  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup granulated sugar
  • 1 large egg, room temperature
  • 3 ounces plain whole milk yogurt, room temperature
  • 1/4 cup coffee, room temperature
  • 3 tablespoons flavorless oil (e.g., vegetable oil)
  • 1/2 teaspoon vanilla extract
  • 8 ounces semi-sweet chocolate bars, finely chopped
  • 2 1/4 cups heavy whipping cream, cold, divided
  • 4 large egg yolks
  • 1/4 cup granulated sugar
  • 1 teaspoon unflavored gelatin powder
  • 2 tablespoons cold water
  • 1 teaspoon vanilla extract
  • 8 ounces semi-sweet chocolate, finely chopped
  • 1 cup heavy whipping cream
  • 1 tablespoon unsalted butter, softened (optional)
  • 1 cup unsalted butter, room temperature, slightly firm to touch
  • 2 cups confectioners’ sugar, sifted
  • 1/4 cup unsweetened Dutch-processed cocoa powder
  • 23 tablespoons heavy whipping cream, room temperature
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract (optional)
  • Chocolate pearls (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line the base of an 8 or 9-inch springform pan with parchment paper.
  2. In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
  3. In a stand mixer bowl, beat the oil and sugar together until fluffy. Add in the yogurt, then beat in the egg.
  4. Alternately add the dry ingredients and the coffee to the mixture. Mix until just combined.
  5. Spoon the batter into the prepared pan and bake for 24-26 minutes. Cool in the pan.
  6. To prepare the chocolate mousse, dissolve the gelatin in cold water. In a separate bowl, whisk together the egg yolks and sugar, then combine it with heated cream. Strain the mixture and mix in the gelatin, chopped chocolate, and vanilla. Let this cool.
  7. Whip the remaining heavy cream to soft peaks and fold it into the chocolate mixture. Spread this mousse over the cooled cake and refrigerate for 4-6 hours.
  8. For the ganache, heat the cream and pour it over the chopped chocolate, then whisk until smooth. Glaze the chilled mousse cake with this mixture.
  9. For the buttercream, beat the softened butter and mix in the powdered sugar and cocoa. Frost the top of the cake.
  10. If you like, decorate the cake with chocolate pearls and serve.

Notes

Serve chilled for the best texture. Use high-quality chocolate for richer flavor and consider experimenting with different toppings.
