Instant coffee, sugar and boiling water whip into a glossy caramel-colored foam stiff enough to sit on cold milk without sinking. The trick is a 1:1:1 ratio, water that's actually boiling, and whipping past the point where you think it's done — you want it to hold peaks like meringue. Spoon it over iced milk for the classic look, or float it on hot milk for something closer to a home-made cappuccino.
Ingredients
Whipped coffee
2 tbsp instant coffee granules or powder
2 tbsp granulated sugar
2 tbsp boiling water
1 pinch fine sea salt
1/4 tsp vanilla extract (optional)
To serve
1 1/2 cups whole milk, or oat milk
2 cups ice cubes (for the iced version)
cocoa powder, cinnamon, or grated dark chocolate for dusting
2 tsp simple syrup or maple syrup, to sweeten the milk (optional)
Instructions
Choose a bowl that looks too big for the job — a medium mixing bowl, ideally metal or glass with a rounded bottom. The foam quadruples in volume, and a narrow bowl keeps the beaters submerged so it whips faster.
Add 2 tablespoons instant coffee, 2 tablespoons granulated sugar and a pinch of salt to the bowl. If your instant coffee is freeze-dried in large shards, crush it between your fingers first so it dissolves cleanly.
Bring a few tablespoons of water to a full boil (or use water just off the boil from a kettle, about 200°F/93°C). Measure exactly 2 tablespoons and pour it over the coffee and sugar. Stir 15 seconds with a spoon until the sugar is dissolved and you have a dark, syrupy slurry with no grit.
Whip with a hand mixer on medium-high for 3 to 5 minutes. It will go from thin and dark, to bubbly and mahogany, to pale caramel and thick. Stop when the beaters leave defined ridges and a lifted beater pulls up a peak that only just curls at the tip. If using vanilla, beat it in for the last 10 seconds.
Test it: drag a spoon through the foam. The channel should stay open for several seconds. If it collapses, keep whipping in 30-second bursts — under-whipped foam sinks straight into the milk.
For the iced version: fill two tall glasses with ice, pour in 3/4 cup cold milk each (sweeten with a teaspoon of syrup first if you like), leaving 1 1/2 inches of headroom. Spoon half the whipped coffee onto each, mounding it high, and smooth the top with the back of the spoon.
For the hot version: warm the milk in a small saucepan over medium heat to about 150°F (65°C), just steaming with no bubbles breaking, about 2 minutes. Divide between two mugs and float the whipped coffee on top.
Dust with a little cocoa powder or cinnamon and serve immediately with a long spoon. Stir it down into the milk before drinking — the foam alone is intensely strong and sweet, and it's meant to be folded in.
Chef's tips
This only works with instant coffee. Ground coffee, espresso powder blends with additives, or brewed coffee will not whip — the freeze-dried coffee solids are what build the foam. Cheap supermarket instant granules actually perform beautifully.
No hand mixer? Use a whisk and a small deep bowl and expect 8 to 10 minutes of hard, fast whisking. A milk frother wand works in about 90 seconds if you keep it moving in a narrow jar. A stand mixer with the whisk attachment struggles with this small a volume unless you double the batch.
Doubling or tripling is easy — just keep the ratio at equal parts coffee, sugar and boiling water. A triple batch whips in the same 4 to 5 minutes.
Cutting the sugar below the 1:1 ratio makes a looser foam that sinks faster. If you want a less sweet drink, keep the full sugar in the foam and leave the milk unsweetened.
Leftover foam keeps in a covered container in the fridge for up to 3 days. It will deflate somewhat; re-whip for 30 seconds before using.
For a mocha version, sift 1 teaspoon unsweetened cocoa powder in with the coffee and sugar, and add an extra teaspoon of boiling water.
