In the bowl of a stand mixer, dissolve yeast and sugar in warm water until foam develops. Stir in the milk, oil, salt, baking powder and 2 cups of flour. Turn mixer on low and knead in the remaining cup of flour gradually until dough comes together and no longer sticks to the sides. Knead 5 minutes.
Cover bowl and let the dough rise for 1 hour in a warm place.
Preheat a medium sized skillet or cast iron to medium-low heat. Divide dough into 8 equal sized pieces and form into balls. Roll each ball out to a 7-inch circle.
