Allow bread cubes to dry out overnight, or place in a 250 degree F oven until dried.
Preheat oven to 350 degrees F.
In a medium bowl, combine sweetened condensed milk, egg substitute, butter, raisins, and cinnamon and whisk well. Add bread cubes and stir to coat. Pour mixture into a 2-quart casserole dish and bake until a knife comes out clean, about 45 minutes.
While bread pudding is baking, combine sugar substitute and cornstarch in a food processor until well combined; set aside. Remove bread pudding from heat and pour bourbon over top. Sprinkle the sugar mixture over top. Let cool slightly and then cut into pieces.
