Let me tell you about my favorite keto coffee drink. I used to spend a lot of money on fancy iced coffees at coffee shops. But when I started keto, I couldn’t have them anymore because they had too much sugar. I really missed my cold, creamy coffee treats.
So I came up with this recipe in my kitchen. It’s just like those expensive coffee shop drinks, but without all the sugar. It’s creamy, cold and perfectly sweet. Best of all, it only takes 7 minutes to make.
I make this keto iced coffee frappe almost every afternoon, and it always hits the spot. When I serve it to friends, they can’t believe it’s sugar-free.
The great thing about this recipe is that you can make it exactly how you like it. Want it sweeter? Add more sweetener. Need more coffee kick? Add stronger coffee. It’s that simple.
I promise you won’t miss those expensive coffee shop drinks once you try this. It’s cheaper, healthier, and tastes just as good. Plus, you don’t even have to leave your house.

Ingredients

Base Recipe
- 1 cup cold brew coffee (or strong-brewed coffee, chilled)
- ½ cup unsweetened almond milk
- 2 tablespoons heavy cream
- 1 cup ice cubes
- 1-2 teaspoons erythritol or monk fruit sweetener
- ½ teaspoon vanilla extract
Optional Toppings
- Sugar-free whipped cream
- Unsweetened cocoa powder
- Sugar-free chocolate syrup
- Cinnamon sprinkle
- Sugar-free caramel drizzle
How To Make
First, start with your coffee. If you’re using regular coffee instead of cold brew, make it stronger than usual and let it cool completely in the fridge for at least 2 hours. You can make this ahead of time the night before.

Once your coffee is cold, get your blender ready. Pour in 1 cup of the cold coffee, ½ cup unsweetened almond milk, and 2 tablespoons of heavy cream.

Add 1 teaspoon of your sweetener to start with. You can always add more later if you want it sweeter. Put in ½ teaspoon of vanilla extract too.

Now add 1 cup of ice cubes to your blender. If you want your drink thicker, you can add a few more ice cubes.

Cover your blender and start blending on low speed for about 10 seconds. This helps break up the ice cubes a bit. Turn the speed up to high and blend for another 20-30 seconds until everything is smooth and frothy. You’ll know it’s ready when you don’t hear any more ice chunks.

Take a small taste. If you want it sweeter, add another teaspoon of sweetener and blend for 5 more seconds.
Pour your frappe into a tall glass. Don’t worry if it looks a bit foamy – that’s exactly what you want. If you like toppings, add some sugar-free whipped cream on top. You can sprinkle a little cocoa powder or add a drizzle of sugar-free chocolate syrup if you want.
Serve right away with a straw. The frappe tastes best when it’s fresh and icy cold.
Quick Tip: If your frappe sits for a while and starts to separate, just give it a quick stir with your straw and it’ll be good as new.
