Equipment and measurements

Espresso machine, scale, spoon, heatproof cup and milk pitcher or small saucepan.

Amounts marked as brewed espresso describe beverage weight, not dry grounds. Keep water, milk, ice and other additions as separate measurements; final volume varies with the method.

How to make it

Combine 5 g unsweetened cocoa and 8 g sugar in the cup. This recipe uses pure cocoa, not an equal weight of sweet chocolate sauce.
Technique note
Sift obvious cocoa clumps first. Stirring cocoa and sugar together dry helps distribution; sprinkling powder onto a full cup of milk can trap dry centres.
Prepare roughly 36 g espresso. Add a little to the cocoa to form a smooth paste, then gradually stir in the rest, checking the cup bottom for dry pockets.
Technique note
Use the already measured espresso to loosen the paste. An unrecorded splash of water changes the recipe and can mask a mixing problem.
Warm 150 g milk gently, starting around a 55–60°C target. Use a suitable steam wand or saucepan and stir saucepan milk to avoid scorching; do not aim to boil it.
Technique note
Cocoa already adds texture, so a thick cap of dry foam is unnecessary. Excess foam can make it harder to mix chocolate from the base of the cup.
Loosen the cocoa-coffee mixture with a little milk before adding the remainder. Mix thoroughly and taste before adding further sugar.
Technique note
Sweetness changes perceived bitterness but cannot dissolve a powder lump. Fix the texture first, then choose the sweetness.

What to adjust first

Powder at the base: make a paste with a small amount of liquid next time. Sweet but little coffee character: change sugar or milk separately. Burnt flavour: taste the espresso and warmed milk independently.

Keep sauce and cocoa as different ingredients

A chocolate sauce brings its own sugar and water. When switching, begin with a small amount and omit additional sugar initially; do not equate 5 g cocoa with 5 g sauce. Use the product label and taste to guide a separate recipe.

Try this comparison next time

Divide the cocoa-espresso mixture and compare two milk quantities. Decide whether coffee or chocolate should lead, then adjust sugar in another comparison.

What to write down

Record whether cocoa is unsweetened, sugar weight and milk amount. This recipe contains milk and cocoa; whipped cream is optional decoration, not a requirement for a successful cup.
