I got it from Messywitchen but I put 4 egg yolks instead of 3 and reduced the sugar to 60 Gms
250g plain flour
20g cornflour
1/4 teaspoon baking powder
1/8 teaspoon bicarbonate of soda
1 tablespoon milk powder
3 salted egg yolks
150g butter, at room temperature
20g transfat-free shortening (or replace with butter)
1/2 teaspoon salt
80g caster sugar
1 egg mixed with 1 egg yolk, beaten lightly, for egg wash
5g each of black and white sesame seeds for topping
Method:
1. Sift together flour, cornflour, baking powder, bicarbonate of soda and milk powder, set aside.
2. Steam salted egg yolks for about 5 minutes. Cool, mash with a fork and set aside.
3. Place butter, shortening, salt and sugar in the bowl of an electric mixer. Mix on medium speed until sugar is dissolved.
4. Add mashed salted egg yolks and sifted flours. Mix to for a soft and pliable dough. If dough is too soft, wrap with cling film and rest in refrigerator for 30 minutes. (I didn’t need to chill the dough, it was just nice to roll out after mixing)
5. Line baking paper on the baking pans. Preheat oven to 170 degrees
6. Roll out dough to 5mm thickness and cut into desired shapes using dough cutters. Place on baking pans and brush with egg wash. Sprinkle with sesame seeds to decorate.
7. Bake for 20 minutes at 170 degrees or until golden brown. Remove and cool completely before storing in airtight container.
