200 g powdered sugar –> yes, you can use icing sugar
1/2 teaspoon vanilla extract –> this is important, do not omit!
Preparation
Mix together all the dry ingredients except for the salt. Add 200 ml water (reserve the rest for adjustment) and egg yolks.
Blend together and knead until the dough forms a ball. Add butter and salt, knead until the dough does not stick to the bowl anymore and becomes elastic.
Roll the dough long, cut into 20-30 g pieces, roll each dough into a ball. Cover with plastic, let them rise twice their initial volume (about 1-2 hour).
Brush the surface with a runny mixture of egg and milk, bake at 180 degree celsius until done.
Cut the bun in half, let it stale overnight. The next morning, turn on your oven at160-170 degree celsius, spread it with Butter Spread, bake until crisp.
Butter Spread: Mix all ingredients together until fluffy.
