Preheat oven to 350F, spray a 9 inch baking dish with cooking spray.
Crush your pretzels into a crumb, I placed in a bag and crushed with a heavy glass.
Sprinkle into the bottom of your baking dish, drizzle your melted margarine on top of pretzel crumbs.
In a bowl beat together your egg, egg whites, sugar and apple sauce for 2 minutes.
Stir in your vanilla, flour, cocoa powder, baking powder and chocolate chips and mix well.
Very gently pour your brownie batter on to your pretzel crumbs, try to spread without messing up the crumbs too much, it's ok if some show through around the edges.
Pour your caramel sauce into a small zip lock bag, cut of tip of bag and drizzle on to brownie batter, top with a pinch of sea salt.
Bake in oven for 20-23 minutes.
Let cool then cut into 9 large brownies (you can cut them smaller and figure out points as they will be less)
Makes 9 brownies at 5 smart points each or 4 points plus (WW old point program)
