3/4 cup packed brown sugar
3/4 cup rolled oats
1 and 1/2 cups all purpose flour (I used half whole wheat)
1/2 teaspoon soda
3/8 tsp salt
10 tablespoons cold butter, divided
3 small apples, cored, unpeeled and thinly sliced
2 teaspoons lemon juice, divided
1/2 tsp cinnamon
1/2 cup sugar
1 and 1/2 tablespoons cornstarch
1/2 cup hot water
1/2 teaspoon vanilla extract
1/2 cup chopped pecans, optional
Directions:
Preheat oven to 350 degrees. Line a nine inch square pan with foil. In a large bowl, combine brown sugar, oats, flour, soda, and salt. Cut in 9 tablespoons butter. (This can also be done in a food processor.) Reserve 3/4 cup and pat the rest into prepared pan. It will be dry. Toss apples with half of lemon juice and arrange over crust in pan. Sprinkle with cinnamon. In a saucepan, combine sugar, cornstarch and hot water. Turn heat to medium and cook, whisking constantly until mixture begins to boil and thicken. Remove from heat and stir in vanilla, remaining 1 tablespoon butter and remaining teaspoon of lemon juice. Pour over apples. Sprinkle with remaining crumb mixture and pecans, if using. Bake at 350 degrees for 35-45 minutes, or until lightly browned.
