Notes

  • Don't feel the need to peel the zucchini before shredding! You can shred the zucchini as is. No need to peel it!
  • Don't over mix the batter! Once you combine the wet and dry ingredients, make sure you don't over mix. This can result in a tough and dense zucchini cake!
  • To store, place your zucchini bars in an airtight container in the refrigerator for up to 5 days.
  • To make these into muffins or cupcakes, follow my zucchini bread muffins recipe!
