Instructions

  1. Step 1: In a large mixing bowl, beat 4 oz cream cheese with 1/2 cup creamy peanut butter and 3/4 cup powdered sugar using an electric mixer on medium speed until smooth and creamy, about 2-3 minutes.
  2. Step 2: In a separate chilled bowl, whip 1 cup heavy cream with 1 tsp vanilla extract and 1/8 tsp salt until stiff peaks form, about 4-5 minutes on high speed.
  3. Step 3: Gently fold the whipped cream into the peanut butter mixture in three additions until fully combined and airy.
  4. Step 4: In a small microwave-safe bowl, combine 6 oz semisweet chocolate chips and 2 tbsp unsalted butter; microwave in 30-second intervals, stirring between each, until smooth and glossy.
  5. Step 5: Spoon half of the peanut butter mousse into serving glasses, then layer with half of the warm chocolate ganache. Repeat layers, finishing with ganache on top. Chill for at least 1 hour before serving to set.
