In a small bowl, mix the yeast, coconut sugar, and hot water. Stir gently and let it sit at room temperature for 5 minutes to wake up the yeast and form a thick foam on top.
In a large bowl, mix the flours, salt, soy milk, coconut oil, coconut sugar, and the yeast mixture. Once it comes together, knead with your hands for 10-15 minutes until the dough is smooth and elastic. In the same large bowl, cover the dough and put in a warm place to rise for about 1 hour, or until doubled.
After the dough has risen, rub some vegan butter or coconut oil around a 9×13 pan to grease it, then cut the dough into 12 equal parts. Roll each part into smooth balls and place in pan. Cover again and rise in a warm place for 45 minutes.
Pour ⅔ of the glaze over the risen buns, then bake for 30 mins at 350F.
When the buns are nice and golden, remove them from the oven and pour the rest of the sauce over them. Enjoy while they are still warm from the oven!
