And have I got a magical dessert for you, my friends. Peanut butter mousse brownie pie is a dessert to be shared amongst those you love the most, but it’s so good I won’t blame you if you want to keep it all to yourself.

If that’s not heaven on a plate, I don’t know what is. 

    Peanut Butter Mousse Brownie Delight

    Heaven on a plate...and in your mouth!

    Servings: 6-8


    • high quality brownie mix: 1 box
    • creamy peanut butter (not the natural kind): 3/4 cup
    • cream cheese: 4 ounces at room temperature
    • vanilla: 1 teaspoon
    • milk: 3 tablespoons
    • powdered sugar: ½ cup
    • heavy cream: 2/3 cups, cold
    • large peanut butter cups: 3 to 4, cut in half
    • peanuts: ½ cup, coarsely chopped
    • chocolate syrup: for drizzling


    Step 1: Mix brownies according to package instructions. Butter and flour/cocoa powder an 8-inch springform pan and pour brownie batter in. Bake according to the package specifications. When finished baking, remove from oven and allow to cool while you make the mousse.


    Step 2: To make the mousse: Place peanut butter, cream cheese, vanilla, and milk into the bowl of a mixer. Beat on high until light and creamy, about 5 minutes. Turn off mixer and add in powdered sugar. Start the mixer on low and slowly increase to high. Beat until smooth and fluffy, about 2 minutes. Set aside. 


    Step 3: Place heavy cream into a clean mixing bowl. Using the whisk attachment beat the cream until stiff peaks form, about 2--3 minutes.  


    Step 4: Working in three batches, gently fold the whipped cream into the peanut butter mixture using a rubber spatula. Do not rush this process. You want to keep as much air in the mousse as possible. Place mousse into a large Ziplock bag and refrigerate for 1 hour.



    Step 5: When ready to serve, cut the brownie pie into slices. Cut a small hold in the corner of the Ziplock bag holding the mousse and pipe a small amount onto each slice. Garnish each slice with half a peanut butter cup, crushed peanuts, and a drizzle of chocolate syrup.
