Step-by-Step Instructions

Making the Crust

The first step in preparing the Mississippi Mud Pie is to make the Oreo crust, which is a simple yet essential part of the recipe. Start by preheating your oven to 325ºF (163ºC). Once the oven is ready, place 16 Oreo cookies in the bowl of a food processor and pulse until you achieve a fine crumb consistency. If you don’t have a food processor, you can place the cookies in a resealable plastic bag and crush them with a rolling pin until the crumbs are finely ground.

Next, pour the melted butter over the crumbs and pulse the mixture until it is evenly combined. The butter will help hold the crumbs together and form a sturdy, flavorful base for your pie. Add the tablespoon of sugar to the mix and pulse a few more times until everything is well mixed.

Now, pour the crumb mixture into a 9-inch pie plate. Use your fingers or the back of a spoon to press the crumbs firmly into the bottom and up the sides of the plate. This step is important because it ensures that the crust holds its shape once baked. Bake the crust for about 15 minutes or until it becomes fragrant and slightly firm. Once baked, remove it from the oven and allow it to cool completely on a baker’s rack while you move on to the brownie layer.

Making the Brownie Layer

Once the crust has cooled, it’s time to prepare the brownie layer. In a microwave-safe bowl, combine 4 ounces of finely chopped bittersweet chocolate, 3 tablespoons of butter, 3 tablespoons of vegetable oil, and 1 1/2 tablespoons of cocoa powder. Microwave the mixture at 50% power for about 1 minute and 30 seconds, stirring every 30 seconds until the chocolate and butter are completely melted. Stir the mixture until it becomes smooth and glossy.

In a separate mixing bowl, whisk together 2/3 cup of dark brown sugar, 2 large eggs, 2 teaspoons of vanilla extract, and 1/4 teaspoon of salt. Whisk the ingredients until they’re fully combined and smooth. Once the chocolate mixture has cooled slightly, add it to the sugar and egg mixture, whisking until the two are fully incorporated.

Finally, stir in 3 tablespoons of all-purpose flour, mixing just until the flour is incorporated into the batter. Be careful not to overmix, as this could result in a dense texture for the brownie layer. Once the brownie batter is ready, pour it over the cooled Oreo crust, making sure the mixture is evenly spread across the surface.

Place the pie in the oven and bake for about 15 minutes or until the edges are set and a toothpick inserted into the center comes out with a thin coating of batter. The center of the brownie layer should still be slightly soft. Once baked, remove the pie from the oven and allow it to cool for about 60 minutes on a baker’s rack. After that, transfer it to the fridge and let it chill for at least another 60 minutes to ensure it’s completely cool and firm.

Making the Topping

While the brownie layer is chilling, it’s time to prepare the topping, which will add an extra layer of texture and flavor to the pie. Line a large rimmed baking sheet with parchment paper to prevent the topping from sticking. Take 6 more Oreo cookies and place them in a resealable plastic bag. Crush the cookies with a rolling pin until you have bits that are roughly 1/2–3/4 inch in size.

In a medium mixing bowl, combine the crushed Oreo cookies with 2 tablespoons of powdered sugar, 1 tablespoon of cocoa powder, and 1/8 teaspoon of salt. Add in 2 tablespoons of melted butter and stir until the mixture is evenly moistened and begins to clump together. This crumbly mixture will provide a delightful texture and chocolatey flavor to finish off the pie.

Spread the crumb mixture in an even layer on the prepared baking sheet, and bake for about 10 minutes or until the crumbs become fragrant and slightly crispy. Make sure to stir the mixture halfway through the baking time for even cooking. Once done, remove the baking sheet from the oven and let the topping cool completely on a wire rack. After it cools, use your hands to break up any large clumps that may have formed.

Making the Mousse

Now, it’s time to prepare the mousse layer that will crown the pie. Start by melting 6 ounces of milk chocolate in a microwave-safe bowl. Microwave the chocolate at 50% power for about 1 1/2–2 minutes, stirring every 30 seconds until the chocolate is completely melted and smooth. Once melted, set the chocolate aside to cool until it reaches a temperature of about 90º–100ºF (32º–38ºC). This is important because if the chocolate is too hot when combined with the whipped cream, it could deflate the mousse.

In a small microwave-safe bowl, heat 3 tablespoons of heavy cream in the microwave for about 15 seconds, or until it reaches a temperature of 105º–110ºF (40º–43ºC). Add 2 tablespoons of cocoa powder to the cream and whisk until fully combined. Then, add this mixture to the melted chocolate along with 2 tablespoons of powdered sugar and a pinch of salt.

In the bowl of a stand mixer, combine the remaining 1 cup of heavy cream with the chocolate and cocoa mixture. Using the whisk attachment, whip the cream on medium speed until it begins to thicken. Once it starts thickening, increase the speed to high and continue whisking until soft peaks form, which should take about 2–3 minutes. The result should be a smooth, fluffy mousse with a light texture.

Once the mousse is ready, gently fold one-third of it into the melted chocolate to lighten the mixture. After that, fold in the remaining mousse until everything is well combined. The mousse should be airy and smooth, with a velvety consistency.

Final Steps and Chilling

Once the mousse layer is ready, spread it evenly over the chilled brownie layer, ensuring that it covers the entire surface of the pie. Sprinkle the cooled Oreo crumb topping evenly over the mousse layer. Afterward, refrigerate the pie for 3–4 hours to allow the mousse to firm up. For the best results, let the pie chill overnight, allowing all the flavors to meld together beautifully.

Once chilled, slice the Mississippi Mud Pie into generous portions and serve. The layers of chocolate, from the crust to the mousse, will melt in your mouth and provide a satisfying contrast of textures.

Tips, Substitutions, and Variations

Mississippi Mud Pie offers plenty of opportunities for customization. Here are a few tips and ideas for making the pie your own:

1. For a Gluten-Free Version: If you’re looking for a gluten-free option, you can swap out the regular Oreos for gluten-free Oreos and replace the all-purpose flour with a gluten-free flour blend in the brownie layer.
2. Extra Chocolate: If you’re a true chocolate lover, add chocolate chips or chunks to the brownie layer for an extra burst of chocolate in every bite.
3. Nutty Variations: You can incorporate chopped nuts, such as walnuts or pecans, into the brownie layer or the topping for added crunch and flavor. The nuts pair beautifully with the chocolate and add another layer of texture.
4. Dairy-Free Options: For a dairy-free version, use non-dairy substitutes such as coconut oil in place of butter and coconut cream in place of heavy cream. There are also dairy-free chocolate options available that work perfectly in the mousse.
