Ingredients Method Notes

Ingredients
  

For the crust
  • 22 pieces Oreos
  • 5 tbsp melted butter
For the mousse filling
  • 12 oz cream cheese, room temperature
  • 1.5 cups smooth peanut butter
  • 1.5 cups powdered sugar
  • 0.5 tsp vanilla extract
  • 0.25 tsp salt
  • 1.5 cups heavy cream, cold
For the ganache
  • 4 oz semisweet chocolate, chopped
  • 0.5 cup heavy cream
For topping (optional)
  • Peanut butter cups For garnish on top

Method
 

Preparation
  1. In a food processor, combine the Oreos and melted butter until a fine crumb forms. Press this mixture into the bottom and sides of a pie tin and refrigerate while you prepare the filling.
  2. In a large bowl, beat the cream cheese until fluffy. Add the peanut butter, powdered sugar, vanilla, and salt; mix until smooth. Then, add the cold heavy cream and whip until light and fluffy.
  3. Pour the mousse into the prepared crust, smoothing the top with a spatula. Chill in the fridge to firm up for about 2-3 hours.
Ganache preparation
  1. Heat 1/2 cup of heavy cream until steaming, then pour it over the chopped chocolate. Let it sit for a moment before whisking until it’s silky smooth.
  2. Pour the ganache over the set mousse and smooth it out. Top with optional peanut butter cups if desired.
  3. Chill again until set, about 30 to 60 minutes.

Notes

For an extra touch, add a sprinkle of sea salt on top of the ganache before chilling. Mix crushed peanuts into the mousse for added texture. Store leftovers covered in plastic wrap in the refrigerator for a few days.
