Who doesn’t like to grab a frappuccino in the afternoon? 

This keto frappuccino is a safe option to fix any craving at home with only 3.8 grams of net carbs and no dairy!

Is Starbucks’ Frappuccino Keto-Friendly?

The standard Coffee Frappuccino from Starbucks contains no less than 46 grams of net carbs per serving.

So it’s not at all a keto-friendly option.

Their frappe contains regular milk and frappuccino syrup (of which the main ingredient is sugar). Most Starbucks drinks are also topped with sweetened whipped cream.

How To Make Keto Frappuccino

It’s very easy to make low-carb frappuccino. The main rule is to use sugar-free ingredients and lactose-free milk to keep it keto-friendly.


The base recipe to make a keto mocha is to combine the following simple ingredients.

  • Brewed coffee – chilled strong coffee is the best but of course, a medium-strength coffee or decaffeinated coffee would be tasty as well.
  • Unsweetened almond milk – I am using unsweetened almond milk as an alternative to dairy milk. It adds a lovely creamy texture to the frappuccino without adding carbs or sugar
  • Cream – I love my drink dairy-free, so I opt for full-fat canned coconut cream making this recipe a delicious paleo frappuccino. However, you can use heavy whipping cream if you prefer, it’s keto-friendly. Both options provide the same texture and macro.
  • Unsweetened cocoa powder
  • Sugar-free Crystal Sweetener – erythritol or monk fruit crystal as you like. Stevia drops are tasty too if you don’t mind the slight bitterness of stevia drops.
  • Vanilla Collagen Powder – keto collagen powder doesn’t add carbs to your drinks. However, it adds healthy collagen, fats, and proteins! You can also stick to just vanilla extract.
  • Ice cubes – the more you add the frothier it will be so always start with a small amount and increase to taste
  • Sugar-free chocolate chips – or use chunks of any dark chocolate with more than 85% cocoa. This is only to decorate the top of your drink and therefore it can be avoided. You can also make your own keto chocolate chips with my recipe.

Prepare a hot coffee a little while before making this keto frappe as you need it to cool down.

You might have to pop your freshly brewed coffee in the fridge or the freezer for it to cool down faster.

To make this recipe, combine all the ingredients in a high-speed blender and blend for about a minute.

Adjust the texture of your iced coffee with more ice for a frothier feel, or more milk to make it runnier.

Serving Keto Frappuccino

It’s up to you to serve this recipe as a grande frappuccino or 2 small frappuccinos.

I personally use the whole recipe as one serving as it only reaches 3.8 grams of net carbs for a 2 1/2 cup size drink.

It’s very comforting to drink such a large sweet drink knowing that it adds so few carbs and calories. While I love ordering a frappuccino at Starbucks, I miss the whipped cream!

Yes, Starbucks’ whipped cream is full of sugar and not recommended on keto. Plus, Starbucks whipped cream is not vegan or paleo.

Therefore, making this healthy mocha frappuccino at home is even tastier! You can add that huge dollop of whipped coconut cream or whipped unsweetened cream to indulge safely!

If you love caramel syrup, you can make my Keto Sugar-Free Caramel Syrup Recipe.

  • Brew coffee at least 1 hour before making the frappuccino. Store brewed coffee in the fridge to chill.
  • In a blender, add the chilled coffee, unsweetened almond milk, coconut cream (or heavy cream), unsweetened cocoa powder, sugar-free sweetener, ice cubes (start with 1 1/2 cup you can add more later for a frothier texture), and collagen protein powder (if you want to use some, optional).
  • Blend on high speed until frosty smooth. Stop the blender and taste. If not sweet enough, this can happen if you didn't add the protein powder, add more sugar-free crystal sweetener (1 or 2 tablespoons). You can also add more ice cubes if you like your frappuccino frothier, up to n extra 1/2 cup. Blend again until it reaches your favorite flavor and texture.
  • Serve immediately as one grande frappuccino (2 1/2 cup drink) or as two small frappuccinos, topped with unsweetened whipped coconut cream and a drizzle of melted sugar-free chocolate.
