Preheat the oven to 350 degrees. Butter a 9 x 13 or 8 x 10 baking dish.

Mix together the flour, oats, brown sugar, baking powder, cinnamon and salt in a food processor. Cut up butter and place in food processor. Pulse until crumbly. Sprinkle half the mixture into the pan and pat lightly to pack it a little tight. Spoon preserves evenly over the surface, spread. Sprinkle the other half of the oat mixture over the top and pat lightly again.

Bake until light golden brown on top, about 30 to 40 minutes. Remove from the oven and let cool in pan.

When cool, cut into squares and serve. Yum!
