How to Make Coffee Mousse
See the recipe card further down for exact measurements and timing.
- Beat egg yolks: In a medium bowl, beat egg yolks on high with an electric mixer until pale and fluffy, about 3 minutes.
- Add dry ingredients: Mix in powdered sugar, espresso powder and cocoa powder until combined.
- Heat cream: Warm 1 cup of heavy cream over medium heat until hot and steaming but not boiling.
- Temper the eggs: Slowly pour hot cream into the egg mixture while whisking constantly to prevent curdling.
- Thicken: Return the mixture to the saucepan and cook over low heat, stirring, until it coats the back of a spoon (about 5 minutes). Do not boil. Transfer to a large bowl to cool, then refrigerate until cold.
- Whip cream: Whip the remaining cold heavy cream until stiff peaks form. Reserve a small amount for garnish if desired.
Pro tip: Speed cooling by placing the bowl in the freezer and stirring every 5 minutes until cool (about 15–20 minutes).
- Fold together: Gently fold the whipped cream into the cooled coffee-cocoa mixture using a rubber spatula until evenly combined.
- Chill and serve: Spoon into a large bowl or individual ramekins (or pipe for a neater look). Refrigerate at least 4 hours to set. Garnish with whipped cream and a dusting of espresso or cocoa powder, or a few coffee beans.
Serving Suggestions
Serve cold with fresh fruit, biscuits, cookies or wafers. This mocha mousse also makes a luscious cake filling or topping for pastries.
Top Tips
- Temper eggs properly: Add hot cream slowly while whisking to avoid curdling.
- Cool completely: Allow the custard to chill fully before folding in whipped cream so it stays light.
- Chill before serving: Refrigerate for at least 4 hours for best texture and flavor development.
- Garnish ideas: Top with whipped cream, cocoa or espresso powder, chocolate shavings, or chocolate-covered strawberries.
Coffee Mousse FAQs
Egg yolks act as an emulsifier and provide structure, giving the mousse its creamy, stable texture.
It will firm as it chills. If still too loose after chilling, longer refrigeration or slightly more whipped cream folded in can help. Ensure the custard was thickened properly on the stove.
No; fresh grounds won’t dissolve. Use instant espresso powder or finely ground instant coffee for the best result.
Cover and refrigerate in an airtight container for 2–3 days.
