In your breadmaker pan or stand mixer bowl, add the water or milk, cooking oil, sugar, vanilla essence if using, and yeast.
Add the flours, making sure to cover the surface of the liquid completely.
Add the salt and baking powder.
Start the machine, using the Dough program.
Once the knead cycle ends, let rest for about 15 minutes.
If not using a breadmaker, using your stand mixer mix and knead at the lowest speed on your mixer until a shaggy dough forms, then increase the speed one step and continue kneading, about 14 to 15 minutes. Shape into a round ball and let rest in your mixing bowl, placed in a warm place and covered with a damp cloth, 15 minutes.
Transfer the dough to a floured surface.
Divide the dough to your desired size. I usually divide my dough into 16 pieces for filled buns. Each piece should weigh around 55 to 57 grams.
Use as required.
