Step‑by‑Step Instructions for Chocolate and Peanut Butter Mousse Cheesecake
Step 1: Prepare the Oreo Crust
Begin by crushing about 24 Oreo cookies into fine crumbs using a food processor or a plastic bag with a rolling pin. Melt 1/2 cup of butter and mix it into the cookie crumbs until well combined. Firmly press this mixture into the bottom of a 9-inch springform pan to create an even layer. Chill the crust in the refrigerator for at least 15 minutes to set while you prepare the mousse layers.
Step 2: Make Peanut Butter Mousse
In a mixing bowl, beat 8 ounces of softened cream cheese with 1/2 cup of peanut butter and 1 cup of confectioners’ sugar until smooth and creamy. In a separate bowl, whip 1 1/2 cups of heavy whipping cream to stiff peaks. Gently fold the whipped cream into the peanut butter mixture until well combined. Once fully blended, spread this luscious peanut butter mousse evenly over the chilled Oreo crust, ensuring a smooth top.
Step 3: Make Chocolate Mousse
Melt 4 ounces of bittersweet chocolate and 2 ounces of milk chocolate together in a microwave or over a double boiler until smooth. In a small saucepan, heat 1/3 cup of sugar with 1/3 cup of milk until dissolved. Allow the chocolate to cool slightly, then combine it with the milk mixture. In another bowl, whip the remaining 1 1/2 cups of heavy whipping cream to stiff peaks, then fold it into the chocolate mixture. Carefully spoon this chocolate mousse over the peanut butter layer and refrigerate for at least 2 hours to allow it to set.
Step 4: Prepare Ganache Topping
To make the ganache topping, heat 1 cup of heavy cream in a small saucepan until it begins to boil. Pour the boiling cream over 6 ounces of chopped semi-sweet chocolate, letting it sit for a minute to melt. Stir until smooth, then mix in 1 teaspoon of vanilla extract. Once the chocolate ganache is slightly cooled, pour it over the chilled chocolate mousse layer, spreading it evenly. Chill the cheesecake for another hour until the ganache is fully set.
Step 5: Serve
Remove the cheesecake from the springform pan by running a knife around the edge for a clean release. Slice the decadent Chocolate and Peanut Butter Mousse Cheesecake using a hot knife for perfect cuts. Serve as is or enhance it with a drizzle of caramel or chocolate sauce and fresh berries for a delightful presentation. Enjoy the satisfying layers of creamy mousse and crunchy crust!

Make Ahead Options
These Chocolate and Peanut Butter Mousse Cheesecake are perfect for meal prep enthusiasts! You can prepare the crust and mousse layers up to 24 hours in advance to save time on the day you plan to serve. Make sure to refrigerate the crust immediately after pressing it into the pan, and keep the mousse layers separate until you’re ready to assemble. Once you layer the peanut butter mousse over the crust and chill for a couple of hours, finish with the chocolate mousse layer and chill again for at least 2 hours. This allows the flavors to meld beautifully, ensuring your cheesecake is just as delicious when served later. Simply add the ganache topping shortly before serving for that fresh, decadent finish!
Expert Tips for Chocolate and Peanut Butter Mousse Cheesecake

- Chill Thoroughly: Refrigerate your cheesecake for at least 4 hours or overnight. This allows flavors to meld and the mousse to set perfectly, enhancing the overall experience.
- Customizable Crunch: Feel free to add crushed nuts or pretzels to the crust for a delightful texture twist in your Chocolate and Peanut Butter Mousse Cheesecake.

Chocolate and Peanut Butter Mousse Cheesecake Recipe FAQs
What type of Oreo cookies should I use?
Absolutely, using classic Oreo cookies for the crust provides the perfect chocolatey base. If you want to mix it up, chocolate wafer cookies can also offer a similar flavor profile. Just make sure to crush them into fine crumbs for a better texture!
How should I store leftovers?
Store any leftover Chocolate and Peanut Butter Mousse Cheesecake covered in the refrigerator for up to 4 days. I recommend wrapping it tightly in plastic wrap or placing it in an airtight container to maintain its freshness and flavor.
Can I freeze the cheesecake?
Very! You can freeze slices of the cheesecake for up to 2 months. To do this, wrap each slice individually in plastic wrap, then place all slices in a freezer-safe bag or container. When you’re ready for a sweet treat, simply transfer the wrapped slices to the refrigerator to thaw overnight.
What if my mousse layers aren’t setting?
If your mousse layers aren’t setting, make sure you’re using the correct temperatures and whipping your cream to stiff peaks. Sometimes, if the cream cheese isn’t softened sufficiently, it can lead to lumps and a denser mouse. Whipping the heavy cream longer can help achieve that light texture. Remember, patience and proper chilling time are key!
Is this recipe suitable for those with nut allergies?
If anyone you’re serving has nut allergies, I would recommend avoiding the peanut butter altogether. You can replace it with sun butter (sunflower seed butter) or even omit it entirely for a delicious chocolate mousse cheesecake that still satisfies! Always double-check with guests if allergies are a concern.
How can I enhance the flavor of the cheesecake?
One great way to enhance the flavor is to experiment with different extracts. If you’re feeling adventurous, try adding some almond extract to the mousse layers or mixing in some espresso powder to the chocolate mousse for a mocha twist. The more the merrier when it comes to customizing your cheesecake!
