keto frappuccino

I love Starbucks, but ever since going keto, I’ve decided to reign in my Starbucks addiction and start making my favorite drinks at home.

These low-carb frappucinos are a game changer. With no sugar, no dairy, and almost zero carbs, you’d never be able to tell. The texture is thick and creamy, and it has a rich coffee flavor that’s easy to customize with a little sugar-free syrup, whipped cream, you name it.

Why I love this recipe

  • Made in seconds. Just add everything to your blender and blend away. It’s that simple. 
  • Easy to customize. Add your favorite sugar-free sweeteners and syrups, or add an assortment of toppings. The options are limitless. 
  • WAY cheaper than Starbucks. A classic frappe will set you back at least $5, but this one is well under a quarter of that. 
  • 1 gram of net carbs. Compared to over 50 grams of carbs in a regular Starbucks frappuccino!

Ingredients needed

  • Milk of choice– Any milk of choice can be used. Alternatively, for a richer flavor, use half and half or add some heavy cream. 
  • Espresso OR instant coffee– If you own a coffee machine or espresso machine, it’s best to use freshly brewed espresso. You want to use 1 serving of espresso per frappuccino. If you don’t have a coffee machine, you can use instant coffee. 1 tablespoon of coffee mixed with 1 tablespoon hot water. 
  • Ice– The smaller your ice cubes, the more smooth and blended your frappuccino will be. 
  • Sweetener of choice– Either monk fruit sweetener or allulose can be used. 
  • Whipped cream– Optional, but what is a keto frappe without keto whipped cream?
  • Caramel– Again, optional, but I love drizzling some keto caramel over the top. 

How to make a keto frappuccino at home

I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.

Step 1- Combine the ingredients. In a high-speed blender, add all of the ingredients except for the whipped cream and caramel and blend until smooth.

Step 2- Serve. Transfer to two tall glasses, top with whipped cream, and drizzle with caramel sauce.

Flavor Variations

While I like to stick to the classic coffee frappuccino, you can easily change up the flavors to some of Starbucks’ most popular flavors. Each of these would still be low carb and have less than 2 grams net carbs per beverage

  • Peppermint mocha– Add 1-2 drops of peppermint extract to the blender. Swap out the caramel for a sugar free chocolate sauce. 
  • Java Chip– Increase the espresso to double the amount. 
  • Chocolate mocha- Drizzle sugar free chocolate syrup and add 1 tablespoon cocoa powder. 
  • White chocolate– Add 1-2 drops white chocolate extract. 
  • Mocha cookie crumble– Add 1-2 homemade Oreos to the blender and sprinkle with extra crushed up cookies on top;
  • Pumpkin spice– Add 1-2 tablespoons pumpkin puree and 1 tablespoon pumpkin spice. 

How to store leftovers

To store: I highly suggest making your frappuccino fresh and enjoying it promptly, but if you have any leftovers, you can store them in an airtight container in the fridge for up to 1-2 days. Make sure to re-mix it before enjoying as it’ll separate over time. 

To freeze: Pour the frappuccino into an ice cube tray and freeze the ice cubes. Store the cubes in a freezer-safe container for up to 1 month, then add them to a blender with a splash of coffee or milk and re-blend until it reaches your desired consistency.

Frequently asked questions

Can I use decaf coffee?

Yes, if you have an intolerance to caffeine, you can use decaffeinated espresso or instant coffee.

  1. Also, if you have a problem with the drinks getting watery too fast, a tiny bit each of Lecithin and Xanthan gum will hold it together and do the trick. Just use very, very little and add a tiny bit in subsequent times until you find the right mix (don’t try on the batch, xanthan gum can take a minute to thicken up and it’s easy to add more before it’s fully set up and get too much.)
