What Makes Them Special

These vegan chocolate zucchini muffins hit all the right notes: rich chocolate, cake-like softness, and simple steps that even busy home cooks can handle. Here’s why I’re so convinced you’ll love them:

• No eggs or special replacers needed — just everyday ingredients like oil, dairy-free milk, and baking powder keep these muffins light and moist.
• One bowl means less mess! Whisk the wet ingredients, add dry, fold gently, and you’re good to go.
• Achieve bakery-style muffins with lofty domed tops and a soft crumb that showcase zucchini without any grassy or vegetable taste at all.
• Customizable and adaptable — toss in nuts, chocolate chunks, or espresso powder, and swap in gluten-free or whole grain flours if you like.
• Great way to use zucchini you have on hand. No need to squeeze the shredded zucchini unless it’s unusually wet.

What You’ll Need

• 2 cups (250g) shredded zucchini, coarsely grated (about 1 medium-large zucchini)
• 1 cup (200g) packed brown sugar, or granulated sugar or coconut sugar
• ¾ cup (190g) dairy-free milk of choice
• ½ cup (125g) neutral oil like light olive or vegetable oil
• 1 teaspoon vanilla extract, optional but recommended for flavor
• 2 cups (250g) all-purpose flour, spooned and leveled (see note 2 on gluten-free alternative)
• ½ cup (50g) unsweetened cocoa powder
• 3 teaspoons baking powder
• ⅛ teaspoon salt, optional but enhances flavor
• ¾ cup (130g) vegan chocolate chips, optional plus extra for sprinkling on top

Step-by-Step Method

1. Preheat oven to 180°C (350°F) and line a 12-cup muffin tin with paper liners.
2. Shred zucchini coarsely (about 2 cups from 1 medium-large zucchini); if very juicy, blot lightly with paper towels.
3. Sift cocoa powder if it’s clumpy.
4. In a large bowl combine shredded zucchini, brown sugar, dairy-free milk, oil, and vanilla; stir until zucchini shreds aren’t clumped together.
5. Add flour, sifted cocoa, baking powder, and salt to the wet mixture and gently mix just until combined.
6. Fold in vegan chocolate chips, if using, to avoid overmixing.
7. If you want taller muffin tops, either chill the batter up to 2 hours, or space muffins in the tin (leave empty cups between each) or bake only six muffins at a time.

8. Divide batter evenly into the prepared muffin pan using a spoon or ice cream scoop, filling each cup nearly full; sprinkle extra chocolate chips on top if desired.

9. Bake at 180°C (350°F) for 23–27 minutes, or until a toothpick inserted near the center comes out clean or with a few moist crumbs.
10. Optional heat-start method for taller tops: preheat oven to 220°C (425°F), bake muffins 5 minutes, then reduce temperature to 180°C (350°F) and bake about 20 more minutes until done.
11. Cool muffins in the pan for about 10 minutes, then transfer to a wire rack to cool completely.

Tips for Perfect Texture

Shredded zucchini works wonders here, and the best part? No squeezing needed! The recipe balances the extra moisture from zucchini with a bit less dairy milk so your muffins come out moist but not soggy. I like shredding zucchini in a food processor for speed, though a box grater works just fine.

If your zucchini feels extra juicy, lightly blot some moisture off with a clean towel or paper towels before mixing.

Brown sugar adds lovely depth and moistness, but if you prefer, granulated or coconut sugar works well too.

Dairy-free milk choice matters — I love soy milk for baking because its higher protein helps keep muffins tender. Oat, almond, or other plant milks work perfectly as well.

Sift your cocoa powder if it’s clumpy, so it mixes evenly throughout the batter.

Even without eggs, these muffins still rise beautifully thanks to baking powder, no special replacers needed at all.

The full ingredient list and step-by-step instructions are just below in the recipe card.

These vegan chocolate zucchini muffins bake up perfectly as is, but if you want even taller muffin tops, here’s my number one tip:

Space out the muffins in your tin, leaving empty cups between each muffin if you can (as shown below). This extra room lets hot oven air circulate better and helps muffins rise higher. If you just have one pan, bake six muffins at a time and then bake the rest in a second batch.

Another trick:

• Start baking at a higher temperature. Preheat your oven to 220°C (425°F), bake muffins for 5 minutes, then lower temperature to 180°C (350°F) for about 20 minutes to finish baking. This quick blast of heat encourages a taller rise, but lowering temp keeps muffins from drying out.
• Chill your batter for 2 hours in the fridge before baking if you have the time. It thickens the batter and can give you loftier tops. But honestly, I prefer the other faster tricks.

For the photos here, I only used the first technique with the spaced baking and the quick high-heat start.

Add-Ins and Swap Options

Wondering if you can add extras? Absolutely! Try these tasty mix-ins for a twist:

– Chopped pecans, walnuts, or almonds add crunch and flavor.
– Chocolate chunks are a fun switch-up from chips.
– Vegan white chocolate chips for a sweet surprise.
– A teaspoon of espresso powder really brings out the chocolate notes.

Different flours?

Gluten-free option: We tested King Arthur’s measure-for-measure gluten-free flour and they turn out fantastic! Just bake about 27–30 minutes for best results.

Healthier twist: Try whole wheat or spelt flour. These flours soak up more liquid, so add a splash more dairy-free milk to keep the batter moist.

Less sugar or swaps?

You can dial the sugar down to ¾ cup (about 145g) for less sweetness, though the muffins will be slightly less moist and smaller. Coconut sugar is a great swap for a milder sweetness.

I don’t recommend liquid sweeteners like maple syrup or mashed banana in a straight swap, as this needs extra tweaking. Feel free to experiment, but be prepared to test ratios.

Can I bake these in a loaf pan?

If you’re after a loaf shape, check out my chocolate zucchini bread and classic zucchini bread recipes. Loaf breads are bigger and usually need eggs or more specialized replacers for best texture.

Storage and Make-Ahead

Here’s how to keep your vegan chocolate zucchini muffins fresh, whether you want to make ahead or save leftovers:

• Room temperature: Let muffins cool completely before storing in an airtight container. They’ll keep well for up to 3 days. Place a paper towel under the muffins to help absorb any extra moisture if you’d like.
• Refrigerator: Store muffins in a sealed container for up to 5 days. Warm them briefly or bring to room temp prior to serving for the best flavor.
• Freezer (baked): Freeze cooled muffins on a baking sheet until firm, then transfer to airtight containers or freezer bags. Keep frozen for up to 1 month. Thaw at room temperature for 1–2 hours or overnight in the fridge.
• Reheating: To enjoy warm muffins from room temp or thawed, microwave for 15–25 seconds or warm in a 325°F (160–170°C) oven for 8–12 minutes. For frozen muffins, bake on a sheet at 325°F for 12–18 minutes until heated through.
• Make-ahead batter: You can rest the mixed batter in the fridge for up to 2 hours before baking to get taller muffin tops. For best rise, bake within a few hours rather than leaving overnight, since baking powder works best fresh.

Common Questions

Here are some of the most common questions I hear about vegan chocolate zucchini muffins, answered!

• Do I need to squeeze the zucchini? Nope! This recipe is made for shredded zucchini with its natural moisture intact. If your zucchini is really watery, just pat it gently with paper towels first.
• Why no eggs? Oil, dairy-free milk, and baking powder give these muffins all the rise and moisture they need. No egg replacers required to get tender, fluffy results.
• Can I reduce the sugar? Yes, you can lower it to ¾ cup (about 145g) or swap for coconut sugar. Muffins will be less sweet and slightly less moist.
• What about other flours? King Arthur’s gluten-free flour works great (just bake a bit longer), and whole wheat or spelt flour can be used with a little extra milk to keep things moist.
• How do I get tall, bakery-style muffin tops? Space muffins out in the pan, bake fewer at once, or try the heat-start method: bake at 425°F (220°C) for 5 minutes, then reduce to 350°F (180°C). Alternatively, chill batter for up to 2 hours to thicken it.
• Why are my muffins dry or dense? Overmixing, packing too much flour when measuring, or overbaking are the usual culprits. Use a scale or spoon-and-level for flour, mix gently, and watch the clock.
• Can I add mix-ins? Definitely! Nuts, chocolate chunks, vegan white chocolate chips, or espresso powder folded in gently all work beautifully.
