Prepare Bakers Truth™ Spice Cake Donut Mix according to bag directions. Grate carrots and zucchini, then place them into a cheesecloth and wring out the excess moisture. Add grated vegetables to the donut batter in the last minute of mixing.
Fry at 375°F for 1 minute on each side.
Finish by rolling donuts in cinnamon sugar mixture while still warm.
