Instructions
 

Chocolate Cake

  • Preheat oven to 350° F
  • Prepare a 9" springform cake pans by lining the bottom with parchment paper or greasing the pans.
  • Combine flour, sugar, cornstarch, salt, baking powder and baking soda in the bowl of a stand mixer. If mixing by hand or with a hand mixer, combine ingredients in a large mixing bowl.
  • Add oil and eggs and mix until combined.
  • Slowly pour brewed coffee into bowl while continuing to mix, scraping the bowl occasionally. The batter should be smooth.
  • Bake for 28 – 30 minutes, or until a toothpick inserted in the center of the cake comes out clean.
  • Place cakes on a rack and allow to cool completely.

Make the Caramel Mousse

  • Sprinkle powdered gelatin over cold water. Set aside to allow to gel.
  • Lightly whip egg yolks in a bowl, set aside.
  • Place granulated sugar in a heavy-bottomed sauce pan.
  • Begin heating the sugar on medium heat and allow to come to a boil. Do not stir sugar.
  • Continue boiling sugar until it turns an amber color.
  • Turn heat to low and add butter and heavy cream (measure #1). Use caution as the mixture may sputter. Stir until the butter is melted.
  • Remove from heat and add white chocolate and gelatin. Stir until melted.
  • Temper the egg yolks by slowly pouring ¼ of the caramel sauce into the eggs, whisking constantly to prevent eggs from curdling.
  • Place sauce pan on stovetop over low heat. Whisking constantly, pour the tempered eggs gradually into the saucepan. Whisk vigorously until the mixture thickens slightly and reaches 160° F.
  • Pour mixture into a large bowl and set aside to allow to cool completely (approximately 30 minutes).
  • Begin whipping heaving cream (measure #2) to medium peaks.
  • Gently fold into caramel mixture.

Simple Syrup

  • Combine granulated sugar and water in a saucepan. Heat over medium heat until sugar is dissolved and the water is just beginning to boil. Set aside to cool.

Assembling the Cake

  • Poke holes in the chocolate cake with a dinner fork. Evenly brush the cooled simple syrup over the cake.
  • Pour the caramel mousse over the chocolate cake in the springform pan. Smooth the top with an offset spatula. Tap gently on the counter to release any air bubbles.
  • Place cake in refrigerator for 2 hours or until mousse is fully set.

Unmold the Cake

  • Dip a knife or offset spatula into a cup of hot water and run the knife around the inside of the springform pan. Gently release the spring on the pan and move to a serving dish.
