Pour 3 cups of cold water into a glass quart-sized jar or other container.
Add your favorite ground coffee and the espresso powder.
Stir to combine, making sure all the coffee grounds become wet.
Cover the jar or container and allow the coffee to steep in the refrigerator for 12-24 hours. The longer you allow it to steep, the stronger the flavor will be.
After the coffee has steeped, line a mesh strainer with a coffee filter or cheesecloth and set the strainer on top of a pitcher or another glass jar.
Pour the brewed coffee into the mesh strainer to remove the grounds.
Fill a large glass with ice and pour 3/4 full with the cold brewed coffee. Top with a heavy pour of cream (coconut or almond milk are great if you're dairy-free), and 2 pumps of liquid sweetener.
Stir and enjoy!
The cold brewed coffee will keep about a week if stored in airtight container in the refrigerator.
This recipe makes enough cold brewed coffee to serve 3-4 iced coffees. It can easily be doubled (or tripled!), if needed. Just be sure to use it within a week-10 days.
