Prepare Donut Mix according to bag directions, then roll out and cut into rings, saving the ring centers. Alternatively, roll out and cut with a donut hole cutter. Fry and let cool completely.
For Lemon Ricotta Filling, combine 1oz Lemon Icing Fruit Bits, 3oz powdered sugar, and 1 pound ricotta cheese. Fill donut holes with prepared filling and dust with donut sugar.
