Mississippi Mud Pie layers coffee-infused flourless chocolate cake, chocolate pudding, and whipped cream in an Oreo crust for a truly impressive dessert!
Old-Fashioned Mississippi Mud Pie Recipe
If you’re the type that likes to scroll down to see the recipe before reading the rest of the blog post, you’ll notice that this Mississippi Mud Pie is a lot. A lot of chocolatey goodness, a lot of layers, and, yes, a lot of work.
Nope, I’m not going to lie to you—this is the kind of recipe that takes some effort. But you’ll be richly rewarded with a classic Mississippi Mud Pie. No shortcuts, no compromises.
So, here’s what we have. First, there’s the amazing Oreo crust, which is sufficiently thick to hold up all of this deliciousness. Next is a flourless chocolate cake with just the right amount of coffee flavor. To top that off, there’s a chocolate pudding that would be an impressive dessert on its own. Then, just in case all that isn’t enough, there’s a lovely, thick layer of sweetened whipped cream on top.
Before you get discouraged, I should tell you that there is nothing difficult about making Mississippi Mud Pie. It is certainly time-consuming and a labor of love. The crust and cake layer can easily be made a day in advance. This leaves the pudding layer and the whipped cream for the next day. (That also leaves your sanity mostly intact.)
Every minute spent making this cake/pie/pudding is definitely worth it. Bookmark this one for a special occasion. Make up an occasion if necessary. It’s just that good.

What Can You Substitute for Kahlua?
If you prefer not to use Kahlua in your Mississippi Mud Pie, you can substitute a strongly-brewed coffee. Let it come to room temperature before adding it to the other ingredients.
How to Make Mississippi Mud Pie
Be sure to plan for each step of the recipe so you have ample time to put everything together. Here’s what you’ll need to do.
Make the crust:
Prepare. Preheat your oven to 300°F and lightly spray a 9-inch springform pan with nonstick cooking spray. Line the pan with parchment paper, then spray the parchment and the sides of the pan.
Make the crust mixture. Place the Oreos in a food processor and pulse them until a fine crumb forms. Transfer the crumbs to a small bowl, then stir in the melted butter.
Form the crust. Use the back of a spoon or your hands to press the crumb mixture into the bottom and up the sides of the prepared pan. Freeze for 10 minutes.
Bake. Remove the pan from the freezer and bake the crust for 10 minutes, or until it is dry to the touch. Cool the crust in the pan on a wire rack while you start on the next step.
Make the cake layer:
Prepare. Increase the oven temperature to 350°F.
Melt the chocolate. Melt the butter and chocolate in the microwave or a double boiler. Let the mixture cool slightly.
Mix the next four ingredients. Whisk the espresso powder, Kahlua (or coffee), salt, and vanilla in a small bowl.
Start the cake batter. Use a stand mixer fitted with the whisk attachment to beat the egg yolks with 1/2 cup of sugar, until the mixture is light in color and almost doubled in volume. Beat in the chocolate mixture, then scrape down the sides and mix on low for 5 seconds. Add the Kahlua mixture and beat until just combined. Scrape down the sides of the bowl and mix on low speed for another 5 seconds.
Whip the eggs. In a separate bowl, use the stand mixer and a clean whisk attachment to beat the egg whites until they’re foamy. Slowly increase the mixer speed to high and add the remaining sugar. Beat this mixture until soft peaks form.
Finish the cake batter. Scoop about a cup of the egg white mixture into the chocolate mixture. Gently fold in the egg whites for about 30 seconds, then add the remaining egg whites and continue folding until they are almost combined, being careful not to over-mix.
Bake. Pour the batter into the crust. Bake for 38 to 42 minutes, or until the cake is set, but jiggles slightly.
Chill. Cool the cake in the pan on a wire rack; it will deflate in the center a bit, and that’s okay! Once cooled, wrap the cake tightly and refrigerate it for at least 3 hours, or up to overnight.
Make the chocolate pudding:
Start the pudding mixture. Whisk the sugar, cocoa powder, corn starch, and salt in a medium saucepan. Add the egg yolks and whisk until the mixture resembles a thick paste. Slowly add the milk, whisking constantly as you pour.
Heat the pudding. Set the saucepan over medium heat and bring the mixture to a boil, whisking constantly so it doesn’t burn on the bottom of pan. Boil for 30 seconds, then transfer the mixture to a medium mixing bowl.
Finish the chocolate pudding. Whisk in the butter, vanilla, and chocolate for a few minutes to cool the mixture a bit.
Chill. Let the pudding stand at room temperature for 15 minutes, then press plastic wrap directly onto the surface. Refrigerate for a minimum of 3 hours.
Add the pudding layer. Stir the pudding, then pour it on top of the cake layer. Use an offset spatula to spread the pudding evenly. Return the pie to the refrigerator for at least 30 minutes.
Make the whipped cream:
Whip the cream. Add the cream to a chilled mixing bowl. Use a chilled whisk to beat the cream until soft peaks form, about 1 minute. Sprinkle the sugar over the cream, then continue whisking vigorously until stiff peaks form.
Finish the Mississippi Mud Pie. Spread the whipped cream onto the pie, all the way to the sides. Unmold and serve immediately.
What Are Soft Peaks?
Soft peaks are just that: soft and billowy. They hold their shape but collapse back into the bowl when the whisk is removed. This is in contrast to stiff peaks, which hold their shape and stand straight up when the whisk is lifted.
Tips for Success
Here’s how to make sure your Mississippi Mud Pie turns out perfect!
- Use high-quality chocolate. It’s the star of the show here, so it makes a difference! I also recommend using chocolate bars rather than chocolate chips, as they melt more smoothly.
- Don’t over-mix. Each component of this recipe, from the cake to the whipped cream, can be ruined by over-mixing.
- Clean the knife between slices. Yes, it’s a pain, but it will help keep the layers looking crisp and clearly defined. If you really want to take your slicing game to the next level, slice through the filling with a serrated knife, then use a paring knife to cut through the crust.
How to Store
Mississippi Mud Pie can be stored in the refrigerator for up to 3 days. Wrap the pie tightly with plastic wrap or place any leftovers in an airtight container.
Can This Recipe Be Frozen?
Yes, Mississippi Mud Pie can be frozen for up to 2 months. Wrap the pie tightly in plastic wrap, or place leftovers in an airtight container or freezer bag. Thaw the pie in the refrigerator before serving.
