This easy no bake chocolate mousse pie is all I have ever dreamed of; almost effortless and it still looks like you have spent hours making it!

Material & Ingredient Notes
- Oreo cookies. You can use store bought or you can make your own. You can find a great recipe here Homemade Oreos (only make the chocolate cookies, not the filling!).
- Melted butter.
- Dark Chocolate: use a good quality one, it will make all the difference. I use Valrhona chocolate and I love it.
- Heavy Cream. Make sure it has all the fat, no skimmed cream or fat-free.
- Milk. Also, no skimmed milk, please!
- Chocolate ganache: for the frosting of the chocolate pie. You can find all the details and tips on how to get a smooth chocolate ganache here.
- A 20 cm / 8-inch tart mold. I like this one.
- A food processor to pulse the cookies for. You can do this using a bag and a rolling pin if you don't have one 😉.
- A mixer or a strong arm and a whisk for whisking the cream!
How to make this recipe
Ok, now how do we make a delectable chocolate mousse pie with oreo crust? You simply:
- Make the oreo cookie crust
- Make the dark chocolate mousse filling
- Make Chocolate ganache
- Glaze the pie
- Enjoy!
Recipe notes
- The chocolate mousse must be prepared once the crust has been made and is ready to be filled.
- It must set and cool inside the pie’s shell.
- When making the chocolate mousse, the whipped cream must be folded into the chocolate ganache; once it has cooled down a little but has not started to set. The ideal temperature is 27/30 C°- 80/86 F.
- The chocolate ganache frosting is added to the chocolate mousse pie once it has been chilled and the chocolate mousse filling has set.
- This no bake pie must be enjoyed chilled! Chocolate mousse cannot be left out - it always needs to be refrigerated.
Expert notes
- When making mousse, ideally we want to mix 2 elements that have similar textures. Therefore, we add the whipped cream into the chocolate ganache in 2 steps and not all at once.
- First, add in 1/3 of the whipped cream to loosen up the ganache and make it more similar in texture to the whipped cream.
- Once it has been fully incorporated, you can fold in the remaining 2/3 of the cream, gently and lovingly!
- Ideally, let the chocolate mousse filling set overnight. If you are in a rush, 4 hours will be enough.
Making ahead
You can make this easy chocolate mousse pie up to 48 hours in advance and keep in the refrigerator without the chocolate ganache.
A few hours before wanting to eat the dessert, make the ganache and top the pie. Let it set in the refrigerator for at least 1 hour. Enjoy!
Storage tips
This chocolate mousse pie keeps for 3 to 4 days in the refrigerator. If it lasts this long 😉.
Freezer instructions
You can freeze this chocolate mousse pie,but I would recommend freezing it without the chocolate ganache frosting.
As soon as you have filled your pie tin with the chocolate mousse, cover it in saran wrap and freeze for up to 1 month.
To defrost: let it sit in the refrigerator overnight, top with the chocolate ganache and enjoy.

- 1. Make the Oreo crust: Pulse the cookies (without the filling) in a food processor until they have obtained a breadcrumb consistency. You can do this using a rolling pin too. Combine the cookie crumbs and the melted butter in a small bowl. Pour onto a greased 20 cm pie/tart tin, then press into an even layer along the bottom, making sure to get the sides, until the tin is completely covered. Refrigerate while you make the mousse.
- 2. Make the dark Chocolate Mousse Pie Filling: Whip the cream until it holds stiff peaks. Refrigerate until you are ready to use it. Bring the milk to a boil and pour over the dark chocolate chunks. Let it sit for a few minutes. Using a whisk, start mixing from the center, and as the chocolate and milk emulsify move towards the side of the bowl. Let it sit at room temperature for 5 minutes. Fold in the whipped cream in two steps - start with 1/3 of the whipped cream first, then the last 2/3 of the whipped cream. Next, fill the Oreo pie crust with the chocolate mousse. Spread evenly using an offset spatula or the back of a spoon. Refrigerate until the mousse has set; About 4 hours.
- 3. Make the Chocolate Ganache: Bring the cream to a boil and pour over the dark chocolate chunks; Let it sit for a few minutes. Using a whisk, start mixing from the center and as the chocolate and milk emulsify move towards the side of the bowl. Whisk in the cold butter.
- 4. Glaze the no bake chocolate mousse pie: Pour the ganache over the cold chocolate mousse pie. Spread evenly by moving the tin in circular directions using both hands, or by using the back of a spoon. Sprinkle with crushed Oreo cookies and let it set for 1 hour in the refrigerator.
