# What You Need:

→ Chocolate Espresso Mousse

01 - 7 ounces bittersweet chocolate (at least 60% cocoa), chopped
02 - 2 teaspoons instant espresso powder
03 - 2 tablespoons hot water
04 - 3 large eggs, separated
05 - 1/4 cup (1.8 ounces) granulated sugar
06 - 1 cup heavy whipping cream
07 - 1 teaspoon pure vanilla extract
08 - Pinch of salt

→ Garnish

09 - Sweetened whipped cream, as needed
10 - Chocolate shavings or cocoa powder, as needed
11 - Espresso beans, as needed

# How to Make It:

01 - Dissolve the instant espresso powder in hot water, stirring thoroughly. Set aside and allow to cool completely.
02 - Place the chopped chocolate in a heatproof bowl set over a saucepan of barely simmering water. Stir gently until completely smooth and glossy. Remove from heat.
03 - Pour the cooled espresso concentrate into the melted chocolate and stir until uniformly blended. Allow the mixture to cool to lukewarm temperature.
04 - In a clean mixing bowl, beat the egg yolks with half of the sugar until the mixture turns pale and thickens slightly. Add the vanilla extract and blend thoroughly. Gently fold this yolk mixture into the lukewarm chocolate espresso base.
05 - In a separate chilled bowl, whip the heavy cream to medium peaks using an electric mixer or whisk. Set aside in the refrigerator.
06 - In a clean, dry bowl, beat the egg whites with a pinch of salt until soft peaks begin to form. Gradually sprinkle in the remaining sugar while continuing to beat until glossy, stiff peaks hold their shape.
07 - Gently fold the whipped cream into the chocolate mixture using a rubber spatula. Then carefully fold in the beaten egg whites in three additions, preserving as much air as possible, until no white streaks remain.
08 - Spoon or pipe the finished mousse evenly into 6 individual serving cups or glasses, smoothing the tops.
09 - Cover the cups loosely with plastic wrap and refrigerate for at least 2 hours, or until the mousse is fully set and firm.
10 - Just before serving, dollop whipped cream on top of each cup and finish with chocolate shavings, a dusting of cocoa powder, or a few espresso beans as desired.

# Expert Tips:

01 -
  • The espresso does not make it taste like coffee, it makes the chocolate taste more like itself, and that is a revelation worth sharing.
  • You can make them a full day ahead and they only get better, which means zero stress when guests arrive.
02 -
  • If even a drop of yolk gets into your egg whites or your bowl has residue, they will not whip, so wash everything with hot soapy water first.
  • Folding is not stirring, you want to cut down through the center and sweep up the sides, and stopping slightly before you think it is fully mixed keeps the mousse light.
03 -
  • Chill your mixing bowl and whisk in the freezer for ten minutes before whipping cream, and it will reach perfect peaks in half the time.
  • If you want a caffeine free version, decaffeinated espresso powder works beautifully and no one will notice the difference.
