Cold foam is the silky, velvety topping that turns any iced coffee into a café-worthy drink. Made with cold milk whipped without heat — it floats on your cold brew and slowly cascades down as you sip. Make it at home in 60 seconds.
What You'll Need
- 2–4 oz cold nonfat or 2% milk (nonfat froths best)
- Handheld milk frother, blender, or mason jar with lid
- Optional: vanilla syrup, cinnamon, or sea salt
Step 1 — Choose Your Milk
Nonfat milk produces the thickest, most stable cold foam. Whole milk = richer and slightly less thick. Oat milk works great dairy-free. Always use milk ice cold straight from the fridge.
Step 2 — Pour and Flavor
Pour 2–4 oz of cold milk into a tall cup. If adding flavor, stir in ½ tsp vanilla syrup or a pinch of cinnamon before frothing.
Step 3 — Froth Until Thick
Handheld frother: Submerge tip just below the surface, froth 20–30 seconds moving slowly up and down until foam doubles in volume.
Mason jar method: Fill halfway, seal tight, shake hard 30–45 seconds until frothy and thick.
Step 4 — Spoon Over Your Iced Coffee
Build your cold brew or iced coffee first. Spoon cold foam gently on top — it floats and holds its shape. Do not stir — let it slowly melt as you sip.
Step 5 — Finishing Touch
Dust with cinnamon, cocoa powder, or flaky sea salt for a professional finish. Serve immediately.
