This recipe is very rich – and worth it!
1 cup plus 2 tablespoons margarine
2 cups brown sugar
4 teaspoons vanilla
3 cups oats
2-1/2 cups flour
1 teaspoon baking soda
1 (14 ounces) can sweetened condensed milk
2 cups semisweet chocolate chips
Preheat oven to 350 degrees. Cream together 1 cup margarine and the brown sugar. Beat in eggs and 2 teaspoons vanilla. Stir in the oats, flour and baking soda. Press 2/3 mixture onto the bottom of a greased 9 x 13-inch pan. In a saucepan, combine condensed milk, chocolate chips and remaining 2 tablespoons margarine. Cook, stirring constantly, over low heat until chocolate is melted. Remove from heat and stir in vanilla.
Spread over crust. Sprinkle with remaining oat mixture. Bake for 25 minutes.
