This Keto frappuccino is an easy DIY low-carb chocolate coffee milkshake with almond milk. Bonus, one Grande Frappuccino only contains 3.8 grams of net carbs to indulge without guilt!

Who is craving a frappuccino in the afternoon?  I do crave Starbucks chocolate frappuccinos all the time. So this keto frappuccino is my safe option to fix my craving at home with only 3.8 g net carbs and no dairy!

How to make a 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 chocolate keto frappuccino 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 too
  • Unsweetened almond milk – I am using the unsweetened almond 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 too. However, you can use heavy cream if you prefer. Both options provide the same texture and macro.
  • Unsweetened cocoa powder
  • Sugar-free crystal sweetened – 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 protein collagen powder – keto collagen powder doesn’t add carbs to your drinks. However, it adds healthy collagen, fats, and proteins!
  • 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.

What are the benefits of collagen powder?

This healthy frappuccino is boosted with vanilla protein collagen powder.  Keto collagen powder won’t add carbs to your drink. However, it’s a great addition to reinforce bones, joints, and skin on a keto diet.

Plus, it also adds as much as 25g of protein to your drink which is amazing to reload protein after a workout. If you don’t feel like using protein powder, the recipe would be as delicious, it would simply contain less protein.

Grande frappuccino or two small collagen drinks to share!

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 frappuccino at home is even tastier! You can add that huge dollop of whipped coconut cream or whipped unsweetened cream to indulge safely!

  • 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.
