If you love iced coffee and cookies, you’re about to meet your new favorite drink—Oatmeal Cookie Cold Brew!
It’s smooth, creamy, and tastes just like a fresh-baked oatmeal cookie in a glass. This is the perfect pick-me-up for busy mornings or an afternoon treat that feels like a little indulgence.
The best part? You can make it at home with simple ingredients, no fancy barista skills required!
Let’s get started!
What You’ll Need
Cold Brew Coffee:
- 2 cups cold brew coffee (store-bought or homemade)
- ½ teaspoon ground cinnamon
- ¼ teaspoon vanilla extract
Oatmeal Cookie Creamer:
- 1 cup milk (whole, oat, or almond)
- 2 tablespoons sweetened condensed milk
- 1 tablespoon maple syrup
- ½ teaspoon cinnamon
- ¼ teaspoon nutmeg
- ¼ teaspoon vanilla extract
Toppings (Optional but Highly Recommended!):
- Crushed oatmeal cookies
- Extra cinnamon for dusting

Pro Tips
✔️ Use fresh cold brew. If making your own, steep coarsely ground coffee in cold water for 12-24 hours for the smoothest flavor.
✔️ Adjust the sweetness. Taste the creamer before adding it to your coffee—add more maple syrup if you like it sweeter.
✔️ For extra cookie flavor, blend a small oatmeal cookie into the creamer for a thicker, cookie-infused drink!
✔️ Shake it up! If you don’t have a frother, shake the creamer in a mason jar for a light, frothy texture.
✔️ Make it dairy-free by using oat milk and skipping the sweetened condensed milk.
Tools You’ll Need
- Large jar or pitcher for cold brew
- Small saucepan
- Whisk
- Measuring spoons and cups
- Mason jar or milk frother
- Tall glass for serving
Substitutions & Variations
✨ No cold brew? Use strong brewed coffee that has been chilled.
✨ Less sugar? Skip the condensed milk and just use maple syrup.

Make-Ahead Tips
✔️ The oatmeal cookie creamer can be made up to 5 days ahead and stored in the fridge.
✔️ Cold brew coffee stays fresh for up to a week, so make a big batch!
