Cinnamon Oat Milk Foam Cold Brew

Millie Pham

If you love a fancy coffee shop cold brew but don’t love the price tag, this homemade cinnamon oat milk foam cold brew is about to be your new best friend. It’s creamy, just the right amount of sweet, and has that perfect cinnamon flavor that makes every sip feel like a treat. Best part? It’s super easy to make at home, and you don’t need any fancy equipment—just a milk frother or blender!

What You’ll Need

Cold Brew & Sweetener:

  • 1 cup cold brew coffee
  • 1 teaspoon maple syrup (or sweetener of choice)
  • Ice cubes

Cinnamon Oat Milk Foam:

  • ½ cup oat milk (barista-style works best!)
  • 1 teaspoon maple syrup
  • ¼ teaspoon ground cinnamon
  • ¼ teaspoon vanilla extract

Pro Tips

✅ Use barista-style oat milk—it froths much better than regular oat milk.
✅ Adjust sweetness to your liking! Add more or less maple syrup depending on how sweet you like your coffee.
✅ A handheld milk frother works best for the foam, but a blender or even a jar with a tight lid (for shaking) can do the trick!
✅ Want extra cinnamon flavor? Add a tiny pinch of cinnamon directly into the cold brew before stirring.
✅ Serve immediately! The foam will slowly mix in with the coffee, so enjoy it fresh for the best texture.

Tools You’ll Need

✔️ Milk frother (or blender/jar with a lid)
✔️ Measuring spoons
✔️ Tall glass
✔️ Spoon for stirring

Substitutions & Variations

🌿 Dairy-Free? Oat milk is already dairy-free, but you can swap it for almond milk, coconut milk, or soy milk!
🍯 Sweetener Swap? Use honey, agave syrup, or simple syrup instead of maple syrup.
No Cold Brew? Brew strong coffee, let it cool, and use that instead.
🧊 Extra Fancy? Sprinkle a little extra cinnamon on top of the foam before serving!

How to Make Cinnamon Oat Milk Foam Cold Brew

1. Fill Your Glass with Ice and Cold Brew

Pour 1 cup of cold brew coffee over ice in a tall glass. Stir in 1 teaspoon of maple syrup for sweetness.

2. Make the Cinnamon Oat Milk Foam

In a small cup or frother, combine ½ cup oat milk, 1 teaspoon maple syrup, ¼ teaspoon ground cinnamon, and ¼ teaspoon vanilla extract. Froth until light and airy.

3. Pour the Foam Over the Cold Brew

Gently pour the cinnamon oat milk foam over the iced cold brew, letting it float on top.

4. Enjoy!

Give it a gentle stir if you like, or sip it as is for that perfect layered effect.

Leftovers & Storage

☕ Best enjoyed fresh! The foam will deflate over time.
❄️ If you need to prep ahead, you can store the frothed oat milk separately in the fridge for a few hours, then re-froth before serving.
