Prepare a 9 inch baking pan by spraying it with oil and then lining it with parchment paper with an overhang so that it's easy to lift out of the baking pan after baking.
Combine the butter, all purpose flour, oats, brown sugar, baking powder and baking powder and mix until you can no longer see the flour. Add the egg and mix until fully combined.
Place about 2 1/2 cups of the oat mixture and press it into the baking pan making sure it's evenly spread. Spread the jam in an even layer on top of the oat mixture base.
Place in oven and bake for about 40-45 minutes until the top is golden brown. Remove from the oven and allow to cool to room temperature before removing from the pan.
