Mix dry ingredients: In a large bowl, combine 2 cups of plantain flour, 3 tsp xanthan gum, 1 tbsp instant yeast, and 1 tsp baking powder.
Add wet ingredients: Add 1 cup of plain unsweetened soy milk and 1 tbsp apple cider vinegar to the dry ingredients and mix.
Adjust dough consistency: If the dough is too dry, add an additional 0.5 cup of soy milk until the dough comes together and is sticky.
Handle dough: Lightly oil your hands to handle the sticky dough. Combine ingredients thoroughly without kneading extensively.
First rise: Place the dough in a bowl, cover with a clean cloth, and let it rise for 1 hour.
Shape the dough: After the first rise, roll the dough into a log shape using lightly oiled hands. Slap the dough to create a smoother surface.
Second rise: Place the shaped dough into the baking dish, cover, and let it rest again.
Add toppings: Brush the top of the dough with a little vegan yogurt and sprinkle sesame seeds on top.
Bake: Bake the loaf in a preheated oven at 180°C (356°F) for 40 minutes.
Cool and serve: Allow the bread to cool before slicing and serving.
