Moist Chocolate Zucchini Cupcakes with Avocado Frosting Recipe

Delicious chocolate zucchini cupcakes that stay super moist, with reduced sugar and honey for sweetness, finished with a creamy chocolate avocado frosting.

Yes, chocolate and zucchini together—surprising, but it works beautifully. The zucchini adds moisture without a detectable vegetable taste, and the avocado frosting gives the cupcakes a rich, velvety finish. If you’re looking for a dessert that feels indulgent but uses fewer refined ingredients, these cupcakes are an excellent choice.

These cupcakes are chocolatey with just a hint of sweetness. I cut down the sugar from the original inspiration and added a touch of honey for a more balanced sweetness. The frosting, made from mashed avocado, cocoa, and honey, becomes glossy and smooth—so tempting you’ll be tempted to sample it straight from the bowl. They’re also a great way to sneak some veggies into a treat: kids usually never notice the zucchini, and they’ll happily ask for seconds.

Storage tip: because the frosting contains avocado, store the cupcakes in the refrigerator. You can also keep the frosting in a covered bowl in the fridge and top the cupcakes just before serving to preserve the freshest flavor and color.

Cooking with zucchini is a baker’s secret for moist, tender results. You won’t taste the vegetable, but it helps keep baked goods soft and satisfying. If you enjoy trying zucchini in other desserts, it’s a simple swap that transforms breads, muffins and cupcakes into something both more nutritious and delicious.

Ingredients

Instructions

1. Preheat the oven to 325°F (165°C). Line 24 muffin cups or use paper liners.
2. In a large bowl, combine the shredded zucchini, eggs, sugar, honey, Greek yogurt and vanilla. Stir until blended and set aside.
3. In a separate bowl, whisk together the whole wheat flour, unsweetened cocoa powder, baking soda, baking powder and sea salt.
4. Add the dry ingredients to the wet ingredients and mix just until combined. Avoid overmixing to keep the cupcakes tender.
5. Spoon the batter into the prepared muffin cups, filling each about three-quarters full.
6. Bake for about 25 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let cool completely on a wire rack before frosting.
7. To make the avocado frosting: in a blender or with a hand mixer, combine the mashed avocados, cocoa powder, honey (or maple syrup) and vanilla. Blend until smooth and glossy. Chill the frosting in the refrigerator until it firms slightly and the cupcakes are completely cool.
8. Frost the cooled cupcakes with the chilled avocado frosting and serve. Store leftovers in the refrigerator due to the avocado-based frosting.

Notes and Tips

• If you prefer a sweeter frosting, increase the honey or maple syrup a little at a time until it suits your taste.
• Grate the zucchini on the coarse side of a box grater; no need to squeeze out excess moisture—some of that liquid keeps the cupcakes soft.
• These cupcakes are best stored in the refrigerator because of the avocado frosting. Bring to room temperature briefly before serving if you prefer a softer texture.
• For a lighter texture, you can substitute half the whole wheat flour with all-purpose flour, but whole wheat adds a pleasant nutty flavor and extra fiber.
