Chocolate Marble Zucchini Bread

The other day my dad brought me a zucchini from his garden and I knew I wanted to make a zucchini bread with it.

I love the addition of chocolate and chocolate chips so this bread was born.

I made it late at night and didn’t even taste it until the next day, which is rare for me. I never have the willpower to hold off. But, once I decided it was delicious, I cut it up to take pictures.

My new house has a ton of windows, which I thought would be great for picture taking, but I was wrong. So wrong. I can’t get a decent picture anywhere in the house (believe me, I’ve tried every room), so I’ve been taking all my pictures on the back deck (see it here and here).

Anyway, all that to say that this bread is really good and I managed to get these pictures in about 3 minutes with 12 interruptions to save Julia’s life.

Equipment you’ll need

  • A loaf pan – I have both glass loaf pans and dark non-stick loaf pans. I really don’t prefer one over the other – they both get the same end result!
  • A box grater – I have a mini grater and a larger box grater. I like using the larger one for zucchini because it works really quick.
  • GOOD cinnamon – so cinnamon isn’t really a tool but buy a good quality ceylon cinnamon. It lasts a long time and makes a big difference in your baked goods. Some of those cheap ones at the grocery store are tempting but they have fillers and just don’t taste good!

Do you grate the whole zucchini for zucchini bread?

Yes, you grate the entire zucchini when you’re making zucchini bread. Peel & all! Makes it super easy.

How many zucchini do you need for 1.5 cups of shredded?

This zucchini bread recipe calls for 1.5 cups of shredded zucchini. Depending on the size of your zucchini (sometimes those garden zucchini are HUGE), you’ll likely need 1-2 medium zucchinis to get 1.5 cups of shredded zucchini.
