Pulse the cookies in a food processor until they are a fine texture.
Mix the cookie crumbs with the melted butter and sugar. Pat the mixture firmly on the bottom of buttered 9-inch spring-form pan. Or you can use a regular pie tin. Double the crust recipe though in order to get the crust all the way up the sides of the pie tin.
Combine all the rest of the ingredients in a bowl and stir until smooth.
Pour into the prepared spring-form pan or regular pie tin. Bake for 60 minutes, until the pie is firm in the center.
Let the pie cool for 10 minutes.
Heat caramel in microwave until it is easily pourable. Pour the caramel over the pie. Sprinkle with some flaky sea salt.
Let the pie cool till room temperature and then put it in the fridge.
