In a large bowl, mix all ingredients together until well combined. Let sit for 5 minutes then stir again.
Cover and refrigerate for at least 4 hours. Divide the mixture between two glass jars.
Enjoy as is or add your favorite toppings such as Greek yogurt, granola, cacao nibs, shredded coconut, berries, or banana slices.
Notes
*I use Stok cold brew, which is available in the refrigerated section of your grocery store. You could also use a strongly brewed hot coffee that has cooled off, or even instant coffee.Store in an airtight container in the fridge for up to 4-5 days. For more variations and substitutions, see full blog post above.
