SALTED EGG YOLK COOKIES

Ingredients:
(Recipe adapted from here). I halved the recipe.
250gm plain flour ( 135gm plain flour )
20gm corn flour ( 15gm corn flour )
1/4tsp baking powder ( 1/8tsp baking powder )
1/8tsp baking soda (half)
4 cooked salted egg yolks , mashed ( i used 4 egg yolks )
170gm butter, softened ( 95gm unsaled butter )
80gm sugar ( 40gm )
black and white sesame seeds ( optional )
1/2 tsp milk powder (1/4 tsp ) - I added this
1/2 tsp salt (1/4 tsp sat) - I added this

glaze : 1 egg yolk

note: add more flour if the dough is too wet until pliable.

Method:
1. Sift together plain flour, corn flour, baking powder and baking soda and set aside.
2. Using an electric mixer, beat butter, sugar and salt till sugar is dissolved.
3. Add in the mashed salted egg yolks and sifted flour, mix to a soft pliable dough (mine is not pliable, soft but manageable). If dough is too soft, wrap in cling film and keep in the refrigerator for 30 mins.
4. Line baking tray with baking paper and preheat oven to 170C
5. You can divide the dough into 2 and then keep one dough in the fridge while you are working on the other dough. Place the dough between 2 plastic sheets and roll out dough to 5mm thickness ( i rolled mine to 2-3mm as it will expand a little bit during baking ) and cut them using your desired cookie cutter. Apply glaze , sprinkle some sesame seeds and bake for about 15-20 mins ( The dough is quite soft and i have used a small spatula to lift them up to the baking tray and i baked mine for 16 mins.)
