Keto Pumpkin Spice Frappuccino: Best Recipe

It’s unfortunate when your favorite food or beverage doesn’t fit your current diet plan.

If you’re on a low-carb diet, and you’re a fan of this flavorful and refreshing Starbucks drink, you’ll most likely love my Keto Pumpkin Spice Frappuccino recipe.

It’s quite easy to make such a coffee frappe at home. The most tricky part is actually choosing the components you’re going to use for the DIY Frappuccino.

So I made sure to include proper keto-friendly ingredient recommendations that will let you enjoy the best possible pumpkin spice bulletproof coffee.

The Homemade Keto Pumpkin Spice Frappuccino contains 3 net carbs per serving.

And that’s in case you use all of the ingredients I listed.

If you read through the ingredient section, you’ll find out that you can lower the net carbs to 1 gram per serving and still enjoy your Pumpkin Spice Frappe.

So let’s dive in.

You don’t have to use all of the listed recipe components to make a delicious Keto Pumpkin Spice Frappuccino at home.

I recommend reading through the ingredients and the tips that can be found under each one of them. This way you’ll get to figure out which ones to use according to your personal taste and according to the products you have available at home.

So here are the recipe ingredients for a Keto Pumpkin Spice Frappuccino:

  • Pumpkin puree – 1 tbsp (0.5 oz or 15 grams).

    The pumpkin puree will add flavor and richness to your keto-friendly pumpkin spice frappe and will take it to the next level.

    A serving (1/2 cup, 4 oz. or 120 grams) of pumpkin puree contains 8 grams of net carbs. Therefore a tablespoon of pumpkin puree, which is usually around 0.5 oz. or 15 grams would only contain 1 net carb.

    If you don’t have a jar of homemade pumpkin puree at home, you can get a canned version, such as this one by Farmer’s market (Amazon link).

    Of course, you can skip this recipe component to reduce the homemade Frappuccino’s contribution to your daily carb intake. Even without it, you will still get to enjoy your DIY pumpkin spice coffee, especially if it contains the next ingredient.

  • Pumpkin Pie Spice – 1 teaspoon.

    This is the most essential recipe component when making your low-carb Pumpkin Spice Frappe. A teaspoon of pumpkin pie spice contains an insignificant amount of carbohydrates, so you won’t have to worry about its impact on your keto diet plan.

    The Pumpkin Pie Spice adds the signature flavor of this fall coffee beverage that we all know and love.

    You can make it at home by mixing cinnamon, cloves, ginger, allspice, and nutmeg.
  • Almond Milk: 4 fl oz (120 ml).

    Almond milk is a staple ingredient in many keto-friendly recipes. After all, the unsweetened version contains up to 1 gram of carbs per serving (1 cup, 8 oz., 240 ml).

    I only add 4 fl. oz. (120 ml.), but if you feel like you want to add more, that’s totally fine. I prefer using less almond milk (sometimes even 2 to 3 ounces) for my Keto Pumpkin Spice Frappuccino, as I enjoy a better-pronounced coffee flavor.

    If I add a full 8 oz (240 ml) cup of almond milk, the coffee flavor gets too diluted for my liking.
  • Full Fat Canned Coconut Milk – 2 tablespoons (1 oz, 30 grams).

    I like adding 2 tablespoons of full-fat canned coconut milk to my frappe mixture before blending, as it makes the drink creamier and very satisfying.

    My boyfriend likes whipping the thick coconut milk with a bit of erythritol and adding it as a topping to his keto pumpkin spice beverage.

    It’s up to you how (or whether) you’re going to use it when making yours.

    What’s worth noting is that 1 oz. (30 grams) of full-fat canned coconut milk contains around 1 gram of net carbs. So it’s a great keto-friendly recipe addition that will improve your frappe’s creaminess and overall flavor.
  • Xanthan Gum – 1/4 teaspoon (optional, as a thickening agent).

    If you don’t want to add thick coconut milk to your keto Frappuccino, but you still want a more viscous frozen drink add 1/4 of a teaspoon of xanthan gum. Virtually all Starbucks Frappuccinos contain this thickening agent.

  • Espresso shot/ 4 ounces of brewed coffee.

    I like adding a double espresso shot to my bulletproof pumpkin spice frappe.

    If you don’t have an espresso machine, feel free to use the coffee brewing device you have at hand (French press, Aeropress, moka pot, Keurig, Nespresso machine, drip coffee maker, etc).

    When making non-keto copycat Starbucks Frappuccinos I do often use instant coffee.

    Starbucks baristas use something called Frappuccino roast for such frozen coffee drinks, which is basically instant coffee powder dissolved in room-temperature water. Nevertheless, unlike brewed coffee, instant coffee may contain carbohydrates (around 0.8 grams per teaspoon) Espresso may also contain a negligible amount of carbs – around 0.5 grams.

    That’s not that big of a deal, but it’s worth taking into consideration when making a keto drink at home.
  • MCT oil: 1 teaspoon.

    Of course, you don’t have to add MCT oil to your keto-friendly pumpkin spice frappe. It will still be a low-carb keto-approved drink even without this ingredient.

    Nevertheless, I like adding a teaspoon of MCT oil if I have it in the morning or in the late afternoon when I need a satiating bulletproof coffee Frappuccino.

    When adding this component, I feel more energized and productive for longer.
  • Liquid Stevia/Erythritol (or both).

    Both liquid stevia and erythritol are keto-approved low-carb sweeteners that will improve your pumpkin spice frappe’s overall taste.

    Still, their flavors take some getting used to.

    I’ve found that adding both erythritol (a teaspoon) and liquid stevia (3 to 4 drops) results in the best-tasting coffee drink. It seems like these sweeteners complement each other in a way that results in a flavor closer to what we’re used to when not on a keto or a low-carb diet.

    Using a sugar-free syrup to sweeten your DIY pumpkin spice Frappuccino is also an option.

  • Vanilla Extract.

    If you have a vanilla extract available, add a couple of drops to the mixture before blending. Its flavor goes very well with this keto frappe.
  • Ice cubes – 1 cup.

How to make a Keto Pumpkin Spice Frappuccino: Recipe Directions

To make a Keto Pumpkin Spice Frappuccino do the following:

  1. Pour all of the ingredients in a blender.
  2. Blend until smooth and pour in a glass.

As I mentioned I prefer adding the full-fat canned coconut milk to the mixture itself, not as a topping.

To finish off my Keto Pumpkin Spice Frappe I sprinkle it with a bit of pumpkin pie spice instead.

This is a perfect low-carb drink for vegans too, as all of its ingredients are plant-based.

So if you’re a vegan and want to have a healthy and flavorful bulletproof Frappuccino at home, try out this recipe.

The keto-friendly pumpkin spice frappe will let you enjoy a delicious Starbucks drink at home, without kicking you out of ketosis.
