This recipe uses your leftover morning coffee. You prevent waste, and your coffee is already cooled and waiting for you when you’re ready for coffee round number two.

Hazelnut Iced Coffee Ingredients
- 1 cup cooled coffee (left over from the morning works great)
- ¼ cup milk
- 1 tablespoon hazelnut syrup
- Ice
Instructions
- Take your cooled coffee from the fridge and pour it over a cup of ice in a tall glass.
- Add the hazelnut syrup and milk, and give it a good stir.
- Sip and enjoy!

This yummy iced coffee is also a nice afternoon treat alongside a couple of these 3 ingredient peanut butter cookies.
Ingredient Notes and Substitutions
- Coffee: Leftover morning coffee works great. Just make sure it’s cooled before it goes over the ice.
- Milk: I use whole milk in my iced coffees, but oat milk or another non-dairy milk works too. You can also use half & half, or skip the milk and keep it black.
- Syrup: This version is hazelnut, but you can make it any flavor you love or have on hand. Just swap out the syrup and you have a whole new drink.

Storage
If you make extra coffee in the morning, pour the leftovers into a mason jar and keep it in the fridge. That way, cooled coffee is ready whenever you want an afternoon iced coffee.
