    Step by Step Instructions

    Here are step by step photos and instructions on how to make this no-bake chocolate mousse pie recipe! For the full ingredient list and method, see the recipe card at the end of this post.

    crushed Oreos inside a food processor on a marble table.
    STEP 1
    Oreo pie crust pressed into a white pie plate.
    STEP 2

    STEP 1: Make the crust. In a food processor, add the Oreos and pulse until they become fine cookie crumbs. Add the melted butter and mix until combined.

    STEP 2: Press and freeze. Press the Oreo mixture into the bottom and sides of a 9” pie pan, packing it in with the back of a spoon or a small cup. Place the Oreo cookie crust in the freezer while you make the chocolate mousse filling.

    STEP 3

    STEP 4

    STEP 3: Whisk egg yolks and sugar. In a medium mixing bowl, whisk together the room temperature egg yolks and 66g (⅓ cup) sugar until it's pale in color and flows off of the whisk. Then, place over a small pot of simmering water, whisking frequently until it reaches 160 F. 

    STEP 4: Melt chocolate and add vanilla. Turn the heat down to low and mix in one teaspoon vanilla extract and 8 ounces of chocolate until fully melted. It will turn into a thick, fudge-like consistency. Set aside to cool for a few minutes.

    STEP 5
    whipped meringue with stiff peaks in a glass bowl.
    STEP 6

    STEP 5: Cream. In the bowl of a stand mixer fitted with the paddle attachment, cream 8 tablespoons of butter on medium speed for 2-3 minutes until light and fluffy. Add in the egg yolk, chocolate mixture, then turn the mixer up to high speed for about 3 minutes until fluffy. Don’t worry if it starts to split, it will all come together once the meringue is added!

    STEP 6: Make the meringue. In a separate heat safe bowl, whisk together the egg whites and remaining sugar. Place over a small pot of simmering water, whisking frequently until it reaches 160 F. Remove the bowl from heat and use an electric hand mixer to beat until stiff peaks form.

    STEP 7: Fold. Gently fold the meringue into the into the chocolate mixture until no white streaks are left. 

    STEP 8: Pour and chill. Pour the chocolate mousse filling into the Oreo crust and smooth out the top with an offset spatula. Place in the fridge to chill for at least 3 hours or overnight.

    STEP 9

    STEP 10

    STEP 9: Make the whipped cream. Just before serving the pie, make the whipped cream. In a large measuring cup or bowl, add the cold heavy whipping cream and sugar. Use an electric mixer to whip the cream until stiff peaks form. Careful not to over-whip the cream, as it can quickly split and become grainy!

    STEP 10: Top and serve. Top the pie with the whipped cream, and add chocolate shavings, if desired. Enjoy!

    Expert Baking Tips

    • If you don't have a food processor, crush the Oreos with a rolling pin. Place the Oreos in a double lined ziplock bag, and use a rolling pin to crush them into fine crumbs! Then pour them into a bowl, and stir in the melted butter. 
    • Separate the eggs with your hands. The best way to separate an egg and ensure the egg yolk doesn't break is to crack the egg into a shallow bowl, then pick up the egg yolk with your hands. The egg white will easily pull away from the yolk, which you can then place into another bowl.
    • Don't over-whip the cream! Whip the cream to until it just reaches stiff peaks. Cream can split very quickly and become grainy.
    • Assemble the pie just before serving. Whipped cream can liquify again, so I recommend waiting to whip the cream and assembling the pie until just before serving.

    Recipe FAQs

    Can I use store-bought pie crust?

    Of course! But if you have the time, I encourage you try homemade. It's so much better than store-bought, and it is surprisingly easy to make!

    What do I do if my whipped cream gets grainy?

    If you over-mix the whipped cream, it can split and become grainy. Adding a few small spoons or a slow drizzle of heavy cream while slowly mixing should get it smooth again.

    Make-Ahead Tips

    You can make the Oreo crust and the chocolate mousse filling a day ahead of serving–just store the assembled pie, covered, in the fridge. You don't have to make the whipped cream until immediately before serving!

    Storage Tips

    Store leftover pie slices covered in the fridge for 2-3 days.

    Baking in Grams

    All of the recipes on this blog are carefully developed with gram measurements so you can easily recreate them in your own kitchen with success. Volume measurements are extremely inaccurate and leave room for significant errors. Not all measuring cups are made equally, so your one cup of flour will be different from my one cup of flour. By providing precise measurements in grams (aside from minor ingredients, which are given in tsp/tbsp), you can make these recipes accurately and with less cleanup! All you need is this kitchen scale. 

    If this still isn't enough to convince you, I have provided volume measurements in the recipe card. If you are interested in understanding the conversions, this is the best conversion chart.

    But trust me, once you try baking in grams you'll never turn back!

    Happy baking! x
