FAQ

Can I make this without the Oreo crust?

Yes, simply skip the cookie layer and start with the fudge sauce directly in the dishes for a lighter version.

What if I don't have an electric mixer?

You can whip cream by hand with a whisk, though it takes more effort. The cream cheese mixture may be lumpy without a mixer.

How long will this keep in the refrigerator?

The mousse will keep for up to 3 days covered, but the texture is best within the first 24 hours.
