How to Make Classic Mississippi Mud Pie

Step 1: Combine crushed Oreo crumbs with melted butter and press firmly into a 9-inch pie dish.

Step 2: Whisk melted chocolate, butter, sugar, and eggs for the brownie layer, pour into the crust, and bake at 350°F (175°C) for 20 minutes. Cool completely.

Step 3: Whisk milk, sugar, cocoa powder, and cornstarch in a saucepan over medium heat until thickened into a glossy chocolate pudding.

Step 4: Spread the warm pudding smoothly over the cooled brownie layer and chill in the fridge for 3 hours to set.

Step 5: Whip heavy cream with powdered sugar until soft peaks form, then pile high over the chilled chocolate pudding.

Step 6: Garnish with dark chocolate curls or cocoa powder before slicing with a warm knife.

Raya’s Secret Tips for Success

• Chill Each Layer: Proper cooling between layers ensures clean, beautiful slices.
• Use Quality Cocoa: High-quality Dutch-process cocoa powder gives the deepest chocolate flavor.
• Warm Knife for Cutting: Wipe your chef’s knife with warm water between cuts for picture-perfect portions.

Delicious Variations

• ☕ Mocha Mud Pie: Swirl 1 teaspoon of espresso powder into the chocolate pudding layer.
• 🥜 Peanut Butter Twist: Spread a thin layer of peanut butter over the cooled brownie before adding pudding.
• 🍦 Ice Cream Style: Swap the pudding layer for coffee or vanilla ice cream for a frozen mud pie.

How to Store This Classic Mississippi Mud Pie

• Room Temperature: Not recommended due to dairy and pudding layers.
• Fridge: Store covered in the refrigerator for up to 4 days.
• Freezing: Freeze the baked crust and brownie layer for up to 2 months; assemble pudding and cream fresh.

Frequently Asked Questions

• Can I use instant chocolate pudding? Scratch-made cooked pudding sets firmer and tastes richer, but instant pudding works in a pinch!
• Why did my pie collapse when slicing? Ensure the pie chills for a full 3 to 4 hours so the pudding sets completely.
• Can I use store-bought Oreo crust? Yes! A store-bought 9-inch chocolate cookie crust saves time and works great.
