Introduction

Mississippi Mud Pie is a rich and indulgent dessert that combines a chocolate cookie crust, a fudgy chocolate layer, and a creamy chocolate mousse topping. Finished with fluffy whipped cream and optional chocolate decorations, it’s a decadent treat perfect for chocolate lovers.

A round pie with three visible layers sits in a white pie dish on a white marbled surface. The bottom layer is dark and crumbly, like a chocolate cookie crust. Above it is a smooth, thick middle layer of milk chocolate, creamy and even. The top layer is a thick, fluffy white cream spread evenly with light brown cocoa powder sprinkled on top. Part of the pie is missing, showing the clean cuts between the layers. In the background, there are blurred items like glass bottles and a white cloth. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

24 chocolate sandwich cookies (like Oreos)
6 tablespoons unsalted butter, melted
1 cup semi-sweet chocolate chips (for fudge layer)
½ cup heavy cream (for fudge layer)
½ cup granulated sugar
2 large eggs
2 teaspoons vanilla extract (divided)
1 cup semi-sweet chocolate chips (for mousse layer)
1½ cups heavy cream, divided (for mousse and whipped topping)
2 tablespoons powdered sugar (for mousse layer)
3 tablespoons powdered sugar (for whipped cream topping)
1 teaspoon vanilla extract (for whipped cream topping)
Optional decorations: chocolate shavings, curls, sticks or pieces, cocoa powder

Instructions

Step 1: Preheat your oven to 350°F (175°C). Crush the chocolate sandwich cookies in a food processor until fine crumbs form. Add the melted butter and pulse until the mixture resembles wet sand. Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish, compacting tightly with the bottom of a glass or measuring cup. Bake for 8-10 minutes, then let cool completely.
Step 2: In a heatproof bowl, melt 1 cup chocolate chips and ½ cup heavy cream together over a double boiler or in the microwave in 20-second increments, stirring until smooth. In a separate bowl, whisk together granulated sugar and eggs until combined. Slowly pour the melted chocolate mixture into the egg mixture while whisking constantly. Stir in 1 teaspoon vanilla extract. Pour over the cooled crust and bake at 325°F (163°C) for 15-18 minutes, until edges are set but center is slightly wobbly. Cool completely.
Step 3: Melt 1 cup chocolate chips with ½ cup heavy cream, stirring until smooth. Let cool slightly. Whip the remaining 1 cup heavy cream with 2 tablespoons powdered sugar until stiff peaks form. Gently fold whipped cream into the cooled chocolate mixture. Spread mousse evenly over cooled fudge layer. Chill in the refrigerator for at least 3 hours, until set.
Step 4: Whip 1½ cups heavy cream with 3 tablespoons powdered sugar and 1 teaspoon vanilla extract until stiff peaks form. Spoon or pipe whipped cream over the chocolate mousse layer. Use a piping bag fitted with a star tip for a decorative finish if desired.
Step 5: Decorate the top with chocolate shavings, curls, sticks, or pieces. Lightly dust with cocoa powder for a polished look, if you like.

Tips & Variations

Use high-quality chocolate for a deeper, richer flavor in the fudge and mousse layers.
For a nutty twist, sprinkle chopped toasted pecans or walnuts in the crust before baking.
Chill the pie overnight for the best texture and flavor melding.
Try adding a splash of coffee or espresso powder to the melting chocolate for enhanced chocolate depth.

Storage

Store Mississippi Mud Pie covered in the refrigerator for up to 3 days. For longer storage, freeze the pie wrapped tightly in plastic wrap and aluminum foil for up to 1 month. Thaw in the refrigerator overnight before serving. Rewhip the topping if needed after thawing.

FAQs

Can I make Mississippi Mud Pie ahead of time?

Yes, this pie benefits from chilling before serving. You can prepare it a day or two in advance and keep it refrigerated to allow flavors to meld and layers to set properly.

Can I use a pre-made crust instead of the cookie crust?

While the cookie crust is traditional and adds great texture, you can substitute with a store-bought chocolate or graham cracker crust if you prefer a quicker option.

Instructions

Make the Crust: Preheat your oven to 350°F (175°C). Crush the chocolate sandwich cookies in a food processor until fine crumbs form. Add the melted butter and pulse until the mixture resembles wet sand. Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish, using the bottom of a glass or measuring cup to compact it tightly. Bake for 8-10 minutes, then let it cool completely.
Prepare the Fudge Layer: In a heatproof bowl, melt the chocolate chips and heavy cream together over a double boiler or in the microwave in 20-second increments, stirring until smooth. In a separate bowl, whisk together the sugar and eggs until well combined. Slowly pour the melted chocolate mixture into the egg mixture, whisking constantly. Stir in the vanilla extract. Pour the fudge mixture over the cooled crust and bake at 325°F (163°C) for 15-18 minutes, until the edges are set but the center is slightly wobbly. Cool completely.
Make the Chocolate Mousse Layer: Melt the chocolate chips with ½ cup of heavy cream in the microwave or over a double boiler, stirring until smooth. Let it cool slightly. Whip the remaining 1 cup of heavy cream with the powdered sugar until stiff peaks form. Gently fold the whipped cream into the cooled chocolate mixture. Spread the mousse evenly over the cooled fudge layer. Chill in the refrigerator for at least 3 hours, or until set.
Whipped Cream Topping: Whip the heavy cream, powdered sugar, and vanilla extract together until stiff peaks form. Spoon or pipe the whipped cream over the chocolate mousse layer. For a decorative finish, use a piping bag fitted with a star tip.
Add the Finishing Touches: Decorate the top with chocolate shavings, curls, or pieces. Lightly dust the top with cocoa powder, if desired, for a polished look.

Notes

Be sure to cool the crust completely before adding the fudge layer to prevent sogginess.
The fudge layer should have slightly wobbly center when done baking to achieve the perfect texture.
Use a gentle folding technique to keep the mousse light and airy.
Optional chocolate decorations add a beautiful finish but are not necessary for great flavor.
Allow refrigeration time to fully set the mousse layer for best slicing results.
