Muffins are one of my favorite breakfast treats. I've previously shared raspberry streusel muffins, morning glory, and pumpkin muffins. These double chocolate zucchini muffins are rich, decadent, and easy to make. They're my favorite way to satisfy my chocolate cravings and use up the zucchini from my garden at the same time. Perfect for breakfast, after school snacking, or even dessert!

Why This Recipe Works: A Sprinkle of Food Science

  • Secret Ingredient: The grated zucchini releases water as it bakes which helps keep them super moist.
  • Oil Not Butter: Oil stays liquid at room temperature which helps these stay soft for days.
  • Double Leavening Baking soda works immediately while baking powder works immediately and again in the hot oven. This gives us the perfect rise every time.

Ingredient Notes and Shopping Tips

ingredients including flour, cocoa powder, oil, baking powder, baking soda, vanilla, zucchini, and chocolate chips.
  • Flour: Measure by spooning into your measuring cup and leveling with a knife. Do NOT dip the cup into the flour or you'll get too much leading to a dry dense muffin.
  • Cocoa Powder: Use unsweetened cocoa powder. I like Ghirardelli.
  • Baking Powder/Soda: Replace every 6-12 months even if the date on the package isn't expired. It loses its effectiveness over time.
  • Zucchini: No need to peel or pat it dry unless it seems very watery.
  • Oil: Vegetable oil or canola oil both work.
  • Eggs: Bring to room temperature to help them incorporate smoothly. Did you forget? Simply place in a cup of warm water for 5-10 minutes.

Krystle's Tips: Steal My Culinary School Secrets

  1. Don't Overmix: Stir until the flour streaks just disappear. Overmixing develops too much gluten and can lead to a tough end result.
  2. Don't Over Fill: I like using an ice cream scoop to fill my muffin tin. Fill only around ⅔ of the way full to give them room to rise.
  3. Don't Overbake: Bake until a toothpick inserted in the center comes out with just a few moist crumbs. If you see nothing they may overbaked, but if you see raw batter keep baking a few minutes at a time.
