Whip up this chocolatey, decadent dessert in a few minutes with just two ingredients!
In a microwave-safe bowl, heat 1/2 cup of the heavy cream for 50 seconds (depending on microwave strength).
Add the chocolate chips to the cream and stir until the chocolate has melted. This will take 1-2 minutes. Set aside to cool.
Pour the remaining 1 cup of heavy cream into a medium bowl. Using a hand-held or stand mixer, beat until soft peaks form. (Optional: Store half the soft whipped cream into a small bowl and refrigerate it to use as a topping for the mousse.) Continue whipping the cream until stiff peaks form.
Slowly fold in half the whipped cream into the chocolate mixture with a large spatula. Gently fold in the rest of the whipped cream.
Divide the mixture between 4 ramekins or cocktail glasses (I used lowball glasses). Refrigerate for at least one hour, (up to overnight), before serving. Top with the reserved whip cream or cool whip and chocolate shavings.
