In a bowl. Mix bread flour, cake flour, sugar, powdered milk, baking powder, salt and instant yeast.
1 1/2 cups bread flour, 1/2 cup cake flour, 6 tbsp sugar, 1/2 tsp instant yeast, 1/2 tsp baking powder, 2 tbsp powdered milk, 1/4 tsp salt
Make a well in the center of the mixture and add vegetable shortening, and warm water. Using a spatula or wooden spoon, mix well until incorporated and turns into a rough dough.
3/4 cup warm water, 28 grams vegetable shortening
Grease work surface with vegetable shortening then place dough on top. Knead for at about 10-15 minutes until dough becomes smooth, heavy but not stretchy. Shape dough into a ball and divide in two parts.
From one part of the dough, cut a portion and weigh approx. 80 grams using a kitchen scale. Repeat the process until remaining dough is weighed then shape into smooth, small buns.
Transfer the buns into a baking tray lined with parchment paper. Cover with kitchen towel for 30 minutes to rest. NOTE: The dough will not rise since it's a dense bread. Pre-heat oven at 200°C.
To make the star bread's signature crack on top. Slit an "x" or star slice on top of the dough using a scissor or sharp knife.
Before baking, brush the top of the buns with egg wash then sprinkle sugar. Bake the bread for about 15-20 minutes or until the top is lightly browned. Remove from oven and let it cool. Bon appetit!
