How to Make It

Let’s get started on creating this delightful dessert!

1. Combine crust ingredients.

In a bowl, combine graham cracker crumbs and melted butter. Press mixture into the bottom of a 9×13 inch pan to form the crust.

2. Prepare the peanut butter mousse.

In another bowl, beat the peanut butter and powdered sugar until smooth. In a separate bowl, whip the heavy cream with vanilla extract until soft peaks form.

3. Fold whipped cream into peanut butter.

Gently fold the whipped cream into the peanut butter mixture until combined. Spread the peanut butter mousse over the graham cracker crust.

4. Make the ganache.

To make the ganache, heat 1/2 cup heavy cream until just simmering, then pour over the chocolate chips in a bowl. Let sit for a few minutes, then stir until smooth.

5. Pour ganache over mousse.

Pour the ganache over the mousse and spread evenly.

6. Refrigerate to set.

Refrigerate for at least 4 hours or until set. Slice and serve.
