Living for Zucchini Season

I live for zucchini bread season.  Come mid-July in the midwest, fresh zucchini can be found left right and center and it’s so exciting to use it in a variety of ways.  Zucchini bread is a top way for me to use the fresh summer veggie.  I’ll eat it for breakfast, snacks, and dessert and had the “aha!” moment this summer that I should make some batches in muffin form for easy, grab and go meals.  I took my favorite zucchini bread recipe, spruced it up with some chocolate deliciousness, and batched it into a dozen perfect little muffins to make these double chocolate zucchini muffins!

This muffin recipe has been a huge hit at our house.  They are just chocolatey enough, a bit chewy from the oatmeal, and so moist from the fresh zucchini. It’s the perfect comforting, summery bite.

Frequent Recipe Questions

Can I freeze these muffins?

  • A: Yes! These muffins freeze and reheat wonderfully. Wrap and freeze the muffins in a freezer-safe zip-top bag. To warm the muffins, place one on a microwave safe dish and microwave for about 1 minute until warmed through.

Can I substitute semi-sweet chocolate chips for the dark chocolate chips?

  • A: Definitely! If you’re not a dark chocolate fan, or if you want to make this more family-friendly, you can substitute semi-sweet chocolate chips.

Tips For Making These Chocolate Zucchini Muffins

If you plan on making these double chocolate zucchini muffins, here are a few tips to be successful:

  • Mixing the wet and dry ingredients separately may seem frivolous, but it will add some insurance to creating a delicious bake.  Mixing the dry ingredients specifically, will make sure your baking powder and baking soda are evenly incorporated throughout the batter, which will create a more even rise throughout the muffin.
  • When baking with chocolate, try to purchase the highest quality you are comfortable with buying.  You can taste the difference in chocolate even more than most ingredients, making it a worthwhile area to splurge.
  • The cocoa powder can make it hard to visually tell when these muffins are baked, since it’s already brown.  To test for doneness, tap the top of the muffin with your finger to see how firm the top feels and insert a toothpick in the center. If the top feels firm and the toothpick comes out mostly clean (if it’s a little wet that’s ok, you just don’t want clumps of batter to come up with it) then you’re ready to take these muffins out of the oven!

Recipe Details

Mix the Batter

I love the simplicity of making these muffins!  All it requires is a couple bowls, a whisk, and a muffin tin. To begin, you’ll first mix all of the dry ingredients in a medium sized bowl.  Mixing these ingredients together first will make it easier to mix them into the batter at the end with all of the flavors and key baking ingredients evenly distributed.

In a separate bowl, you’ll mix the “wet” ingredients – including coconut oil, sugars, eggs, vanilla, and fresh zucchini. A great part about this recipe is that the recipe is dairy free – making it enjoyable by anyone with a dietary restriction! These ingredients will be whisked together to first incorporate a small amount of air and to get everything mixed up evenly. At this point, you can add the dry ingredients to the wet, give them a stir, and add in the chocolate chips.

Bake the Muffins

Once the batter is done, you’ll evenly divide it into a lined muffin tin and bake for about 25 minutes. Let the baked muffins cool in the tin for a few minutes and then transfer to a cooling rack to cool completely. Once cooled, you can store these muffins in an airtight container for 3 days or enjoy them immediately!  They are best eaten at room temperature or slightly warmed, either out of the oven or after microwaving for 10-15 seconds.
