You bet! You can change the flavor to fit your craving for the day of the week. Add a bit of pumpkin to make pumpkin donuts, and put a bit of apple juice in the donut batter for a hint of apple flavor. (just a tiny bit!) You can also add some fresh blueberries to make blueberry donuts or drizzle maple syrup on top for maple donuts. When you're making these donuts in your own kitchen, you can change the flavor of the cinnamon-sugar coating easily enough.  Adding a bit of cocoa powder can also turn them into chocolate donuts!
