Put 1 1/2 cups of flour in the bowl of the stand mixer (or regular bowl if you aren’t using a mixer) making a small well (you will be pouring your wet ingredients into it).
Put 3/4 cup of coconut milk, 1/4 cup of the sugar and the water in a medium sized pot. Turn the stove to medium heat and heat this mixture, while stirring, until it is warm but not hot. Remove the milk mixture from heat and stir in the yeast.
Pour the milk/yeast mixture into the flour well. Put a tea towel over the bowl and let it sit for 20 minutes.
Add the oil. Turn on the mixer to medium speed (with a dough hook) and begin to mix. Or if doing this by hand begin to lightly knead. Once the ingredients are well incorporated slowly start to work in the remaining flour. Continue to knead, adding flour until the dough is no longer sticky.
Cover again with the tea towel and let rise for 30 minutes (your dough will double in size).
Form the dough into buns, place in a well greased cast iron pan or baking dish, cover and let rise once more for 30 minutes.
