Preheat your oven to 350°. In a bowl, sift together the flour, oats, sugar, baking powder and salt. Add the butter and vanilla stir until crumbly. Set aside 1 cup of this mixture.
Press your crumb mixture evenly into a lightly greased 13-in. x 9-in. baking pan. Spread preserves over crust.
Combine coconut and 1 cup of reserved mixture, then sprinkle over preserves.
Bake at 350° for 25-30 minutes or until coconut is lightly browned.
Notes
When we made this recipe the first time, we used strawberry preserves. It was wonderful! The second time we made it we used strawberry preserves on half, and boysenberry jam on the other half. I personally loved it, but I love boysenberry.Another note, we did use preserves, but you could use jam as well, it's all really up to what you would like.
