Chocolate Revel Bars

I haven't made these in forever. We brought a dessert to a work gathering and I thought these would be a tasty treat to bring. I forgot how yummy and easy they are. And it makes a ton!

The recipe is from the Better Homes and Gardens cookbook.

1 cup butter or margarine
2 cups packed brown sugar
2 eggs
2 teaspoons vanilla
2-1/2 cups all-purpose flour
1 teaspoon baking soda
3 cups quick-cooking rolled oats
1 14-ounce can (1-1/4 cups) sweetened condensed milk
1 12-ounce package (2 cups) semisweet chocolate pieces
1 cup chopped walnuts
2 teaspoons vanilla

Directions

1. Set aside 2 tablespoons of the butter or margarine. In a large mixing bowl beat the remaining butter or margarine with an electric mixer on medium speed for 30 seconds. Add brown sugar; beat until well mixed. Beat in eggs and 2 teaspoons vanilla. In another large bowl stir together flour and baking soda; stir in oats. Gradually stir dry mixture into beaten mixture. Set aside.

2. In a medium saucepan combine the reserved butter or margarine, the sweetened condensed milk, and chocolate pieces. Cook over low heat until chocolate melts, stirring occasionally. Remove from heat. Stir in walnuts and the 2 teaspoons vanilla.

3. Press two-thirds (about 3-1/3 cups) of the oat mixture into the bottom of an ungreased 15x10x1-inch baking pan. Spread chocolate mixture over the oat mixture. Using your fingers, dot remaining oat mixture over the chocolate.

4. Bake in a 350 degree F oven about 25 minutes or until top is lightly browned (chocolate mixture will still look moist). Cool on a wire rack. Cut into 2x1-inch bars. Makes about 75 bars.

(I never use nuts because we don't like them. I greased my pan. I used just a Pyrex dish, I think it is the 10x13. I think that is all the alterations.)
