Coffee Zabaglione: Espresso Custard Recipe, Warm and Chilled Versions

Coffee zabaglione is a warm Italian custard made with egg yolks, sugar, and espresso , whisked together over a double boiler until thick, pale, and foamy. Traditional zabaglione uses Marsala wine. This version replaces it with a double shot of dark roast espresso. The result is a light, intensely flavored espresso dessert , ready in under 15 minutes with 5 ingredients.

This guide covers the warm version, the chilled version, and 3 serving ideas.

Coffee Zabaglione Ingredients (serves 4)

How to Make Coffee Zabaglione

Zabaglione requires indirect heat , a metal bowl set over a pot of barely simmering water. Direct heat scrambles the eggs. The bowl should not touch the water. Whisk egg yolks and sugar in the bowl before placing it over the pot. Whisk constantly for 2 minutes until the mixture turns pale yellow. Add the cooled espresso in a slow stream, whisking continuously. Whisk over heat 6 to 8 minutes until the mixture triples in volume, turns pale and foamy. Pull from heat immediately. Serve warm in glasses or coupe dishes. Use Blackout's Brewtal Awakening dark roast for a bold espresso base. See our espresso drinks guide for how to pull a strong double shot at home.

For a chilled version, fold 1/2 cup of lightly whipped heavy cream into the finished warm zabaglione, then refrigerate for 2 hours. The cream stabilizes the foam and produces a thicker, spoonable sauce. Use chilled coffee zabaglione over vanilla ice cream, panna cotta, or pound cake. The espresso flavor intensifies when chilled. Reduce sugar to 2 tablespoons if serving over something sweet.

Idea 1 , Warm over ladyfingers: spoon warm coffee zabaglione over a row of plain ladyfinger biscuits. The custard soaks into the biscuits like a deconstructed tiramisu. Idea 2 , Chilled over ice cream: pour chilled zabaglione over a scoop of vanilla ice cream. The espresso sauce makes a simple ice cream dessert taste complex. Idea 3 , In a shot glass: serve 2 tablespoons warm in an espresso glass alongside a full double shot. The custard and the coffee arrive together at the table.

FAQ: Coffee Zabaglione

Rich, eggy, and intensely coffee-flavored , lighter in texture than a mousse, warmer and fluffier than a custard. The egg yolks add a richness that softens the espresso's bitterness. The sugar level is low enough that the coffee flavor comes through clearly. It tastes like a very light espresso cream , nothing else quite compares.

Yes. Use a metal or heatproof glass bowl set over a pot of barely simmering water. The bowl must not touch the water , the steam does the work. Avoid plastic bowls , they do not conduct heat evenly. A stand mixer bowl works well if it fits over a pot. The key is low, indirect heat and constant whisking.

Yes. Dissolve 1 full packet of Blackout instant coffee in 2 oz of hot water. Let it cool to room temperature before adding to the egg mixture. Hot liquid added too fast can begin to cook the eggs before the zabaglione is ready.

The warm version must be served immediately. It deflates as it cools and cannot be reheated. The chilled version with cream holds for up to 24 hours in the refrigerator, covered. Beyond that, the foam breaks down and the texture flattens. Make it the day you plan to serve it. See our coffee storage guide for general freshness principles.

Mousse uses whipped cream or whipped egg whites as the aerating agent , it is cold and set. Zabaglione uses the egg yolks themselves as the aerating agent, whisked hot over steam until they expand. The result is lighter and less stable than mousse, with a warm, almost drinkable consistency. Mousse holds its shape when chilled. Zabaglione does not , which is why it must be served immediately when warm. See our coffee fudge cookies guide for a richer, set coffee dessert contrast.
