In a bowl, combine the dry ingredients – flour, sugar, yeast, and matcha. Then add room temperature plant-based butter or margarine and plant-based milk heated to 30 degrees Celsius. Knead the dough and preferably shape it into a ball. Cover the bowl with a damp cloth and let it rest for about 30 minutes. After this time, roll out the dough on a floured surface, trying to make a thin layer. Then, spread margarine on it using a spatula. Mix sugar with cinnamon and sprinkle the dough coated with margarine with this mixture. Carefully roll the dough into a log, and then cut it into smaller buns. Place them in a deep baking tray or cake pan lined with parchment paper. Bake in an oven preheated to 160℃, using the top-bottom heating function, for 20 minutes.
