In the bowl of an electric mixer, beat eggs, sugar, vanilla and salt on medium speed until well combined. Add melted chocolate mixture and flour, mix on low speed just until combined.
Stir in chocolate chips and 1/2 cup of the chopped Skor bar. Pour into prepared pan and spread evenly. Sprinkle remaining candy bar on top and gently press in. Bake for 25 to 30 minutes or until a toothpick inserted comes out with just a few moist crumbs. Don't overbake!
