Ingredients You’ll Need

Every layer of this Mississippi Mud Pie relies on a handful of simple, but wildly effective ingredients. Don’t worry—each one pulls its weight when it comes to flavor and texture, making this the dessert everyone will talk about.

• Oreo Cookies (Divided, for crust and topping): The classic chocolate wafer and cream combo creates that signature crunchy base and a playful cookie topping.
• Salted Butter: Lends richness and flavor throughout the crust, brownie, and topping—plus a touch of salt to balance all the sweetness.
• Bittersweet Chocolate: The star of the brownie layer, adding a deep, dark chocolate punch that keeps things from getting too sweet.
• Vegetable Oil: Keeps the brownie extra moist and fudgy without weighing it down.
• Unsweetened and Dutch-Processed Cocoa Powder: Unsweetened cocoa adds pure chocolate depth to the brownie and whipped cream, while Dutch-processed brings a smoother intensity to the topping and mousse.
• Light Brown Sugar: Adds just a whisper of caramel flavor and keeps the brownie layer delightfully chewy.
• Eggs: Bind and set the brownie—no dense bricks here, just perfect fudgy texture.
• Vanilla Extract: Enhances the chocolate and adds a warm, inviting aroma.
• Salt: A pinch here and there makes the chocolate flavors pop.
• All-Purpose Flour: Just enough to hold the brownie layer together without getting cakey.
• Powdered Sugar: Sweetens the cookie topping and chocolate mousse, keeping both deliciously creamy.
• Milk Chocolate: The key to a luscious mousse layer that’s light yet satisfyingly rich.
• Heavy Cream: Used in both the mousse and whipped cream, it’s what gives those layers their plush, cloud-like texture.
• Granulated Sugar: Sweetens the whipped cream for the final flourish.

Variations

The beauty of Mississippi Mud Pie is in its adaptability. Whether you have dietary needs, a craving for something extra, or just love to experiment, you’ll find it’s super easy to tailor this recipe to your own tastes!

• Nutty Twist: Add a handful of toasted pecans or walnuts either in the brownie layer or sprinkled atop the mousse for extra crunch and flavor.
• Espresso Infusion: Stir a teaspoon of instant espresso powder into the brownie batter or mousse to deepen the chocolate flavor.
• Gluten-Free Option: Use gluten-free sandwich cookies and a 1:1 gluten-free flour blend for a dessert everyone can dig into.
• Peanut Butter Swirl: Swirl a dollop of peanut butter into the brownie layer before baking for a fun, family-friendly surprise.

How to Make Mississippi Mud Pie

Step 1: Make the Oreo Crust

Start by pulsing 25 Oreo cookies (cream and all) in a food processor until they’re finely ground. Mix in melted salted butter, then press the mixture firmly into the bottom and up the sides of a 9-inch springform pan. Pop it in the fridge to set while you prep the brownie layer—this helps it hold together beautifully when sliced.

Step 2: Prepare the Brownie Layer

Melt the bittersweet chocolate with more butter and vegetable oil (the trio assures that gooey, fudgy interior). Whisk in cocoa, brown sugar, eggs, vanilla, salt, and just a touch of flour until smooth and glossy. Spread the batter over the chilled crust, smoothing it to the edges. Bake until just set, with a slight wobble in the center. Let it cool while you dream of what comes next.

Step 3: Add the Cookie Topping

Pulse 8 more Oreos with powdered sugar, Dutch-processed cocoa, salt, and melted butter until coarse and crumbly. Scatter generously over the cooled brownie layer for an irresistible sweet crunch that plays perfectly with the fudgy base.

Step 4: Whip Up the Chocolate Mousse Layer

Melt milk chocolate until smooth and let it cool slightly. In a separate bowl, whip cold heavy cream with Dutch-processed cocoa, powdered sugar, and a pinch of salt until soft peaks form. Gently fold a little cream into the melted chocolate to lighten it, then fold in the rest—working carefully to keep the mousse airy. Spread this dreamy cloud over the cookie layer.

Step 5: Chocolate Whipped Cream Finale

Beat heavy cream with granulated sugar and unsweetened cocoa powder until fluffy and billowy. Dollop or pipe it in swoops over the mousse layer. Your pie now looks like a work of art and needs one last thing: several hours in the fridge to set and meld its flavors. (It’s a true test of patience, but so worth it!)

How to Serve Mississippi Mud Pie

Garnishes

This pie already looks like the belle of the ball, but if you want to dress it up: drizzle with warm chocolate sauce, scatter extra Oreo crumbs, or sprinkle with chocolate shavings just before serving. For a festive spin, a handful of toasted nuts or a cherry on top wouldn’t go amiss!

Side Dishes

Pair your Mississippi Mud Pie with something light and refreshing to complement its richness. Think fresh berries, a spoonful of tart raspberry sauce, or even a scoop of vanilla or coffee ice cream for true Southern hospitality.

Creative Ways to Present

For parties, cut the pie into slim wedges and serve on vintage plates for a nostalgic touch. Use mini springform pans to make individual servings, or layer the components into glass jars for the cutest picnic-ready desserts ever. Stacking up the layers in a tall trifle dish also makes for a dramatic presentation that never fails to impress!

Make Ahead and Storage

Storing Leftovers

Wrap any leftover Mississippi Mud Pie tightly with plastic wrap or transfer slices to an airtight container, then keep in the fridge. It’ll stay decadent for up to 4 days (if it lasts that long—midnight snacking is real!).

Freezing

You can freeze this pie for up to a month! Slice it or keep it whole; just wrap tightly and thaw overnight in the fridge before serving. The pie is delicious straight from the freezer for a firmer, ice cream–like vibe, too.

Reheating

Mississippi Mud Pie isn’t meant to be heated, but if you love a warm brownie center, you can microwave individual slices for 8-12 seconds—just enough to take the chill off and get the chocolate flavors singing.
