Keto Pistachio Iced Coffee

You know that feeling when you just want a fancy coffee shop treat without blowing your carbs or spending $7?

That’s where this Keto Pistachio Iced Coffee comes in.

It’s creamy, nutty, lightly sweetened, and absolutely delicious.

Bonus: it’s super easy to make and feels like a little hug in a cup!

My kids think it smells amazing (even though they don’t drink coffee yet), and it’s my go-to pick-me-up when I need something indulgent but guilt-free.

Let’s do this!

What You’ll Need

For the Coffee:

  • 1 cup brewed coffee (cooled)
  • 1/2 cup unsweetened almond milk
  • 2 tbsp heavy cream
  • 2 tbsp sugar-free pistachio syrup
  • 1 tsp powdered erythritol (optional, for extra sweetness)

For the Topping:

  • 1 tbsp crushed pistachios (optional but so worth it!)
  • Ice cubes
What You’ll Need

Pro Tips

  1. Chill the coffee first: Brew your coffee ahead of time and pop it in the fridge. Hot coffee will melt the ice too fast.
  2. Customize the sweetness: Taste as you go! Everyone’s sweetness preference is different.
  3. Blend it if you’re fancy: If you want a frappé vibe, blend it all up with ice instead of pouring it over ice.
  4. Pistachios for the win: Crushed pistachios on top aren’t just pretty—they add a little crunch that’s next-level.
  5. Use good coffee: It’s the base of the drink, so pick a coffee you love!

Tools Needed

  • Coffee maker (or French press)
  • Tall glass
  • Spoon for stirring
  • Measuring spoons

Substitutions and Variations

  • No almond milk? Use coconut milk or any other low-carb milk alternative.
  • Out of pistachio syrup? Try sugar-free vanilla syrup for a similar vibe.
  • Want it dairy-free? Swap the heavy cream for coconut cream.
  • No erythritol? Stevia drops work great!

Make Ahead Tips

  • Brew a big batch of coffee and store it in the fridge for quick drinks all week.
  • Crushed pistachios can be pre-chopped and kept in an airtight container.
