PEANUT BUTTER CHOCOLATE MOUSSE CAKE

If I could give this recipe six stars i would. I made this cake for my finance’s birthday, and he loved it! The cake was sooo moist, and the frosting was absolutely delicious. I did take the advice of adding the eggs after the hot ingredients are added to dry. I used crunchy peanut butter and it was great! I will defiantly make this again.

it’s very moist and goey in the centre, and the icing is quite something! I got away with much less, thou, beacause they seem not to appreciate too strong an icing presence around here. Fabulous indeed!

NOTE: A 9 inch springform pan is best for this recipe so that you can easily remove the cake once it’s been assembled.

BROWNIE:
  • Make brownie dough according to instructions on back of box.
  • Grease a 9 inch pan (preferably springform pan, see above) and line the bottom with parchment paper to allow for easy removal. Pour brownie batter into pan and bake according to box instructions.
  • When brownie is done baking, remove from pan and allow to completely cool.
  • Once brownie has cooled, place brownie back into the bottom of the springform pan. Line the sides of the pan with parchment paper that sticks a few inches above the top edge of the pan.
  • Top brownie with an even layer of mini Reese’s. Set aside.

TO MAKE PEANUT BUTTER MOUSSE:
  • In a small bowl, sprinkle the gelatin over the water, let stand for about 5 minutes.
  • Place the peanut butter chips in a medium bowl
  • Microwave 3/4 cup of heavy cream until it comes to a full boil.
  • Add gelatin mixture to the heavy cream and whisk until dissolved.
  • Pour cream over the peanut butter chips and let sit for about a minute.
  • Whisk until peanut butter chips are melted and mixture is smooth. Set aside, cooling for about 5 minutes.
  • Whisk remaining 1 1/2 cups heavy cream at high speed with a mixer until it begins to thicken.
  • Add powdered sugar then continue to whip until stiff peaks form.
  • Fold about a third of the whipped cream to the lightly cooled peanut butter mixture until well combined.
  • Add remaining whipped cream and fold in until well combined.
