Hot Chocolate Tiramisu: Coffee-Infused Mug Dessert
Many cooks pour boiling liquid directly into egg yolks when making hot chocolate tiramisu. This mistake causes the eggs to curdle, producing a grainy, split texture instead of a smooth cream. You must control the temperature to ensure the proteins do not clump.
This dessert is a warm, liquid version of the classic Italian treat. It consists of a silky chocolate and coffee base topped with a light, airy blend of mascarpone and whipped cream. When correct, the result is a glossy, homogenous glaze and a stable, cloud-like topping.
The critical step is tempering the eggs. You must pour a small amount of hot chocolate into the yolk mixture while whisking constantly. This stabilises the yolks before you incorporate the rest of the liquid, which prevents curdling and ensures the final texture remains silky.

Recipe cardIngredients
Instructions
-
Heat the base
Combine the milk, 200 ml of double cream, vanilla extract and 10 g of caster sugar in a saucepan. Heat over medium-low until the sugar dissolves. Do not let the mixture boil or you risk scorching the milk.
-
Infuse the chocolate
Whisk in the cocoa powder until the liquid is smooth. Keep the mixture at a gentle simmer. Add the instant coffee granules and stir constantly for 1 to 2 minutes to keep the chocolate silky.
-
Strain the liquid
Pass the hot chocolate through a fine-mesh sieve into a jug or pre-heated mugs. This removes any undissolved lumps of cocoa. Allow it to cool slightly while remaining steaming hot.
-
Prepare the mascarpone
Whisk the egg yolks, 5 g of caster sugar and the mascarpone in a chilled bowl. Beat the mixture until it is smooth, pale and homogenous. This ensures a stable base for the cream.
-
Temper the eggs
Pour the hot chocolate into the mascarpone mixture while whisking constantly. This gradual introduction prevents the eggs from curdling. Continue whisking for 1 to 2 minutes until the glaze thickens.
-
Lighten the cream
Transfer the thickened glaze to a second bowl and whisk in 50 ml of double cream until glossy. In a separate bowl, beat the remaining double cream and 5 g of caster sugar to soft peaks. Fold the whipped cream into the glaze carefully to keep it airy.
-
Assemble the mugs
Spoon the warm hot chocolate into the mugs. Add a generous spoonful of the mascarpone-cream blend and top with the folded whipped cream. Dust the surface with espresso powder to finish.
Temper the egg yolks slowly to avoid curdling. Pour a small amount of hot chocolate into the yolk mixture while whisking before adding the rest. If the mixture looks grainy, you have added the hot liquid too quickly and the eggs have scrambled.
What goes wrong and why
Egg yolks curdle when they hit high heat too quickly. You will see small, cooked clumps in the cream if this happens. Pour the hot chocolate into the yolks slowly while whisking constantly. This tempering process stabilises the proteins so the mixture stays smooth and glossy.
What to serve with it
Serve these mugs with a buttered biscotti for a classic pairing. You may also drizzle a thin ribbon of dark-chocolate sauce over the top or sprinkle toasted coconut flakes over the whipped cream for a tropical twist. These additions provide contrasting textures to the silky cream.
Storing and reheating
Do not refrigerate the assembled dessert as the whipped topping will lose volume. Store leftover hot chocolate in the fridge for up to 4 days and reheat it gently. You can freeze the base for up to 2 months, thawing it in the refrigerator overnight before reheating.

Questions people ask
Can I make this without dairy?
Yes. Use unsweetened coconut milk and coconut cream instead of whole milk and double cream. Swap the mascarpone for a plant-based alternative to maintain the same flavour profile while catering to dairy-intolerant diners.
How do I stop the whipped cream from collapsing?
Chill your bowls and beaters before you start. Stop whisking when soft peaks form but remain slightly droopy. Over-whipping the cream ruins the silky texture and makes it unstable when folded into the mixture.
Can I add spices to the chocolate base?
Yes. Add a pinch of cinnamon or 0.5 tsp of ground cardamom to the hot chocolate. These spices add an aromatic depth of flavour that complements the coffee notes and adds warmth to the dessert.
