Revel Bars (Yummy Yummy Yummy)

From our good friend, Julene Williams, Blackfoot, Idaho

1 cup butter
2 cups packed brown sugar
2 eggs
2 tsp vanilla
2 ½ cups flour
1 teaspoon baking soda
3 cups quick rolled oats (I use just a little less)
1 14 oz can of sweetened condensed milk (1 ¼ cups)
1 12 oz package semi sweet chocolate chips
1 cup chopped walnuts
1 teaspoon vanilla

Set aside 2 tablespoons of butter. In a large mixing bowl beat the remaining butter for 30 seconds, add brown sugar and beat in eggs and vanilla. In another mixing bowl stir together flour, baking soda and rolled oats. Stir dry mixture into beaten mixture. Press dough into a large baking pan. (I use the large cookie sheet) In a medium saucepan combine the 2 tablespoons butter, chocolate chips, and sweetened condensed milk, melt over low heat. After chips are melted remove from heat, stir in walnuts and 2 tsp vanilla and spread over dough. Bake in 350 oven for 25 minutes or until top is lightly browned. (I usually cook a little less or they are dry) Maybe check your altitude and make adjustment.
