FAQs
Q: Can I make parts ahead?
A: Yes. You can make the crust and brownie layer a day ahead. Store covered in the fridge and add the mousse and whipped cream the next day.
Q: Can I use a store-bought chocolate mousse?
A: Yes. A good store-bought mousse works if you want faster prep. Just spread it over the cookie topping and chill.
Q: Is this pie safe to make without baking the brownie layer?
A: The brownie layer uses eggs, so it needs baking. Do not skip baking unless you use a safe, no-bake brownie substitute.
Q: Can I use a springform pan instead of a pie pan?
A: Yes. A 9-inch springform pan works well. It may be easier to remove the pie whole for serving.
