There’s nothing tastier on a warm morning than an iced coffee or iced latte, but regular ice cubes can water down your drink, leaving you with a weak-flavored beverage that has lost all its taste. Save your iced latte with Espresso Milk Cubes! These flavor-packed cubes will ADD flavor to your drink, and they’re so easy to make!

I love lattes and other coffees, but I turn my favorite drinks into iced creations when the weather gets hot. This simple hack for making flavored cubes is genius! I add a few to my latte, and as they melt, they add even more flavor to the drink instead of watering it down.

These are so easy to make, too. I love using ice cube trays with lids on them so that they stack up and save room in the freezer. I can make a whole batch of these, then keep them in a zipper-top bag and just grab what I need as I need them.

I use oat milk in this recipe because I love the creamy, nutty flavor it gives to the coffee. But you can use any kind of milk or even cream; use whatever you like! You can also experiment with flavors – see all my suggestions below to transform your iced drink into a barista-worthy creation!

Why I love this recipe

  • It’s so easy to make – you just need some room in your freezer!
  • They make a great drink, transforming an espresso shot into a delicious latte.
  • You can use the cubes in any iced coffee drink; mix and match them to change up the flavors and strength.

How to make the best Espresso Milk Cubes

This will make enough cubes for about two 16-ounce lattes. If you want to make more, it’s easy to double or even triple the cubes. Just make sure you have enough ice cube trays and freezer room to freeze them!

  1. Pull 4 shots of espresso and carefully pour it into an ice cube tray, cleaning up the sides of the tray if needed.
  2. Add the oat milk to another ice cube tray and freeze both trays for 4-6 hours or overnight.
  3. Divide the cubes into two 16-ounce cups or glasses and add a freshly pulled shot of espresso over the cubes and add any extra filled oat milk over the top.
  4. Enjoy!

Tips & substitutions

  • You don’t have to make lattes with these cubes. In fact, you can pop them into any iced coffee drink for a special treat! 
  • Just want 1 latte? Only use half the cubes. 
  • Want a stronger latte? Use more espresso cubes and fewer milk cubes.
  • Freeze the cubes overnight for the best results.
  • Use any ice cube tray, but with lids are great for stacking in the freezer, I bought these trays on amazon and they’re perfect for espresso and milk cubes.

Flavor variations

  • Add a splash of vanilla to the milk before freezing for a subtle vanilla flavor in your drink.
  • Mix a teaspoon of chai powder into the milk before freezing for a chai latte.
  • Love pumpkin spice? Mix ½ teaspoon of pumpkin spice and a pinch of cinnamon into the milk before freezing the cubes for a pumpkin spice latte.
  • Add a splash of your favorite flavored syrup to the oat milk to change up the flavor however you like.

Serving suggestions

I love these Espresso Milk Cubes in an iced coffee drink, and I’ll often make one in my travel mug so I can sip on the go. On days like that, I take along a Banana Muffin or a Blueberry Scone for a light snack. I’ll also make these lattes to enjoy with a picnic lunch which might include some of my favorite recipes like this mayo-less slaw, Jalapeno Cheddar Biscuits, and crustless quiche.

Keep unused frozen cubes in a zipper-top bag in the freezer, or leave them in the ice cube tray. They’ll keep 2-3 months like this.
