How to Make Double Chocolate Mousse Cake

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
  3. In a separate bowl, cream together the butter and sugar until light and fluffy.
  4. Beat in the eggs one at a time, then stir in the vanilla extract.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  6. Stir in the melted chocolate chips and hot water.
  7. Pour batter into the prepared pan and bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
  8. Let the cake cool completely in the pan before frosting.
  9. Meanwhile, prepare the chocolate mousse: In a large bowl, beat the heavy cream until stiff peaks form.
  10. In a separate bowl, whisk together the powdered sugar, cocoa powder, and melted chocolate until smooth.
  11. Gently fold the whipped cream into the chocolate mixture until combined.
  12. Once the cake is cool, frost the top with the chocolate mousse and refrigerate for at least 2 hours before serving.
