1-Step 1: Prepare the Chocolate Ganache Begin with the chocolate ganache by placing the chopped dark chocolate in a medium heat-proof bowl. Heat the heavy cream in a small saucepan over medium heat until it just starts to boil, then pour it over the chocolate right away. Let it sit for 1 minute, then whisk gently until it’s smooth and glossy. Allow the ganache to cool slightly before using.

2-Step 2: Make the Peanut Butter Mousse Next, for the peanut butter mousse, beat the cream cheese, peanut butter, powdered sugar, and vanilla extract together using a mixer with the paddle attachment until it’s fluffy and smooth. In a separate bowl, whisk the heavy cream until stiff peaks form, which gives the mousse its light texture.

3-Step 3: Combine and Assemble Gently fold half of the whipped cream into the peanut butter mixture, then add the rest to keep it airy. Now, layer the peanut butter mousse and chocolate ganache in jars or cups for your parfaits. You can include optional layers like chopped peanuts or brownie pieces between them for extra flair.
