double chocolate zucchini muffins – Gluten Free

Chocolate zucchini muffins make a wonderful healthy breakfast treat that feels like a little indulgence! These muffins are packed with shredded zucchini, almond flour, and plenty of chocolate, resulting in a moist, fudgy texture that everyone in the family will love — especially the kids!

My family went crazy for these Chocolate Zucchini Muffins, and I was thrilled about it! They’re naturally gluten free and healthier because we’re sneaking in some veggies, but don’t worry — the chocolate flavor totally steals the show.

Plus, who says chocolate can’t be a part of breakfast? Especially alongside a nice hot mug of coffee. Once zucchini starts spilling out of your garden or farmer’s market in late summer, this double chocolate zucchini muffins recipe becomes an absolute lifesaver.

I swear shredded zucchini should be a secret ingredient in all baked goodies. It adds amazing moisture and a subtle texture without overpowering flavor — much like in my favorite Zucchini Banana Bread or Zucchini Cake. No one even guesses there’s a veggie hidden in there!

Even better, zucchini’s mild taste blends right in, making these treats a clever way to sneak some extra greens into your family’s diet.

• Loaded with good fats and nutrients from almond flour and almond butter.
• Rich chocolate flavor that’s indulgent, yet healthy.
• Kid-approved and mom-approved — a rare combo!
• Double chocolate means double the yum.

What You’ll Need

• 1 + ¼ cup blanched almond flour
• ⅓ cup cocoa powder – unsweetened
• 1 teaspoon baking soda
• ½ teaspoon kosher salt
• 1 large egg – lightly whisked
• ⅓ cup maple syrup
• ¼ cup unsweetened applesauce
• ¼ cup creamy almond butter
• ¼ cup non-dairy milk – like almond or coconut milk
• 1 tablespoon olive oil or coconut oil
• 1 teaspoon vanilla extract
• 1 cup shredded zucchini – with the extra water squeezed out
• ⅔ cup chocolate chips – plus more for topping

Step-by-Step Method

1. Preheat oven to 400°F and line a 12-cup muffin pan with liners.
2. Shred the zucchini finely with a box grater.
3. Wrap the shredded zucchini in a clean kitchen towel and wring tightly to squeeze out excess water.
4. Whisk together the dry ingredients: almond flour, cocoa powder, baking soda, and salt.
5. Whisk together the wet ingredients: egg, maple syrup, applesauce, almond butter, non-dairy milk, olive oil, and vanilla until smooth.
6. Stir the dry ingredients into the wet ingredients until a thick, chocolatey batter forms.

7. Gently fold the squeezed shredded zucchini and chocolate chips into the batter until evenly distributed.

   

8. Use a spoon or ice cream scoop to divide the batter evenly among the 12 muffin liners without overfilling.
9. Bake 22–25 minutes in the preheated oven, until a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
10. Remove muffins from the oven and cool 15–20 minutes before removing liners and serving.

Pro Tips for Success

These gluten free double chocolate zucchini muffins usually take about 25 minutes in my oven, but ovens can differ quite a bit, so start checking around 22 minutes. Keep in mind, some zucchini muffin recipes (like these Fluffy whole wheat carrot zucchini muffins) might take longer, depending on ingredients and moisture.

Zucchini is a brilliant addition to baked goods because its flavor is very mild. It blends effortlessly into batters, making treats super moist, soft, and tender without any leftover veggie taste.

• Shred the zucchini finely for the best texture. I find a box grater works great because it has a finer side that basically makes the zucchini disappear in the muffin.
• Always follow your specific recipe’s guidance on squeezing out zucchini water (see the technique in these Crispy and Easy Zucchini Fritters) — some recipes want it dry, others rely on the extra moisture for structure. It’s part of the baking science, and the difference really counts!

Note: For this double chocolate zucchini muffins recipe, definitely squeeze out the excess water to keep your muffins from getting wet and heavy.

• Shred the zucchini finely and squeeze the moisture out well. This simple step makes a big difference, giving you the perfect crumb in your muffins.
• Stir the batter thoroughly to spread the zucchini evenly so every bite is just right.
• Don’t overfill the muffin liners — use an ice cream scoop to portion the batter evenly for the best rise and even baking.
• Start checking your muffins at 22 minutes. A toothpick should come out with some moist crumbs but no wet batter. If it’s not clean yet, bake a few more minutes.
• Cool the muffins before eating. Give them 15 to 20 minutes so the liners peel off easily and the texture firms up perfectly for that fudgy bite.

Notes

• Shred and squeeze the zucchini well with a clean kitchen towel to get the perfect texture and avoid soggy muffins.
• Mix the batter thoroughly so zucchini pieces spread evenly for consistent flavor.
• Don’t overfill muffin liners — use an ice cream scoop to get even-sized muffins that bake uniformly.
• Test muffins at about 22 minutes with a toothpick. A few moist crumbs are perfect, but no wet batter.
• Cool muffins for 15-20 minutes before removing liners or serving — this helps the texture set beautifully.
• Storage: Store these muffins in an airtight container at room temperature for up to 3 days or freeze for up to 1 month. Defrost overnight before enjoying.

Mix-Ins and Substitutions

Want to mix things up? Here are some easy swaps and extras to personalize your double chocolate zucchini muffins without changing your method (and if you’ve got extra zucchini on hand, try easy garlic parmesan roasted zucchini):

• Flour swaps: Instead of almond flour, try a 1:1 gluten-free blend or regular all-purpose flour if gluten isn’t a concern. Coconut flour can work but expect a drier and denser muffin that might need more liquid or eggs.
• Nut-free option: Swap out almond butter for sunflower seed butter and use seed milk to make nut-free muffins.
• Sweetener swaps: Use honey in place of maple syrup (same amount) or dial back sweetness if you prefer.
• Milk: Any unsweetened milk works — almond, oat, or even dairy milk.
• Flavor boosters: Toss in chopped nuts like walnuts or pecans, a teaspoon of espresso powder to deepen the chocolate, some orange or mint zest, or a pinch of cinnamon.
• Chocolate variations: Go semi-sweet, dark, or even white chocolate chips. Sprinkle extra chips or flaky sea salt on top before baking for added flavor contrast.
• Size changes: Make mini muffins by reducing baking time or jumbo muffins by increasing it — just watch with a toothpick test for doneness.

Storage and Make-Ahead Tips

Here’s how to store and reheat your double chocolate zucchini muffins to keep them fresh and tasty:

• Room temperature: Store cooled muffins in an airtight container on the counter for up to 3 days.
• Refrigerator: To keep them longer, refrigerate in an airtight container for a few extra days — this helps slow down staling.
• Freezing: Freeze cooled muffins for up to a month. Freeze them first on a baking sheet until firm, then transfer to a freezer bag to avoid crushing. This method also works well for our Chocolate Banana Protein Muffins (one bowl) if you’re stocking the freezer with a few varieties.
• Thawing: Defrost muffins overnight in the fridge or at room temperature for a couple of hours before enjoying.
• Reheating: Warm muffins in the microwave for 10-20 seconds or heat in a 300-325°F oven for 8-12 minutes until heated through and slightly crisp on top.
• Make-ahead tip: Mix dry ingredients and store in a sealed container for quick baking later. Because baking soda reacts with liquids, bake soon after mixing the wet and dry ingredients for best results. For a high-protein make-ahead option, try High-Protein Blueberry Cottage Cheese Muffins.
