No protein powder on hand? Greek yogurt makes a great alternative, adding protein while keeping things creamy. A little extra cocoa powder enhances the chocolate flavor, and you may want to add honey or maple syrup for sweetness.
Boost the greens: A handful of fresh spinach blends right in without affecting the taste, but adds extra nutrients.

How to Make Thin Mint Protein Shake

Step 1: Add all ingredients, except for the chocolate chips to a blender and blend until smooth. Add chocolate chips & pulse for a few seconds.

Step 2: Pour into a glass. Top with more chocolate chips and/or a melted chocolate drizzle.

Blend in stages: Start by blending everything except the chocolate chips until smooth. Then pulse in the chocolate chips at the end for tiny flecks of chocolate in every sip.
Adjust the mint flavor: Peppermint extract can be strong! Start with ¼ teaspoon and add more if you want a bolder mint flavor.
Make it extra thick: If you love a spoonable shake, reduce the milk slightly or add more ice cubes. You can also blend in a tablespoon of chia seeds or ground flax for a thicker texture.
Add toppings: Feel free to add your favorite toppings! For an extra decadent treat add crushed Thin Mint cookies and/or a drizzle of melted chocolate on top.

How to Store

This mint chocolate protein shake is best enjoyed fresh, but if you need to prep ahead, here’s what to do:

Make ahead: Blend all the ingredients (except the chocolate chips), then store the shake in an airtight container in the fridge for up to 24 hours. Give it a good shake or stir before drinking.
Freezing: For a thicker consistency, freeze the shake in an ice cube tray. When ready to enjoy, blend the frozen cubes with a splash of milk until smooth.
Meal prep tip: Pre-portion the banana, cocoa powder, peppermint extract, and protein powder into a small freezer bag. When you’re ready, just dump it into the blender with ice and almond milk!

Frequently Asked Questions

What’s the best protein powder to use?

A chocolate or mint chocolate protein powder works best for that classic Thin Mint flavor. I used Truvani Mint Chocolate, but any chocolate-based protein will work.

Can I use fresh mint instead of peppermint extract?

Fresh mint can be blended in, but the flavor will be much milder. If using fresh, start with a small handful and adjust to taste.

How can I make this shake thicker?

Use less almond milk, add extra ice, or blend in chia seeds, flaxseeds, or a scoop of Greek yogurt for a thicker, spoonable shake.
