Keto Coffee Smoothie – The Best Keto Iced Coffee
This keto coffee smoothie is a healthy summer grab’n go breakfast for coffee lovers with only 3.9 grams of net carbs per serving.
If you love milkshakes or frappuccinos, this coffee smoothie is what you need.
What’s A Keto Coffee Smoothie?
Coffee lovers, this recipe has your name on it! If you can’t start the day without your brewed coffee or coffee latte, then you will love this keto coffee smoothie.
Perfect for summer hot days, this keto smoothie with brewed coffee is an amazing swap to your traditional bulletproof latte coffee.
Personally, I love to combine this coffee smoothie with one of my no-bake keto granola bars for a satisfying breakfast on the go.
How To Make A Coffee Smoothie
A coffee smoothie, also known as an iced coffee smoothie, is a delicious cold breakfast drink for coffee lovers.
It is using brewed coffee or instant coffee as the main ingredient.
It also combines other ingredients, including ice cubes or frozen ingredients that add the frothy texture.
While most coffee smoothies use bananas, keto coffee smoothies are sugar-free, dairy-free, and banana-free.
- Choose your favorite coffee – brewed coffee or instant coffee rehydrated in water.
- Cool the coffee down
- Add all the smoothie ingredients to a blender
- Blend on high speed until frothy and smooth
Can I Add Coffee To my smoothie?
Yes, you can add cold-brewed coffee or cold instant coffee to a smoothie.
Of course, you must combine your cold coffee with other ingredients that marry well with coffee, or the flavor can be off.
Keto Coffee Smoothie Ingredients
This keto coffee smoothie is a smooth, refreshing coffee shake perfect summer keto drink to replace your regular bulletproof latte coffee.
Therefore, it is using almost the same ingredients, including:
- Chilled brewed coffee – make sure you cool the coffee before adding it to the blender. You can make ahead some brewed coffee, store it in the fridge, and use it the next morning. Another great way to make a coffee shake is to freeze coffee into ice cube trays. Use the coffee ice cubes in the recipe, and don’t add the suggested ice cubes!
- Unsweetened almond milk or unsweetened coconut milk if you love coconut flavor in your coffee shake.
- Ice cubes – this adds a frothy texture to your coffee.
- Almond butter – Like bulletproof coffees, keto coffee smoothies use fat to create a creamy texture. Butter doesn’t blend well in cold drinks. That’s why nut butter like peanut butter or almond butter is the best for keto breakfast smoothie recipes.
- Erythritol or any sugar-free keto-friendly sweeter you like including allulose or xylitol. If you are adding protein powder as suggested in the next step, decreasing erythritol to just 1 tablespoon of the coffee shake would be too sweet!
- Keto vanilla collagen protein powder – this is optional, but it boosts the texture, protein, and fat of your smoothie. I love to use vanilla collagen powder in my keto smoothie. But watch out. Some brands sweeten their collagen powder, so you will have to decrease the erythritol to avoid an overly sweet low-carb smoothie.
- Vanilla extract or vanilla-flavored stevia drops – add 1/4 teaspoon for a boost of vanilla.
Add-on Ideas
You can tweak coffee smoothies in so many ways! Below I listed my favorite keto add-ons to make this low-carb coffee smoothie even more delicious:
- Ripe avocado – adds some healthy fat and fudgy texture to your drink by adding up to 1/2 ripe avocado flesh.
- Sugar-free vanilla syrup or caramel syrup – replace the erythritol with a tablespoon of sugar-free flavored syrup.
- Dairy-free yogurt – a dollop of coconut yogurt add a delicious, creamy, smooth texture and lovely coconut flavor.
- Sugar-free chocolate chips – adding 1 tablespoon will remind you of your favorite coffee chocolate chips Frappuccino of a popular coffee.
- Unsweetened whipped cream – swirl some whipped cream on top of your coffee to bring dessert for breakfast.
- Unsweetened cocoa powder – for a light chocolate flavor, trust me, you want this!
- MCT oil – to boost fat and fat burning
Frequently Asked Questions
Can I Use Instant Coffee?
Yes, you can use instant coffee in this recipe. First, dissolve 2 teaspoons of instant coffee into 8 oz of hot water.
Then, cool down the coffee, even store it in the fridge for best results. Finally, use the recipe as a replacement for brewed coffee.
Can I Use Ground Coffee In Smoothies?
It is safe to eat ground coffee in a very small amount.
Therefore, it can be used to flavor a chocolate smoothie, but you can’t use ground coffee to make this keto coffee smoothie.
This recipe needs 8 oz of brewed coffee or the same volume of coffee made with instant coffee granules.
How Does A Coffee Smoothie Taste?
This low-carb smoothie tastes like a coffee milkshake or coffee frappuccino with a touch of cocoa and vanilla if you are using vanilla collagen powder too.

Loved this! Tried with peanut butter but going to try almond butter next time to switch it up. I did not have heavy cream and don’t do dairy, so used 1/3 cup of almond milk instead. Worked well for me!
Delicious! I’m not a coffee drinker, though I do love a frappuccino or a latte. This hit the spot, because I love the fact that coffee is a stimulant. It’s like bulletproof coffee kicked up a notch. Thank you for sharing your talent and your recipes.
Thanks for the lovely feedback
I made this one and I have to thank you, Carine, and the others who are talented enough to put together these recipes. For mine, I used my traditional Trung Nguyen Vietnamese grown French Roast in a regular coffee maker (wonder what it’d be like in a French press?), let 8 ounces cool in the refrigerator overnight, and took it from there. I used the ‘scoop’ that came with my collagen, which did appear to be approximately a tablespoon. It was NOT vanilla flavored. I’m working my way up on the MCT oil after reading about some of it’s potential ‘effects’ – 1 teaspoon yesterday, 2 today. Since I normally drink my coffee straight, I immediately started the erythritol at 2.5 tablespoons and then today knocked it down to 2 tablespoons, and went with your 1 tablespoon of unsweetened cocoa add in. It was AWESOME both times and I could drink it every day. My wife isn’t a coffee drinker but she tried it and liked it also. I’ll try some of your other add in suggestions later on, but for the time being, I’m very content with this combination. I will say that I cannot help but wonder how this would taste using peanut butter and unsweetened cocoa, and do you recommend then NOT using any MCT oil? Thanks again!
This is delicious and my daughter loves having it in the morning especially as she is running out the door for school! I have two quick questions. Do you think we could use coconut milk powder in place of coconut cream? I’m trying to make her a quick mix that she can dump, blend, and go with. Also, if we were to add cocoa powder for more of a mocha, do you think 1 tbs would be a good starting point? Thank you. We love your recipes!
I am glad she love it! Feel free to experiment with powder, I didn’t try that before so I can’t recommend on quantities I am sorry. Enjoy
