Yes you can. After first proofing, roll dough into a circular shape of 1/2 inch thickness. Using a doughnut cutter, cut out the shapes or use large cookie cutter or any round cutter for the circular shape and back side of the piping nozzle to cut out doughnut holes; then follow the rest of the steps to make homemade doughnuts. Only thing is in this case you won't be able to fill them with cream rather you would have to opt for sugar glaze or dip in ganache made using heavy cream and chocolate.
