The Star of the Show: Coffee Cubes

If you’ve never made iced coffee cubes before, your life is about to change forever. What’s so great about iced coffee cubes? They:

  • Deliver coffee to your iced coffee (of course).
  • Make your iced coffee COLD.
  • Keep your iced coffee from being diluted by traditional ice cubes.
  • Are fun to make!

How to Make Coffee Cubes

Obviously, making coffee cubes entails pouring coffee into an ice cube tray. But there are a few rules to follow:

  • Add COOLED coffee; do not pour steaming hot coffee into ice cube trays. Even if your trays don’t melt, who knows if the plastic will leach into your coffee. Better safe than sorry!
  • 12 oz coffee will fit perfectly in a standard ice cube tray, making each cube approximately .75 oz coffee.
  • That said, it doesn’t matter what size ice cube tray you use. Just know approximately how much coffee you’ve poured into the tray so you know how many ice cubes to use. (I confess I used a non-standard tray for these photos so I could make pretty square ice cubes!)
  • You can make your coffee cubes sweetened or unsweetened. It’s up to you if you want to add keto-friendly sweetener to your coffee cubes or to your actual iced coffee drink. You’ll actually want to over-sweeten a bit because whatever you sweeten will be diluted slightly in the final drink.

How to Make The Best Keto Iced Coffee

Once you’ve made your coffee cubes, add your desired number of cubes to a glass.

Then, pour over nut milk of choice (almond or coconut milk from a carton are your best choices) and heavy whipping cream. If needed, add keto-friendly sweetener to taste. Give your iced coffee a good stir or shake (if your glass has a lid!) and you’re good to go!

How to Enjoy Your Keto Iced Coffee

When you first mix your keto iced coffee, it will be a lot of milk and not much coffee. Don’t start to gulp it down right away; give the coffee cubes time to melt! This iced coffee recipe is best savored over time. Feel free to stir or shake it a few more times as you drink it.

  • I have a question concerning the sweetener. I’ve used sweet n low for years and am having a hard time getting accustomed to the taste of other sweeteners . How long do you think it will take for my pallet to Change? Did you have an issue with this?

    • Hi Carla! Great question. I had been off artificial sweeteners like Sweet n Low for many years prior to keto, so I had an easier transition. What other sweeteners are you trying to use? Some taste better than others. Swerve Confectioners is always my #1 recommendation followed by Lakanto Powdered Monkfruit. You could try mixing them together for a while until your tastebuds adjust and you can transition to purely natural sweeteners.
