How to Make a Keto Mocha Frappuccino

Homemade Keto Mocha Frappuccino Recipe
This low-carb recipe is for you if you are a fan of the Starbucks Dark Chocolate Mocha Frappuccino, but you can’t have it because of its high carbohydrate content.

In this post, you will find out how to make a delicious Keto Mocha Frappuccino at home. This homemade frozen drink is sweet, has a nice cacao flavor, and contains only 2 net carbs per serving.

If you’re on a keto diet and you’re looking for a way to make a mocha bulletproof coffee, then you should definitely DIY this coffee frappe.

Without further ado, let’s continue with the recipe ingredients.

Keto Mocha Frappuccino Ingredients

Here are the ingredients that you’re going to need to make a Keto Mocha Frappuccino:

  • Espresso – double espresso shot (or 2 teaspoons of instant coffee).

    At Starbucks, Frappuccinos are usually made with something called Frappuccino Roast (Frap Roast). Frap Roast is instant coffee dissolved in room temperature water.

    When preparing your coffee Frappuccino, a Starbucks barista usually adds a few pumps of Frap Roast to the blender. This is the recipe component that adds caffeine to your drink.

    Unlike a freshly pulled espresso shot, the Frappuccino Roast isn’t hot and it doesn’t compromise the frozen texture of your iced blended drink.

    So if you don’t have an espresso machine, or you want to make sure that the ice cubes won’t melt after you add the hot espresso, feel free to use 2 teaspoons of instant coffee powder instead of hot coffee.

    With that being said, if I am to use espresso for my homemade Frappuccino, I always add a double shot (2 fl. oz. or around 60 ml). I prefer my bulletproof coffee strong. Nevertheless, if you want to lower the caffeine content of your dark chocolate mocha Frappuccino, use a single shot of espresso, or just one teaspoon of instant coffee powder.
  • Unsweetened Almond Milk – 4 fl. oz. (120 ml).

    Unsweetened almond milk contains 1 carbohydrate per 8 fl. oz. serving. You only need 4 fl. oz. or 120 ml to make a keto mocha Frappuccino at home.

    In case you want your Frappuccino thicker and creamier, feel free to use 3 fl. oz. (90 ml) of full-fat canned coconut milk. If you decide to do so, keep in mind that 3 fl. oz. of coconut milk contains around 2 grams of carbs. So by substituting the almond milk with coconut milk, you will increase the number of carbs your mocha contains.

    Instead of substituting the almond milk with full-fat canned coconut milk, I prefer topping off my homemade chocolate Frappuccino with a bit of whipped coconut cream. A heaping tablespoon weighs around 20 grams or 0.7 oz. (and contains less than 1 gram of carbs). It adds the right amount of creaminess to my cool coffee drink.

    If you’re not a fan of the coconut flavor, and you don’t want to use heavy cream in the making of your frappe, but you still want to make your keto-friendly Frappuccino thicker, add a quarter of a teaspoon of xanthan gum to the mixture before blending. Xanthan gum is a thickening agent that will bring your blended coffee drink closer to the original Starbucks version.
  • Cacao Powder – 1 heaping teaspoon.

    One heaping teaspoon of cacao powder weighs around 5 grams and contains 1.5 net carbs.

    I recommend using cacao, not cocoa powder as the former contains more antioxidants. For this recipe, I used organic cacao powder by Terrasoul (check it out on Amazon by clicking here).
  • Liquid Stevia/Erythritol (or both).

    To sweeten your keto mocha Frappuccino you can use 3 to 5 drops of liquid stevia or 1 tablespoon of erythritol.

    I’ve found that using 2-3 drops of liquid stevia and 1 teaspoon of erythritol works best tastewise. Used in combination, these keto-friendly sweeteners complement each other’s flavors nicely. By combining them the drink taste as if it’s sweetened with regular sugar.

    Another way to sweeten your keto coffee is by using a keto-friendly coffee syrup. You can check out a list of the best low-carb sugar-free syrups by clicking here.
  • MCT Oil – 1 teaspoon.

    I don’t always add MCT oil when I make my keto chocolate frappe. I do so when and I feel like having a satiating bulletproof mocha Frappuccino that will keep me full and provide me with energy for a longer period.

    If you’ve been on e ketogenic diet for a while and your body is used to processing the bulletproof coffee’s basic ingredients, you can add a whole tablespoon of MCT oil. Furthermore, you might even want to enrich you mocha with 1 to 2 teaspoons of ghee or grass-fed butter.

  • Ice Cubes.

You can also have your coffee frappe topped off with whipped cream. I prefer my drinks vegan, so I decorated my cool beverage with coconut whipped cream instead of heavy cream.
