Ingredients You’ll Need
Don’t let the impressive layers fool you—each ingredient in Mississippi Mud Pie plays a key role in creating its irresistible taste and texture. From rich chocolate to crunchy cookies, here’s how each element shines.
- Oreo cookies (25 for crust, 8 for topping): The chocolatey cookie base and crunchy topping are classic, and using Oreos ensures a satisfyingly deep flavor in every bite.
- Salted butter (6 Tbsp + 3 Tbsp + 2 Tbsp, melted): Adds just the right balance of richness, binding together the crust and topping for that perfect crisp-meets-chewy texture.
- Bittersweet chocolate (4 ounces, chopped): Deepens the cocoa notes in the brownie layer—choose your favorite high-quality chocolate!
- Vegetable oil (3 Tbsp): Keeps the brownie super moist and fudgy.
- Unsweetened cocoa powder (2 Tbsp + 1 Tbsp + 2 Tbsp + 3 Tbsp): Intensifies chocolate flavor in every layer, so don’t skimp on these chocolatey spoonfuls.
- Light brown sugar (2/3 cup): Lends the brownie layer warmth and chewiness.
- Large eggs (2): Essential for binding the brownie and providing structure.
- Vanilla extract (2 tsp): This tiny splash brings a subtle, wonderful depth to the pie.
- Salt (1/4 tsp + pinches): A little salt wakes up all the flavors.
- All-purpose flour (3 Tbsp): Just enough to set the brownie without losing any gooey fudginess.
- Powdered sugar (2 Tbsp + 2 Tbsp): Used in the cookie topping and mousse layer for smooth sweetness.
- Dutch-processed cocoa powder (1 Tbsp + 2 Tbsp): Boosts the chocolate color and flavor in the topping and mousse.
- Milk chocolate (6 ounces, chopped): Makes the mousse layer extra light and creamy—use a chocolate bar you love to snack on.
- Heavy cream (1 cup cold + 1 cup): Transforms into both the mousse and a luscious pillow of whipped cream.
- Granulated sugar (1/4 cup): Adds a touch of sweetness to whipped cream for delicious contrast.
How to Make Mississippi Mud Pie
Step 1: Make the Oreo Crust
Start by preheating your oven to 325°F. Crush 25 Oreo cookies into fine crumbs using either a food processor or, for some old-school fun, a rolling pin and a sturdy ziplock bag. Drizzle over melted salted butter and stir until every crumb is beautifully coated. Press this mixture firmly and evenly into a 9-inch pie plate, making sure to go up the sides. Bake the crust for 12-15 minutes, until set, then let it cool just a bit while you tackle the dreamy layers.
Step 2: Prepare the Fudgy Brownie Layer
Combine the bittersweet chocolate, more melted butter, vegetable oil, and unsweetened cocoa powder in a microwave-safe bowl. Heat in 20-second bursts, stirring each time, until everything has melted together like a chocolate symphony. Whisk in the brown sugar, eggs, vanilla, and salt, then gently stir in the flour. Pour this luscious brownie batter over your cooled crust and smooth it out. Bake for around 25-30 minutes—don’t overbake! You want a toothpick to emerge with just a whisper of moist batter, or a thermometer to register about 180°F. The goal is maximum goo. Let this layer cool completely.
Step 3: Make the Crunchy Cookie Topping
To add some drama to your Mississippi Mud Pie, grab 8 Oreo cookies and bash them into rough chunky crumbs. Toss with powdered sugar, Dutch-processed cocoa, a pinch of salt, and melted butter until everything is gloriously chocolaty and moist. Spread this mixture onto a parchment-lined baking sheet and bake for 10 minutes until crisp. Cool completely before sprinkling on the finished pie for an epic textural moment.
Step 4: Whip Up the Chocolate Mousse Layer
Melt chopped milk chocolate gently in the microwave, using 20-second intervals and stirring well so nothing scorches. Let it cool until it’s about body temperature—cool to the touch but still fluid, about 10 minutes. Meanwhile, beat cold heavy cream with Dutch-processed cocoa powder, powdered sugar, and salt until you get soft peaks. Gently stir a third of this chocolate whipped cream into your cooled chocolate, then fold in the rest for a mousse so airy you’ll want to eat it by the spoonful. Spread this cloud-like filling over the cooled brownie layer. Chill the pie for at least 3 hours (overnight is even better) for perfectly defined layers.
Step 5: Top with Chocolate Whipped Cream and Cookie Crunch
Whip together heavy cream, granulated sugar, and unsweetened cocoa powder until gorgeous stiff peaks form. Spread generously over your luxurious mousse layer. Finally, scatter your homemade chocolate cookie crunch over the top. Stand back and admire your masterpiece—it’s officially time to indulge in Mississippi Mud Pie perfection!
How to Serve Mississippi Mud Pie
Garnishes
This pie is a knockout as is, but a few extra flourishes make it even more irresistible. Sprinkle chocolate shavings or mini chocolate chips over the whipped cream for bonus glam, add a drizzle of warm fudge sauce, or dust it all with cocoa powder or a sprinkle of flaky salt. Each touch enhances the layers already packed into every slice.
Side Dishes
While Mississippi Mud Pie will happily steal the show, you can pair it with some simple sides for a winning dessert spread. Try a big scoop of vanilla ice cream for a hot-and-cold flavor play, or fresh berries to cut through the chocolatey richness. Even an icy glass of milk or strong cup of coffee makes the moment feel extra indulgent.
Creative Ways to Present
If you’re serving a crowd or want to impress for a special event, get creative! Cut the pie into dainty squares for a finger-friendly dessert platter, serve in jars for personal parfaits, or use mini tart pans for adorable individual Mississippi Mud Pie bites. A drizzle of chocolate sauce in a contrasting zigzag makes every slice look bakery-worthy.
Make Ahead and Storage
Storing Leftovers
Mississippi Mud Pie keeps beautifully, making it an ideal make-ahead dessert. Cover the pie loosely with plastic wrap or foil and refrigerate for up to 4 days. The layers stay distinct, and the flavors have even more time to meld for deep, fudgy deliciousness.
Freezing
If you need to prep well in advance, Mississippi Mud Pie freezes like a dream! Wrap tightly with plastic and foil, or place the whole pie in a freezer-safe container. Freeze for up to a month, then thaw overnight in the fridge before serving. For best texture, add the whipped cream and cookie crunch after thawing.
Reheating
This pie is meant to be served cold or at room temperature, so there’s no need for reheating. If you prefer the brownie layer a little warmer (and extra gooey), you can microwave individual slices for 10-15 seconds—just don’t overdo it or you’ll melt the mousse and cream!
FAQs
Can I use different cookies for the crust and topping?
Absolutely! While classic Oreos are iconic, you can swap in any crisp chocolate cookie you love. Chocolate graham crackers or gluten-free chocolate cookies both work beautifully, and give the Mississippi Mud Pie a subtle twist.
What’s the best way to cut clean slices?
For the neatest slices, use a sharp knife dipped in hot water and wiped dry before each cut. This helps you glide through each layer without smudging the gorgeous mousse or whipped cream.
Can I make this pie in advance?
Yes, in fact Mississippi Mud Pie is even better when made a day ahead! The flavors mingle, the layers set up perfectly, and the whole dessert is stress-free when it’s time to serve.
How do I prevent the brownie layer from overbaking?
Check your brownie at the minimum bake time, and look for a toothpick to come out with a little moist batter (not totally clean). If you’re unsure, an instant-read thermometer reading around 180°F ensures gooey results without raw batter.
Can I make Mississippi Mud Pie gluten free?
Yes! Just use gluten-free chocolate sandwich cookies for the crust and topping, and substitute a 1:1 gluten-free flour blend in the brownie layer. The result is just as decadent and crowd-pleasing.
Final Thoughts
With its glorious layers and showstopping flavor, Mississippi Mud Pie always brings the “wow” factor to any table. I can’t recommend it enough for your next celebration, chocolate craving, or family get-together. Don’t be surprised if it quickly becomes your own most-requested dessert—now, go ahead and treat yourself to a slice of pure Southern bliss!
