Mint Chocolate Chip Smoothie (Sugar-Free)

Mint chocolate chip was always the flavour I went straight for at the ice cream counter — that cool, sweet mint shot through with little shards of chocolate. This smoothie is my grown-up, low-carb version of exactly that. It’s thick and creamy and properly mint-green, with real cacao nibs running through it as the “chips”, and it tastes like the ice cream I remember — except it’s sugar-free and lands at around 6g net carbs. The clever part is that the green comes from avocado (and a little spinach you’ll never taste), so there’s no food dye and no sugar, just a cool, chocolatey, nostalgic dessert you can drink for breakfast and not feel a thing about it.

What makes it keto

A scoop of mint chocolate chip ice cream is sugar from top to bottom — sweetened cream, syrup and sugary chips. This rebuilds the whole flavour without any of it. The cool mint comes from a few drops of peppermint extract, which has no carbs at all. The chocolate “chips” are cacao nibs — pure crushed cacao beans, naturally sugar-free and full of fibre. The thick, ice-cream-like body comes from avocado and heavy cream, both rich in healthy fat and very low in carbs, and the green is natural too. A keto sweetener brings it up to dessert level. Fat and real cacao instead of sugar — the same treat, made smart.

Ingredients

A handful of things, and the cacao nibs are the magic. Here’s everything, labelled:

The chips: a tablespoon of cacao nibs. Pure, unsweetened chocolate that you pulse in at the end so they stay as little crunchy chips running through the drink.

The cool mint: a few drops of peppermint extract. Potent stuff — a quarter teaspoon is plenty — and the whole reason it reads as “mint chocolate chip”.

The creamy green base: avocado and heavy cream for that thick, ice-cream body, a little spinach for a brighter green if you like, almond milk to blend, and keto sweetener to taste.

How to make it

1. Blend the base first. Pour the almond milk and heavy cream into the blender, then add the avocado, the spinach if using, the peppermint extract and the sweetener.

2. Blend until smooth and green. Add the ice and blend on high for 45–60 seconds, until it’s completely smooth, thick and an even mint green.

3. Pulse in the chips. Add the cacao nibs and pulse just two or three times — you want them broken into little chips, not blended away into the colour.

4. Pour and enjoy. Tip it into a tall glass, scatter a few more nibs on top, and drink it cold and thick, like a spoonable milkshake.

Tips for the best mint chocolate chip smoothie

Add the mint drop by drop: peppermint extract is the one ingredient that can ruin this if you’re heavy-handed. Start with a quarter teaspoon, taste, and add more only if you want it cooler.

Pulse the nibs, don’t blend them: the whole charm is the little chips. Add them last and pulse two or three times so they stay crunchy and visible rather than tinting the whole drink brown.

Spinach for colour, avocado for cream: the spinach is purely for that bright mint-green and adds no flavour you can taste; the avocado is what makes it thick and ice-cream-like. Use both for the full effect.

Freeze the avocado: frozen avocado makes it extra thick and frosty and means you can use a little less ice — a great way to use up avocados before they turn.

Make it your own

• Extra chocolatey: blend a teaspoon of unsweetened cocoa powder into the base for a deeper, fudgier mint-chocolate flavour (and see the chocolate peanut butter smoothie for a full chocolate hit).
• Mint protein shake: add a scoop of chocolate or vanilla keto protein powder to make it a filling post-workout treat.
• Dairy-free: swap the heavy cream for full-fat coconut cream — it works beautifully with mint and chocolate.
• More dessert sips: if you like a pudding-in-a-glass, the berry cheesecake smoothie and the vanilla bean smoothie are worth a look.

A dessert with real chocolate in it

Here’s the nice surprise about going with cacao nibs instead of sugary chips: you’re adding genuine, minimally processed chocolate, which brings real benefits along with the flavour. Cacao is one of the richest sources of flavanol antioxidants there is, and it carries minerals like magnesium and iron plus a good dose of fibre — all the things that get stripped or buried in a sweetened chocolate chip. Healthline has a good rundown of the health benefits of dark chocolate and cacao if you’d like to read more. So while this drinks like an ice-cream-shop treat, the chocolate part is doing you a quiet favour rather than just spiking your sugar — which is exactly the point of a keto dessert.

Who’ll love it

This is for the dessert people — anyone with an after-dinner sweet tooth, anyone who misses mint chocolate chip ice cream on a low-carb diet, and parents looking for a treat the kids will happily drink (the green is natural, the sugar isn’t there). It’s also a fun one if you’re trying to convince a sceptic that keto food can taste indulgent.

Who might want to tweak it: if you find mint “toothpaste-y” or just don’t love it, go very light on the extract or skip this for the vanilla bean smoothie or chocolate peanut butter smoothie instead. And if you want a fruit-forward or refreshing drink rather than a creamy dessert, this rich one won’t be your favourite. But if mint and chocolate are your weakness, this gives you the whole nostalgic treat — antioxidants and all — at about 6g net carbs.

Nutrition (per serving)

Here’s the approximate nutrition for the whole smoothie as one serving. Most of the calories come from the healthy fats in the avocado and cream, while the cacao nibs add fibre and real chocolate flavour for very few net carbs. Values are estimates and will shift with your brand of almond milk and how much sweetener you add.

Mint chocolate chip smoothie FAQ

How many carbs are in this mint chocolate chip smoothie?

As written it comes to roughly 6g net carbs per serving. The avocado and cacao nibs are the only real sources, and both are low-carb and high in fibre, which keeps the net count down. The peppermint extract adds none, the almond milk is unsweetened, and a keto sweetener does the sweetening. A scoop of mint chocolate chip ice cream can carry 25–30g of sugar, so this gives you that same nostalgic flavour for a tiny fraction of the carbs.

What gives it the green colour without food dye?

Two natural things: the avocado, which lends a soft green and a lot of the creaminess, and an optional small handful of baby spinach, which brightens it to that classic mint-green without adding any flavour you can taste. It’s the same trick that makes green smoothies taste un-green — the mint, chocolate and cream completely cover it. If you’d rather skip the spinach, the avocado alone gives a gentler, paler green, which is just as pretty.

Why cacao nibs instead of chocolate chips?

Cacao nibs are simply crushed roasted cacao beans — pure chocolate with no added sugar — so they give you real chocolate ‘chips’ and a lovely crunch while staying keto. Regular chocolate chips are loaded with sugar. If you have sugar-free dark chocolate chips you like, those work too. The key is to add them at the very end and only pulse, so they stay as little chips running through the drink rather than blending into the colour.

It tastes like toothpaste — what did I do?

Almost always too much peppermint extract. Extract is very concentrated, and a little goes a long way — that’s why the recipe says to start with just a quarter teaspoon and taste before adding more. If you’ve overdone it, blend in a splash more almond milk and cream to dilute it, and a little extra sweetener and cacao to push it back toward dessert. Next time, add the mint drop by drop; you can always add more, but you can’t take it out.

Can I make it dairy-free or add protein?

Both are easy. For dairy-free, swap the heavy cream for full-fat coconut cream — it keeps all the richness and pairs well with mint and chocolate. For a more filling drink, add a scoop of chocolate or vanilla keto protein powder, which turns this dessert smoothie into a genuinely satisfying post-workout or breakfast shake. The avocado and cream already make it filling, so even with protein added it stays smooth and creamy.
