Chocolate Caramel Bars

I got this recipe from the Taste of Home Cookbook and everyone loves it. How can anything go wrong with chocolate and caramel.

1 C. flour
1/2 C. brown sugar
1/2 C. butter
2 C. coarsely chopped pecans
1 C. flaked coconut
14 oz. sweetened condensed milk
2 tsp. vanilla
20 vanilla caramels
2 tbs. milk
1 C. chocolate chips

Crust:
Stir together flour and brown sugar. Cut in butter with a pastry blender. Press into a greased 9X13 pan. Bake at 350 degrees for 15 minutes. Sprinkle pecans and coconut over hot crust.

Filling:
Combine sweetened condensed milk and vanilla; pour over pecans and coconut. Bake 25-30 minutes. Cool 10 minutes. Meanwhile, in saucepan, mix caramels and milk. Cook and stir over med. heat just till melted (I use the microwave). Drizzle over the top and sprinkle with chocolate chips. Cool and cut. Yum!
