Salted Egg Yolks Cookies

Recipe adapted from Cheh Cheh of Messy Witchen 

Mashed cooked salted egg yolks

Ingredients:
250g plain flour

20g cornflour
1/4 teaspoon baking powder
1/8 teaspoon bicarbonate of soda
1 tablespoon milk powder
4 salted duck egg yolks 
170g butter, softened
80g icing sugar
1/2 tsp salt

Glaze:  (Lightly beaten)
1 egg
pinch of salt

Topping:
Black & white sesame seeds

• Separate the eggs.  Steam the egg yolks until cooked.  Use a fork to mash the yolks and set aside.
• Sift together flour, cornflour, baking powder, bicarbonate of soda and milk powder. Set aside.
• Using a stand mixer cream butter and sugar until light and fluffy. 
• With the mixer on low speed, fold in sifted flours in three additions and add in mashed egg yolks.  Beat until just combined to form a dough.  Flatten the dough into a disk, wrap in cling wrap and place in the fridge for about 30 minutes.
• With the palm of your hand, gently pat the dough to flatten slightly.  Place the dough in between 2 sheets of non-stick baking paper and roll into 5mm thickness.  Use cookie cutters to cut the shape out of the dough.
• Place cookies onto a tray lined with baking paper.  Brush cookies with egg wash and sprinkle with sesame seeds.
• Bake in a preheated oven (170 deg C) for about 10 minutes or until golden brown.  
• Cool cookies completely before storing in air tight containers.
