Combine powdered sugar, corn starch and butter and mix thoroughly with a wooden spoon or a silicone spatula till it becomes light and creamy.
Sift the flour with baking powder and salt.
Add the cinnamon and nutmeg powder into the flour mixture and mix well.
Add the flour mixture into the beaten mixture of sugar and butter and knead well till it forms a dough. If the dough is too crumbly add one or two tablespoons more of butter and knead. Care should be taken not to over knead. Excess kneading will make the cookies hard.
Cover with cling film and leave it to rest for 20 minutes.
Knead it lightly once more and make into smooth lime-sized balls and place them on a buttered or parchment lined cookie sheets. Leave some space in between the balls of dough as they get bigger on baking.
Place the cookie sheets in the preheated oven for 18 – 22 minutes depending your oven. After 15 minutes keep a close watch on them and remove them from the when they are still slightly soft in the middle.
Leave it on the sheet for another 5 minutes before transferring to a cooling rack.
