# How to Make It:

01 - Heat your oven to 325ºF (163ºC). Crush 16 chocolate sandwich cookies in a food processor until they're fine crumbs. Mix in 4 tablespoons melted butter until everything's wet. Push the mixture into a 9-inch pie dish. Bake it for 15 minutes till it smells good, then let it cool on a rack.
02 - Put 4 ounces dark chocolate, 3 tablespoons butter, 3 tablespoons cooking oil, and 1 1/2 tablespoons cocoa in a microwave-safe container. Heat at half power, stirring now and then, until it's all melted (about 90 seconds). In another bowl, mix 2/3 cup dark brown sugar, 2 eggs, 2 teaspoons vanilla, and 1/4 teaspoon salt. Add the chocolate mix to the wet stuff, then gently stir in 3 tablespoons plain flour. Pour over the cooled crust and bake for 15 minutes until the sides look set. Cool an hour on a rack, then chill another hour in the fridge.
03 - Warm oven to 325ºF (163ºC). Cover a cookie sheet with baking paper. Break 6 chocolate sandwich cookies into small chunks. Mix 2 tablespoons icing sugar, 1 tablespoon cocoa, 1/8 teaspoon salt, and 2 tablespoons melted butter with the broken cookies. Spread it on the cookie sheet and bake 10 minutes, giving it a stir halfway, until it's crunchy and smells good. Cool it down on a rack.
04 - Melt 6 ounces milk chocolate in a microwave-safe bowl at half power, stirring often, until smooth (about 1.5-2 minutes). Warm 3 tablespoons cream in the microwave for 15 seconds till it's 105º-110ºF and mix with 2 tablespoons cocoa. Add 2 tablespoons icing sugar, a tiny bit of salt, and the rest of the cream (1 cup minus 3 tablespoons). Beat in a mixer until soft peaks show up (around 2-3 minutes). Mix 1/3 of the whipped cream into the melted chocolate. Then carefully fold in what's left of the cream. Spread this mousse on top of the cold brownie layer.
05 - Sprinkle the cookie crumb mix on top of the pie. Put it in the fridge for 3-4 hours or leave it there overnight before you serve it.

# Additional Tips:

01 - Make sure the brownie's totally cool before you add the mousse or it'll mess up the texture.
02 - Use a cooking thermometer to get the temps right when making your mousse.
03 - This sweet treat tastes even better if you make it a day ahead.
