Caramel Candy Bars

This was my favorite dessert/bar my grandma made. Beware, they are addicting...and not that good for you, of course :o)

1 package (14 oz) caramel candies
1/3 cup milk
2 cups flour
2 cups oats
1 1/2 cups packed brown sugar
1 tsp. baking soda
1/2 tsp. salt
1 egg
1 cup softened butter or margarine
1 package (6 oz) semi-sweet chocolate chips
1 cup chopped walnuts or dry roasted peanuts

Heat oven to 350 degrees. Grease 13x9x2 in. pan. Heat candies and milk in 2-quart saucepan over low heat, stirring frequently, until smooth. Remove from heat. Mix flour, oats, brown sugar, baking soda, salt, and egg in large bowl. Stir in margarine with fork until mixture is crumbly. Press half of mixture into pan. Bake 10 minutes. Sprinkle with chocolate chips and walnuts; drizzle with caramel mixture. Sprinkle remaining crumbly mixture over top. Bake until golden brown, 20-25 minutes. Cool 30 minutes. Loosen edges from sides of pan. Cool completely.
