We just tried this recipe this past week and it was GOOD! The recipe shown here has been doubled to fit a 9x13 pan.
3 c flour
2 c old-fashioned oats
2 c packed brown sugar
1 tsp salt
1/2 tsp cinnamon
1 1/3 c cold butter
2 cans (14 oz) sweetened condensed milk
1 c lemon juice
3 tsp grated lemon peel
In a large bowl, combine the flour, oats, brown sugar, salt and cinnamon; cut in the butter until crumbly. Press 6 cups of mixture into a greased 9x13 pan; set remaining oat mixture aside. Bake at 350 degrees for 10 minutes.
In a small bowl, combine the milk, lemon juice and lemon peel. Pour over crust. Sprinkle with reserved oat mixture. Bake for 25-30 minutes or until edges are brown. Cool on a wire rack and then cut.
Have a restful and Holy Sunday. God Bless!
