The Ultimate Double Chocolate Zucchini Muffins (Gluten-Free)

These gluten-free, dairy-free chocolate zucchini muffins are rich, intensely chocolatey, and have an ultra-moist bakery-style crumb. By using pure cocoa powder and a generous handful of chocolate chips, they give you a double hit of chocolate that masks the hidden veggies.

Why Zucchini belongs in Chocolate Muffins

Freshly grated zucchini is a baker’s secret weapon. Because of its high water content and mild flavor, it infuses the batter with incredible moisture, allowing us to cut back on heavy fats while keeping the crumb perfectly soft.

Sweetened with unrefined coconut sugar and made with heart-healthy coconut oil, each muffin comes in at around 180 calories for a wholesome, rich treat.

• Baking Tip: Keep the skin on! There’s no need to peel the zucchini before grating, it melts  into the dark chocolate batter as it bakes, meaning no one will ever know it’s there.

Premium, Wholesome Ingredients

I’ve carefully selected clean, unrefined ingredients to ensure these muffins feel like an indulgence while staying wholesome:

• Pure Cocoa Powder: The base of our batter relies on pure cocoa, which provides that authentic, deep chocolate flavor. As a bonus, pure cocoa is naturally packed with powerful antioxidants.

• Coconut Sugar & Coconut Oil: Instead of refined sugars and heavy butter, these muffins are naturally sweetened with unrefined coconut sugar and kept moist with unrefined coconut oil.

• 180 Calories: Because the zucchini replaces a large portion of the fat, each muffin comes in at approximately only 180 calories.

Ingredient Substitutions & Dietary Tweaks

This recipe is incredibly forgiving! If you need to swap an ingredient based on what’s in your pantry, here are the swaps that work beautifully:

• The Flour: Ensure you use a high-quality “measure-for-measure” or “1-to-1” gluten-free flour blend that already contains xanthan gum. It must weight 222 grams.

• Make it Vegan (Egg-Free): Swap the two large eggs for an egg substitute.

• The Sugar: If you don’t have coconut sugar on hand, regular granulated sugar or brown sugar can be used in a 1:1 swap.

• The Oil: Both melted coconut oil and extra virgin olive oil work perfectly. If you want a slightly fruitier flavor, go with olive oil; for a more neutral flavor, use refined coconut oil. Avocado oil or melted vegan butter also work well.

• Make it Nut-Free: Swap the almond milk for any dairy-free milk of your choice, such as oat milk, coconut milk, or soy milk.

How to Store & Freeze Chocolate Zucchini Muffins

Because zucchini is so naturally hydrating, these muffins stay incredibly moist—but they need to be stored properly so they don’t get soggy!

• On the Counter: Store them in an airtight container lined with a piece of paper towel for up to 2 days. The paper towel absorbs any excess moisture.

• In the Fridge: For longer storage, keep them in the refrigerator for up to 5 days. Just pop one in the microwave for 10–15 seconds to bring back that fresh-out-of-the-oven texture.

• In the Freezer: These freeze beautifully! Wrap individual muffins tightly in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw on the counter.
