Mile-High Chocolate Mousse Pie is so thick. So rich. So indulgent. It’s a classic chocolate mousse piled high in an Oreo crust and topped with a mountain of sweet and creamy whipped cream. This is a heavenly treat that can’t be beat. Try it, you’ll see.

How do you like your crust?
This Chocolate Mousse Pie starts out with an Oreo Cookie Crust.
You can buy a pre-made crust from the grocery store or you can make your own. I’ve made my own and I’ve bought a pre-made crust.
I usually use a pre-made crust if I’m taking the pie somewhere so that it’ll be in a disposable pan.
If you choose to bake your own, the basic recipe for an Oreo Cookie crust is 25 Oreos + 5 Tbsp melted butter.
Finely crush up the cookies (make it easy on yourself and use your food processor!) then mix with the butter and press into the pan.
If you’d like, you can bake the crust at 325 degrees F for about 7 minutes but it’s not necessary with an Oreo cookie crust.
Miles of Mousse
The chocolate mousse is a classic mousse recipe made with eggs and cream.
The key here is to keep the egg whites and the heavy cream cold then carefully fold them into the chocolate mixture.
You want to be gentle so that you don’t deflate the mousse.
If you use cold ingredients, your mousse should firm up quickly and you can go ahead and pile that mousse high in your Oreo Cookie crust.
You’ll want to chill the chocolate mousse in the crust in your refrigerator for at least an hour until it’s completely firm before you add your whipped topping.
Light and Fluffy Whipped Cream
Again, you’ll want your heavy whipping cream and your mixing bowl and beaters to be very cold before you whip up your whipped cream.
Whip, whip, whip.
A cup of heavy whipping cream is plenty if you’re just spreading over the top of your pie.
You’ll want to make more if you’re doing any sort of fancy piping or decorating with it.
This pie is so delicious and it just cuts beautifully. It always gets rave reviews. The only thing I wish … is that it was bigger!

Heavy cream doesn't usually form peaks. Then you say to also use whipping cream. Are you using the two types of cream or just calling heavy cream by the wrong name? There is heavy cream and there is whipping cream. Plz advise.

This recipe uses heavy whipping cream, also called heavy cream. It’s essentially the same thing. The carton I get at the grocery store is labeled heavy whipping cream. Hope this helps.
