Prep Time, Cook Time, and Servings

Prep Time: 30 minutes | Cook Time: 45 minutes | Total Time: 4 hours 15 minutes (including chilling) | Servings: 8

Ingredients

For the Oreo Crust:

• 25 Oreo cookies
• 6 Tablespoons salted butter, melted

For the Brownie Layer:

• 4 ounces bittersweet chocolate, chopped
• 3 Tablespoons salted butter, melted
• 3 Tablespoons vegetable oil
• 2 Tablespoons unsweetened cocoa powder
• 2/3 cup light brown sugar
• 2 large eggs
• 2 teaspoons vanilla extract
• 1/4 teaspoon salt
• 3 Tablespoons all-purpose flour

For the Toasted Cookie Topping:

• 8 Oreo cookies
• 2 Tablespoons powdered sugar
• 1 Tablespoon Dutch-processed cocoa powder
• Pinch of salt
• 2 Tablespoons salted butter, melted

For the Chocolate Mousse:

• 6 ounces milk chocolate, chopped
• 1 cup cold heavy cream
• 2 Tablespoons Dutch-processed cocoa powder
• 2 Tablespoons powdered sugar
• Pinch of salt

For the Whipped Cream Topping:

• 1 cup heavy cream
• 1/4 cup granulated sugar
• 3 Tablespoons unsweetened cocoa powder

Instructions

1. Prepare the Oreo Crust

First, preheat your oven to 325°F. Crush the Oreo cookies into fine crumbs using a food processor or a heavy-duty ziplock bag and rolling pin. Mix the crumbs with melted butter until they resemble damp soil. Press the mixture firmly into a 9-inch pie plate and bake for 12-15 minutes until set. Let it cool.

2. Make the Fudgy Brownie Layer

In a microwave-safe bowl, melt bittersweet chocolate, butter, oil, and cocoa powder in 20-second increments, stirring each time until smooth. Add brown sugar, eggs, vanilla, and salt, whisking until combined. Gently stir in flour. Pour the batter into the cooled crust and bake for 25-30 minutes. A toothpick should come out with moist crumbs, and an instant thermometer should read 180°F.

3. Create the Toasted Cookie Topping

Crush the 8 Oreos into chunky pieces and toss them with powdered sugar, cocoa powder, and salt. Drizzle with melted butter, then spread on a parchment-lined baking sheet. Bake for 10 minutes and let cool.

4. Whip Up the Chocolate Mousse

Melt milk chocolate as before, then let it cool to 90-100°F. Whip cold heavy cream with cocoa powder, powdered sugar, and salt until soft peaks form. Fold one-third into the cooled chocolate to lighten, then gently mix in the rest.

5. Assemble and Chill

Spread the mousse over the brownie layer and refrigerate for at least 3 hours. Before serving, whip the final heavy cream with sugar and cocoa until stiff, then spread it over the pie. Top with the toasted cookie pieces.

Pro Tips for Perfect Results

1. Use a food processor for fine Oreo crumbs, ensuring an even crust.
2. For the fudgiest brownie, pull it out when the thermometer reads 180°F.
3. Fold the mousse gently to maintain its airy texture.
4. Chill the pie overnight for the best consistency.
5. Toast the cookie topping just until fragrant to avoid burning.

Variations and Substitutions

Try gluten-free Oreos and a gluten-free flour blend for a gluten-free version. Substitute dark chocolate for milk chocolate in the mousse for a richer taste. For a lighter option, use whipped coconut cream instead of heavy cream in the topping.

Storage and Reheating Tips

Store the pie in the refrigerator for up to 4 days, covered. The mousse may soften slightly, but it will still taste delicious. Do not freeze, as the texture may change.

FAQ

Can I use regular cocoa powder instead of Dutch-processed?

Yes, but Dutch-processed has a smoother flavor. Adjust by adding a pinch more sugar if using natural cocoa.

Can I make this ahead of time?

Absolutely! Assemble up to a day in advance, but add the whipped cream and topping just before serving.

What if I don’t have a food processor?

A blender or a ziplock bag with a rolling pin works fine for crushing Oreos.

Can I skip the mousse layer?

Yes, but it adds a luxurious texture. Simply top the brownie with whipped cream and cookie pieces.
