Preheat the oven to 325 F (180 C). Put the flour, cornstarch, 1 cup butter, and sugar in a food processor and process until the mixture resembles coarse meal.

Place the remaining butter and brown sugar in a saucepan over low heat until melted. Add the condensed milk and bring slowly to a boil.

Melt the chocolate in double boiler and spread over the caramel. Chill in the refrigerator until set.
To serve, cut into 15 to 18 slices.
