In a large mixing bowl, beat butter, powdered sugar until they are creamy and fluffy.
Sift the flour, baking powder, custard powder and chopped nuts in the butter mixture, along with salt. Mix them well.
Add 2 tablespoon of milk to the mixture and combine well to form a soft dough. If the dough is dry add one more tablespoon of milk.
Place the dough on a cling film and shape it into a log.
Then wrap it tightly and keep in the refrigerator for at least 2hours.
Once the dough is chilled, preheat the oven to 180°C
Line and grease the baking tray with parchment paper.
Now slice the chilled log evenly and place the cookies carefully in a baking tray and bake for 10-12 minutes or until you see the edges turning into golden colour. (Here mine done at 12 mins)
After taking the tray out from the oven, allow it to cool in the baking tray for 5mintues before transferring on to a wire rack to cool completely.
