Add yeast and sugar to the warm milk to activate the yeast.
Let it sit for 5-7 minutes in a dry, warm place until a thick foam appears on top (white foam is an indication of active yeast)
Add oil and pumpkin puree to the milk mixture.
Stir the mixture nicely, so it's all well combined.
Mix all the dry ingredients in a separate bowl.
Fold the dry ingredients in the milk mixture. The dough should be soft and pliable but not sticky, so adjust by adding more millet flour if it is too sticky and more liquid if it is too dry.
Make a dough and lightly knead on the countertop.
Spray some cooking oil in a dish, place the dough in the dish, cover it, and let it rest in a dry and warm place.
Spray or oil the muffin pan cups.
Divide the dough into 36 pieces, shape them into balls; place three balls into each muffin pan.
Allow rising until doubled in size. Bake at 375℉ for about 25 minutes in a preheated oven.
