Opera-in-the-Park Raspberry Bars

These are so good they should only be made once a year!

Crumb Layers:
1 1/2 cups oatmeal (old-fashioned or quick cooking)
1 cup brown sugar
1 cup butter (2 sticks) (MSPI coconut oil)
1 1/2 cups flour
1 t baking soda

Filling:
3 1/2 cups raspberries
2 T raspberry enlightenment (I used raspberry jam.)
1 1/2 cups sugar
2 T cornstarch
1/3 cup oatmeal (old-fashioned or quick cooking)
1 t. pure vanilla extract
1/2 t. cinnamon

Preheat oven to 350 degree. In a mixing bowl, combine the ingredients for the crumb layers. Mix until crumbly. Press about 2/3 of the mixture into the bottom of a greased 9 by 13 pan and set aside. From the filing, combine the ingredients in a sauce pan. Bring to a boil, stirring occasionally. Remove from the heat and let cool until only slightly warm. Spread over the bottom layer in the pan. Top with the remaining crumb mixture. Bake at 350 degrees until the topping is golden and the raspberry filling is bubbling near the center, about 40 minutes.
