Prepare really strong coffee (around 4 tablespoons for one cup)
Step 2:
Let it cool then pour into an ice cube tray
Step 3:
When you want to prepare the drink, just throw some cubes in a blender (3-4), add milk(I use around 250 ml of full fat milk), and a drizzle of vanilla coffee syrup, give it a blend until the coffee is combined with the milk then pour into a glass and enjoy!
