Chocolate Revel Bars

Step 1
Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking pan.

Step 2
In a large bowl, beat together 1 cup butter and brown sugar until fluffy. Mix in eggs and 2 teaspoons vanilla. In another bowl, combine oats, flour, baking soda, and 1 teaspoon salt; stir into butter mixture. Set aside.

Step 3
In a medium saucepan, heat sweetened condensed milk, chocolate chips, 2 tablespoons butter, and 1/2 teaspoon salt over low heat, stirring until smooth. Remove from heat. Stir in walnuts and 2 teaspoons vanilla.

Step 4
Pat 2/3 of the oat mixture into the bottom of the prepared pan. Spread chocolate mixture evenly over the top, and dot with remaining oat mixture.

Step 5
Bake for 30 to 35 minutes in preheated oven. Let cool on a wire rack, then cut into bars.
