One of my favorite things about these muffins is they are a treat for everyone in your home. You can enjoy them just about any time of day!

For breakfast, warm them up and spread a dab of salted butter over the top. Warm muffins with melty chocolate chips are the perfect to compliment your morning cup of coffee or a tall glass of milk.

Sift a drift of powdered sugar over the top of the muffins and serve with a generous scoop of ice cream to turn these gorgeous, chocolatey muffins into a tempting dessert. 

Whether you are savoring every bite or grabbing these muffins on the go, your family will ask for them over and over again.

Ingredients

chocolate zucchini muffin ingredients
  • Butter- Adds richness and moisture, giving the muffins a tender crumb and buttery flavor.
  • Sugar- Sweetens the batter and helps create a slightly crisp top.
  • Large Eggs- Provide structure and stability, preventing the muffins from collapsing.
  • Milk-  Adds moisture and lightens the texture of the crumb.
  • Vanilla- Enhances the chocolate flavor and balances sweetness.
  • All Purpose Flour-The backbone of the muffin, providing structure.
  • Unsweetened Cocoa Powder- Creates that deep chocolate flavor. Sifting it ensures there are no lumps.
  • Baking Soda & Baking Powder-  Work together for a good rise, giving the muffins their soft, fluffy texture.
  • Salt- Balances the sweetness and sharpens all the other flavors.
  • Grated Zucchini- Adds moisture without making the batter too wet. This is the secret to tender, never-dry muffins.
  • Semi-Sweet Chocolate Chips- Melty chocolate pockets throughout every bite.

Fill, Rest, & Bake

Place cupcake liners into every other space in the muffin tins. 

Fill the cupcake liners nearly to the top of the cup cake liner.

Let the batter rest for 15 minutes.

Bake at 425 ° for 5 minutes.

Turn down the oven temperature to 350° and bake for 12-14 minutes.

FAQs

Do I need to peel the zucchini?

Nope! The peel is very thin and disappears as it bakes. Plus, it adds extra nutrients and a little extra color to the muffins.

My batter looks really thick. Is that okay?

Totally okay. This is a thick batter, but it should still be scoopable. If it feels dry, double-check that your zucchini was not over-patted (you want it damp, not bone dry).

Why do I bake at 425°F first, then lower the oven?

That quick burst of high heat helps the muffins rise tall and form a nice domed top before gently finishing at a lower temperature.

Diana's Tips for Success

Top Tip

Pat the zucchini dry. Too much water will make the muffins dense or gummy. A quick squeeze with paper towels does the trick.

  • Don't skip the batter rest! This helps the flour fully hydrate and gives the muffins a better dome when they bake
  • Only fill every other cup. Lining every other muffin space lets hot air circulate and gives each muffin room to rise tall.
  • Watch the bake time. Ovens vary in consistent temperature. It is best to start checking for doneness at 12 minutes. A toothpick should come out with a few moist crumbs, not wet batter.
