You can shred/grate your carrots by hand or in your food processor with the shredding blade. Some carrots have more moisture than others, so before you measure them, give them a gentle squeeze over your sink and allow any excess water to be removed. This helps to make a sturdy carrot cake. Scoop your shredded carrots into your measuring cup. Do not overpack or pres down otherwise you will add too much and the nutrition values for the cake will be too high.
