These bars are pretty perfect as is, but I'd like to experiment with it in the future. Perhaps applesauce in place of the 3/4 stick of butter (it would still have a full stick!) and half the sugar. Normally I don't worry about healthifying desserts, but almost 2 sticks of butter really is a lot for such a thin dessert and the jam itself has plenty of sugar. I'll update this after I try it out! If those tweaks don't work, well, full butter and sugar it is.
Jam & Oat Bars
1 1/2 C oats (I used instant)
1 1/2 C flour
1 C brown sugar
1 tsp baking powder
1 3/4 sticks cold salted butter, cut into cubes (add 1/4 tsp salt if your butter is unsalted)
13 oz jar jam (I used Bonne Maman Cherry Preserves)
Preheat oven to 350 and grease a 9 by 13 dish. Place first 4 ingredients in bowl of stand mixer and mix until combined. Add butter and mix until everything comes together in a chunky dough. Press half of the dough into the prepared dish and spread jam on top, going almost to the edges (jam will burn a little if it touches the edges). Sprinkle remaining dough on top and press down gently. Bake until golden, about 35 minutes.
