1/2cup+ 2 TBSP whole wheat flourCan sub AP or White Whole Wheat
1cupold-fashioned rolled oats
1/4tspsalt
1/2tspbaking powder
10-12ouncesblackberry jam
Instructions
Prep: Preheat oven to 350 degrees. Spray a 8x8 baking dish with nonstick cooking spray or line with parchment paper.
Make the Bars: Melt the butter, and stir in the vanilla and sugars. Add remaining ingredients (except the jam) and stir until combined. You should have a fairly crumbly mixture. Set 1 and 1/3 cup of the mixture aside. Press the remaining mixture into the bottom of the baking dish to form your crust. Bake the bare crust for 9 minutes. Remove from the oven, and add the jam. Sprinkle the reserved crumb mixture over the top of the jam layer. You can work this mixture a bit with your hands to form some larger crumb pieces if it's super, super finely crumbled. (If the crumbs left at the bottom of the bowl are very dry, I melt an extra tablespoon of butter and add a little bit to help it come together.)
Bake: Return to the oven for about 20-25 more minutes.
Serve + Store: Let cool completely before slicing, if you want them to hold up. (You can speed this up in the fridge). If you don't care, you can cut into them sooner but they won't hold a bar shape. Store bars in an air tight container at room temperature for up to 3 days, or in the fridge for up to 5 days.
Notes
NOTE: You can easily double this recipe and bake it in two separate 8x8 pans or in one 9x13 pan.
