Preheat oven to 190 Degrees C (375 F). Grease a 8×8 square tin and keep aside. I don’t have a square tin, so used by 8” round springform tin.

Prepare the dry ingredients by whisking together flour, powdered oats, both the sugars, baking powder, cinnamon, nutmeg and salt in a mixing bowl. Keep aside.

Stone the plums and slice them thinly. I just sliced them all around the stone and discarded it at last. I did not remove the skin as well.

Cube the cold butter and using a pastry cutter work it into the dry ingredients. I just used my finger tips to work the butter into the flour. You can also use the hand mixer.

The mixture will look like bread crumbs. Divide it 1:3 by eyeballing the mixture and transfer 3/4 of the mixture into the prepared tin.

Press the mixture firmly to the bottom either with your finger tips or by using a small flat bottomed bowl.

Arrange the plum slices all around the base and at the end give it a pat down but do not press.

Now sprinkle 2 tsp sugar evenly over the arranged plum slices and then sprinkle 1/4 of the dough mixture kept aside, covering the plum slices completely. Do not press now.

Place the tin in the Pre heated oven and bake for 35 – 40 mins.

Cool it completely in the tin itself. If you want neat slices, let it cool in the refrigerator overnight or for 8 to 10 hours.

Cut into bars or triangles as per your choice.

Serve it as a breakfast along with a glass of milk or as a dessert.
