Place cookie crumbs in a large bowl and pour the butter over top. Stir until the crumbs are uniformly saturated.
Spoon 2 teaspoons of the mixture into 6 ramekins. Using the back of a spoon, press the cookies into the base of the ramekin creating an even, flat surface. Chill while you make the ganache.
For the Ganache
Place chocolate chips in a medium-sized, non-reactive bowl and set aside.
Pour the heavy cream in a saucepan and place over medium heat. Whisk in the corn syrup and cook until steam begins to form on the surface of the cream.
Pour the cream mixture over the chocolate and let sit for 10 minutes. Stir the mixture until all the chocolate melts. The ganache should look smooth and glossy.
Leave the ganache to sit at room temperature for an hour. Once the hour has passed, scoop 1 tablespoon of ganache into each of the ramekins. Place the ramekins in the fridge to chill while you make the creme brûlée.
For the Creme Brûlée
Preheat the oven to 325° F.
Pour heavy cream into a saucepan and place over medium heat. Heat the cream until steam begins to form on the surface. Remove the pan from the heat and stir in the vanilla. Cover the pan and let the cream steep for 15 minutes.
Place the egg yolks in a medium-sized bowl. Add the sugar and the salt and whisk until uniform.
Once the cream is finished steeping, pour two ladles-full of the cream mixture into the egg mixture. Whisk vigorously to temper the eggs.
Add the now tempered eggs into the rest of the cream mixture and stir until uniform. Transfer the mixture to a container with a spout.
To Assemble
Place the chilled ramekins in a large casserole dish and put a full kettle on to boil.
Fill the ramekins with the creme brûlée mixture up to the top. Take care not to pour the mixture directly onto the ganche.
Once the kettle boils, pour boiling water into the casserole dish until it reaches halfway up the sides of the ramekins.
Place the casserole dish in the oven and bake for 40-45 minutes or until the edges of the creme brûlée are set while the centers remain jiggly. Transfer the ramekins to the fridge and chill for at least 2 hours.
Dust the surface of the chilled creme brûlées with 1 teaspoon of sugar each. Using a kitchen torch, brûlée the surface in an even, sweeping motion until deep amber in color. Let cool for 15 minutes.
