Preparing Fresh Zucchini:

Fresh zucchini is best when making this chocolate quick bread. I love to have fresh picked zucchini or bought from the store. Either way, this zucchini bread is always a hit!

  • Summer or Fall Season: This bread is best made with the freshest zucchini vegetable. If possible, use a home grown zucchini rather than a store bought zucchini. Zucchini is best picked from the garden in the summer or fall season.
  • Grating Zucchini: Cut the ends off the zucchini and do not peel if you would prefer. Use a grater to grate with the skin on or off. Fresh zucchini is very moist and watery. This will increase the breads moistness as it bakes as well.
  • Drain Moisture: Place the grated zucchini in a sieve or several paper towels. Discard any excess liquid from the zucchini the best that you can. Let it sit while combining ingredients.
  • Dry Zucchini: Add some water to the zucchini to help moisten the zucchini before adding it to the bread batter.

Variations and Substitutions:

Create your perfect bread using these variations and substitutions. Enjoy chocolate zucchini bread just the way you like it!

  • Add Water: If you notice your zucchini is not moist. Either add 1 to 2 Tablespoons to the bread batter or soak the shredded zucchini for a few minutes before adding it to the bread batter.
  • Flour: White flour is best. If you are wanting a whole wheat flour use half and half flour.
  • Cocoa: Make sure to use natural unsweetened cocoa powder to help activate the baking soda. Do not use dutch process cocoa for this chocolate bread.
  • Sugar: Add a little more sugar (¾ cup) to make a sweeter bread.
  • Yogurt: Substitute sour cream for a low fat plain greek yogurt. Vanilla flavor will also work or non greek yogurt.
  • Chocolate Chips: Add in peanut butter chips or white chocolate chips for a variation. Chocolate chips are a must for this bread to become sweater and more flavorful.
  • Slicing Bread: Let the bread cool before slicing the bread. It is best to slice the chocolate zucchini bread with a bread knife. Slice zucchini bread with a bread knife.
