Chocolate Revel Bars

I think these bars are best served slightly warm, although the recipe calls for them to be served after the bars have cooled. Hmm ... maybe that's my impatience.

Chocolate Revel Bars
1 stick butter, softened
2 cups brown sugar
2 large eggs
2 tsp. vanilla
2 1/2 cups flour
1 tsp. baking soda
1 tsp. salt
3 cups oats

Filling:
1 1/2 cups semi-sweet chocolate chips
14 oz. sweetened condensed milk
2 Tbsp. butter
1/2 tsp. salt
1 cup walnuts, toasted and chopped
2 tsp. vanilla

Preheat oven to 350ºF. Cover a 15 x 10 pan with foil or non-stick spray.

Cream together butter and sugar. Add eggs and vanilla. Beat until light and fluffy.

In separate bowl, combine flour, baking soda, salt and oats. Stir into creamed mixture, and set aside.

In a saucepan, combine all filling ingredients except nuts and vanilla. Heat over low until everything is melted together. Remove from heat, and stir in nuts and vanilla.

Spread 2/3 of the oatmeal batter in the bottom of the prepared pan. Cover evenly with chocolate filling. Dot with remaining oatmeal batter.

Bake 25 to 30 minutes until golden brown. Cool, and cut into squares.
