belle kitchen in oklahoma city does something different i learned as i tried one of their decadent donuts made with a brioche dough. the process takes two days to make their donuts, but it results in a wonderful, tender texture that sets it apart. though it’s not just the dough that makes them so wonderful, but how it’s how they’re made. for example, their maple bacon donut has maple syrup and bacon lard mixed in the glaze, creating a rich flavor.
