1️⃣ Make the chocolate ganache:
Place 4½ oz chocolate and 4½ oz heavy cream in a microwave-safe bowl. Microwave in 30-second intervals for 1-2 minutes, or until the chocolate has completely melted. Whisk together until well mixed. Set aside to cool. 🍫

2️⃣ Whip the heavy cream:
Place 1½ cups heavy cream in the bowl of a stand mixer fitted with the whisk attachment. Whisk on medium speed until stiff peaks form. Transfer whipped cream to a small bowl. 🥄

3️⃣ Make the peanut butter mousse:
Place 8 oz cream cheese, 8 oz peanut butter, 1 cup confectioner’s sugar, and ½ tsp Kosher salt in the same stand mixer bowl fitted with the whisk attachment. Whisk until very smooth and creamy. Use a rubber spatula to stir in half of the whipped cream until no streaks remain. 🍥

4️⃣ Assemble the mousse cups:
Spoon some of the ganache into cups, then divide the peanut butter mousse between them, smoothing the tops with a spatula. Place a dollop of the remaining whipped cream on top. 🥄

5️⃣ Chill, then serve:
Allow the mousse cups to chill in the fridge for at least 1 hour, then serve with chocolate shavings, crushed cookies, chopped peanut butter cups, or chopped peanuts (if desired). ❄️🍫🍪🥜
