Why This Recipe Works (Quick Science)
Cold brew coffee is naturally less acidic than regular hot coffee, giving it a smoother taste. Oat milk contains proteins and natural starches that trap tiny air bubbles when frothed. The maple syrup adds sweetness while helping create a slightly thicker foam. Cinnamon dissolves into the foam and spreads its flavor throughout every sip.
Recipe and Instructions
Step 1: Make the Cinnamon Oat Milk Foam
In a small cup or jar, combine 1/2 cup oat milk, 1 teaspoon maple syrup, and 1/4 teaspoon ground cinnamon. Froth for about 30 seconds until the mixture becomes light, creamy, and foamy.
Step 2: Fill the Glass with Ice
Add 1 cup ice cubes to a tall serving glass.
Step 3: Pour in the Cold Brew
Slowly pour 8 ounces cold brew coffee over the ice cubes.
Step 4: Add the Foam
Spoon or gently pour the cinnamon oat milk foam over the cold brew. Let the foam sit on top to create beautiful layers.
Step 5: Garnish and Serve
Sprinkle a small pinch of extra ground cinnamon over the foam and serve immediately.
Common Mistakes
- Using warm oat milk can make the foam thin.
- Overfilling the glass with ice leaves little room for coffee.
- Stirring immediately removes the layered look.
- Using old cinnamon can make the flavor weak.
- Frothing for too little time can create a flat foam.
