In a small nonstick pot on the stove, combine sugar, cornstarch, cinnamon, and salt with 2 tablespoons of cold water. Stir to dissolve. Add apples and lemon juice and stir. Bring to medium heat and cover. Cook until the apples have softened and liquid has thickened, about 5 minutes, uncovering often to stir.
Remove the pot from heat and transfer the mixture to a bowl. Allow it to cool for several minutes. Thoroughly stir in cream cheese. Fold in whipped topping.
Lay crepes flat on a dry surface. Evenly distribute the apple mixture between the crepes. Fold each crepe up envelope-style, first folding the sides in, and then folding/rolling it up from the bottom.
Bring a skillet sprayed with nonstick spray to medium heat. Place the crepes in the skillet with the seam-sides down. Cook them until slightly browned, about 1 minute per side. (Flip carefully.)
Plate your crepes and drizzle them with caramel dip. If you like, sprinkle with powdered sugar. Try not to pass out as you dig in!
