Oat Streusel Jam Bars

Directions

1. 1
   Add 2 1/4 cups rolled oats to a food processor. Blend until a fine flour forms. Add the brown sugar and salt and pulse to combine. Scatter the butter evenly on top and pulse until a shaggy dough just starts to form. Add the remaining oats and pulse a couple times to incorporate.
2. 2
   Remove 1 1/4 (loosely packed!) cups of streusel. Spread out the clumps (clumps are good!) on a plate and stick in the freezer to firm.
3. 3
   Meanwhile, preheat the oven to 350° F. Arrange a baking rack in the bottom third of the oven. Line a 9- by 9-inch baking pan with parchment. The easiest way to do this is cut a roughly 12- by 12-inch square. Now cut slits inward from each corner-this will help the paper fold into place. Smear a bit of butter inside the pan. Place the parchment inside and smooth out with your hands.
4. 4
   Press the remaining oat streusel into the lined pan, forming an even layer. Spread the jam on top. Take the streusel from the freezer-it should be very firm-and sprinkle on top.
5. 5
   Bake-on a rack toward the bottom of the oven-for 50 minutes, rotating halfway through. Let cool for at least 30 minutes in the pan, then use the parchment to remove from the pan, and transfer to a rack to cool completely. Cut into 16 or 12 or 9 pieces, depending on how big or little you like your jam bars.

   These freeze well. I like to wrap them individually and grab on my way out the door.
