Heat the almond milk in a saucepan over high heat. Once it comes to a boil, remove it from the heat and mix in the coffee grounds.
Let the coffee steep for 4 minutes, then strain out the grounds with a fine sieve or a French press.
Place the coffee milk in the fridge for a few hours (ideally overnight) before using.
Make sure the coffee milk is cold before blending with the vegan vanilla ice cream (recipe here). This is also yummy with a brownie or favorite vegan candy bar mixed in.
