This oatmeal cookie cold brew is a quick and easy iced coffee that tastes like a cookie in a glass. Made with oat milk, cinnamon, vanilla, and brown sugar, it’s a cozy, refreshing treat perfect for warm days.
For a stronger cookie flavor, let the oat milk and cinnamon mixture sit for 5 minutes before adding the coffee. If using homemade cold brew, ensure it’s smooth and low-acid. Adjust sweetness to taste. The oat milk mixture can be made ahead and stored in the fridge for up to 3 days.
