What Is My Take on No Bake Chocolate Mousse Pie with Oreo Crust
This pie is the ultimate “I want something decadent but also want to stay in my pajamas” dessert. I absolutely love how effortlessly impressive it is—like, you made mousse? Yes. Yes we did. But we made it in the laziest, most delicious way possible.
The streaks of chocolate in the cream, the fluffy egg whites folded just right, the cold whip on top… It’s giving restaurant-quality without restaurant-effort.
Make it a Meal
If you want to serve this as the grand finale of an epic dinner, pair it with something equally delicious like:
- Grilled Cornish Game Hens
- Instant Pot Beef Short Ribs
- Spicy Kung Pao Chicken
- Bulgogi Beef Korean Pizza
Anything savory and satisfying works beautifully before this chocolate masterpiece makes its entrance.
Easy Side Dishes
If you’re keeping things simple, try pairing your main dish with:
- Southern Green Beans
- Air Fryer Brussels Sprouts
- Simple Fried Rice
- Roasted Carrots with Honey & Spice
Nothing too heavy—you want to save room for pie!
Ingredients
It's very important to use unsweetened baking chocolate in this recipe. I like to use a good quality baking chocolate like Bakers or Ghirardelli unsweetened baking chocolate.
- Unsweetened baking chocolate
- Sugar
- Egg whites - preferably room temperature for best results
- Cream of Tartar - helps the egg whites to hold air better
- Heavy cream
- Butter - Unsalted
- Oreo cookies
Step By Step Instructions
The base of the chocolate mousse pie is an Oreo crust. This crust is so easy to make and just incredibly delicious!
How to Make an Oreo Crust
Step 1: Preheat the oven to 350F degrees.
Place the Oreo cookies in a food processor and pulse until crumbs are formed. It should be pretty fine, you don't want big chunks of Oreo or your crust will not be uniform.
Step 2: Pour the crumbs in a bowl and mix in the melted butter.
Step 3: Press the mixture firmly into pie plate (your fingers are best for this) and bake at 350 degrees for 18 minutes. Refrigerate until it's cooled.
How to Make Chocolate Mousse
Step 1: The chocolate fluff is the most labor intensive part of this recipe. And it's not that hard. Start by using a knife to roughly chop the chocolate.
Step 2: Melt the chopped chocolate and butter together in a heatproof bowl. I typically use the microwave for this as it is the quickest and easiest way.
Step 3: Place whipping cream in a bowl and whip until soft peaks form. Slowly fold in the melted chocolate. The mixture doesn't have to be fully combined at this point - streaks are ok.
Step 4: Gently fold the melted chocolate into the whipped cream. Be careful not to over-mix it.
Step 5: Place the egg whites in a bowl and whip until frothy.
Step 6: Add the cream of tartar and ¼ of the sugar and continue whipping, adding a little sugar at a time, until soft peaks form.
Step 7: Gently fold the egg whites into the chocolate mixture, being careful not to over-mix or the egg whites will deflate. The mixture should be fluffy when you're done. Read this post on how to fold egg whites from The Kitchen.
Step 8: Pour the chocolate mousse into the cooled pie crust and refrigerate for 4 hours, or until completely set.
Step 9: Spread the whipped cream on (see instructions for making whipped cream in the next paragraph) and refrigerate another hour until whipped cream is set. Garnish with chopped chocolate and serve.
How To Make Whipped Cream
Step1: Whip the cream until it starts to become frothy.
Step2: Add the sugar and vanilla and continue beating until soft peaks form.
Step2: Spread the whipped cream over the cooled chocolate mousse. Refrigerate 1 hour and serve.
Expert Tips
- Be careful not to over beat the whipping cream or it will become watery and you'll have to start over.
- Let the egg whites come to room temperature before whipping them - they will whip better.
- Let the crust cool fully before adding the mousse. A warm crust could cause the mousse to start to deflate. I typically place the crust in the freezer for about 20 minutes before adding the mousse.
- Whenever you are mixing something with egg whites, be sure to fold the mixture together, don't just mix it. Read this post on how to fold egg whites from The Kitchn.
- Cool the pie fully before serving. If you serve when it's warm, it will be very messy (but will still taste good ;-).
Common Questions
If you over beat the whipping cream, it will become watery. Make sure to stop beating once soft peaks have formed. If you over beat, you have to start from scratch.
If there is any egg shell, egg yolk, or any foreign matter it may cause the egg whites to not whip. In addition, room temperature egg whites will whip up easier than cold egg whites. The cream of tartar will also help to keep the air in the egg whites.
Chocolate mousse pie can be made from 2 hours to 3 days in advance. Store in the fridge, covered loosely with plastic wrap or foil until ready to serve. It will last in the fridge for 3-4 days.
Absolutely—it won’t be quite as airy, but it works!
Storing Instructions
Cover the pie loosely with plastic wrap and store it in the refrigerator for up to 4 days.
Chocolate mousse pie can also be stored, covered, in the freezer for up to 1 week. If you want to keep it longer, place it in an airtight container and freeze for up to 1 month for the best results. Just thaw in the refrigerator before serving.

I made this pie and everything was delicious except the crust😩. We tried to cut it the next afternoon but the crust was like a brick. Finally after almost cut the pie pan I was able to take a bite of the crust good but so chewy
Danielle says
Oh no, I'm so sorry the crust came out so hard! I haven't had that issue before, I will have to ponder what could have happened and update the post with tips 🙂
Julie says
Going to make this for our “different” Thanksgiving this year. Going to use a regular pie crust. Oreo is a little sweet overkill for me.
Danielle says
I totally get it, Oreo can be really sweet - I really hope you enjoy it!
Sheila says
Do you use salted or unsalted butter?
Danielle says
Salted - thanks for pointing out that I didn't specify that!

Okay, I have not made this yet, but I gave it a five star rating already anyway, because every recipe of yours that I have tried has turned out perfectly delicious! I swear, I almost licked the screen when reading through this recipe. But, I got sidetracked and clicked on the link to your oreo balls as well. I have to come back to finish reading the chocolate pie recipe. Oops!
Danielle says
LOL! Thanks so much Byron! There's nothing quite like no bake chocolate desserts, right???
