These addictively delicious Cast Iron Yeast Rolls are soft with a golden, buttery top, and baked in a cast iron skillet.
Heat the 1/2 cup of milk to 100-110 degrees. Mix with packet of yeast and let sit for ten minutes.
In base of a mixer fit with dough attachment, mix together buttermilk, flour, salt, sugar, 1/4 cup of softened butter, and egg. Once well mixed, stir in the yeast/milk mixture. Continue mixing until a ball of dough forms.
Spray a bowl with cooking spray and place dough in bowl, then flip dough so that both sides of dough are covered with spray. Cover bowl with a clean dish towel or plastic wrap. Let sit in a warm place, without a draft, and rise until doubled in size, about 75-90 minutes.
