“Bulletproof” Keto Iced Coffee

In the summer, it doesn’t get much more refreshing than an iced coffee from your favorite coffee shop. However, most of those delicious coffee drinks are packed with sugar and carbohydrates.

This iced bulletproof coffee is cold and creamy, with an extra boost of good fats to keep you in ketosis! It’s easy to whip up in your blender in just a couple minutes, which is less time than it takes to head over to the drive through! Consider it a keto Starbucks copycat…that’s so good you won’t miss the “real” thing!

Keto Iced Coffee and all the ingredients needed to make it

What is Bulletproof Coffee?

When I first started keto and discovered bulletproof coffee, it was a moment! I couldn’t believe how rich and creamy the coffee tasted, and what an awesome froth you could get when you made it!

What makes bulletproof coffee different than normal coffee is the addition of butter or MCT oil (or both). This provides healthy fats, which are the body’s fuel on a keto diet. The richness of the drink also helps keep you feeling full and prevents some of the caffeine jitters that you might get from drinking plain coffee on an empty stomach.

“Bulletproof coffee” is a trademarked name kind of like “Kleenex” is to tissues. So this recipe is a keto iced coffee, made in the bulletproof coffee style.

Cold coffee has a way of always hitting the spot, and this Iced Keto Coffee is the perfect go-to! With this simple recipe, you can make your favorite iced coffee keto approved!

Prep Tips

  • Try adding your favorite sugar-free syrup to customize your coffee drinks! Sugar-free vanilla syrup, caramel sauce, hazelnut, or mocha are all flavors that would pair well in this low carb iced coffee.
  • Blend a scoop of collagen powder into your bulletproof coffee for an extra boost. My mom swears by her daily collagen coffee and her skin looks amazing as proof!
  • Top your drink with sugar free whipping cream for an extra special treat!

Frequently Asked Questions

Is Regular Dairy or Almond Milk Better for Keto?

This recipe can be made with either regular dairy or plant-based milks, depending on your preference. There are pros and cons to both, so here is a quick breakdown of our milk recommendations:

  • If you prefer the taste of real dairy, I suggest using heavy cream for this recipe. Skim milk and low fat milk often have a higher sugar and carb count, so they are generally avoided on a ketogenic diet.
  • My favorite keto-friendly dairy-free milk is almond milk because it is lower in carbs than real dairy. When made with almond milk, one serving of this keto iced coffee contains just 1g total carbs and 0g net carbs. Can’t beat that! Just make sure to use unsweetened almond milk. I like to use sugar-free vanilla almond milk because it gives an extra boost of sweetness that makes a truly decadent tasting drink! Unsweetened coconut milk or cashew milk are other great options. And while I love oat milk, it is not keto-friendly.

Can You Keep Bulletproof Iced Coffee in the Fridge?

Technically yes, you can keep this iced coffee in the fridge. However, chilling the drink like this can cause the butter to harden and may affect the texture of the drink.

If you’d like to make a big batch and keep it in the fridge for later, I recommend using coconut or MCT oil instead of butter. That way there will be no issues with chilling or refrigerating the drink.

Can You Use Cold Brew Coffee in this Recipe?

Cold brew in an iced coffee? Sounds like it makes sense!

The only problem is that cold coffee won’t melt your butter. BUT you can swap out the butter with MCT oil, which will blend in the cold brew coffee.

Can You Use Coffee Creamers?

There are some keto creamers on the market, and you’re welcome to add them to this recipe. One thing I do want to mention is that for myself, I notice that weight loss slows down when I add processed foods. So even though a creamer might be sugar free or low carb, you might want to limit those types of foods until you are sure you’re in ketosis and that they don’t affect your progress.
