Simple Raspberry Crumble Bars

0 Preheat oven to 350 degrees F. Line a 5×7 or 8×4 or similar sized baking pan with parchment paper.
1 In a food processor, process the oats until a fine flour forms. Add the rest of the ingredients except the jam and pulse until it is crumbly, like wet sand.
2 Take 3/4 of the mixture and firmly press it into the bottom of the pan. Bake for 15-20 minutes until lightly golden on the edges. Remove and let it cool (like 30 min).
3 Once it is cool to the touch, spread a layer of the raspberry jam. Add a tiny bit of water (like 1 tsp) to the leftover crumble and mix with your hands so it forms thicker clumps. Crumble the topping on top of the jam layer.
4 Bake for another 15 minutes.
5 Let it cool in the pan completely, then lift it out holding the sides of the parchment. Slice and serve!
