These Chocolate Zucchini Cupcakes are rich, super moist, and lightly sweetened with sugar and a touch of honey, then finished with a silky chocolate avocado frosting.
Yes, zucchini and avocado in chocolate cupcakes might sound unusual, but the results are fantastic. The grated zucchini disappears in the batter, yet it keeps the cupcakes incredibly tender. The avocado in the frosting adds creaminess and a glossy finish without overpowering the chocolate flavor—it’s a surprisingly perfect match.
I developed a real fondness for combining avocado and chocolate after experimenting with chocolate avocado pudding, and I wanted to bring that same creamy texture to a frosted cupcake. These turned out moist and chocolatey with just the right hint of sweetness. I reduced the sugar from traditional recipes and added a touch of honey for depth; if you prefer sweeter cupcakes, increase the sugar to taste. The frosting recipe allows honey or maple syrup, so you can choose your preferred sweetener.
Quick note about the sports-related rambling you might expect in a casual blog: life keeps going, and so do the cupcakes. If you’re following a team that lost a close game, baking these will help. They’re great to share at a game-night gathering or to cheer someone up after a rough day.
These cupcakes are excellent for families: kids rarely notice the shredded zucchini, and the avocado frosting is so creamy that a second cupcake will seem like a delightful indulgence. Because the frosting contains avocado, I recommend refrigerating the cupcakes or storing the frosting separately in a covered container and frosting just before serving.
Chocolate Zucchini Cupcakes with Avocado Frosting
Moist whole-wheat chocolate cupcakes made with shredded zucchini and lightly sweetened, topped with a smooth avocado chocolate frosting.
Prep & Bake Time
- Prep time: 15 mins
- Cook time: 25 mins
- Total time: 40 mins
- Yields: 24 cupcakes
Ingredients
- 2 cups shredded zucchini
- 3 eggs
- 1 cup sugar (increase if you prefer sweeter)
- 1/4 cup honey
- 3/4 cup plain Greek yogurt
- 2 tsp vanilla extract
- 2 cups whole wheat flour
- 2/3 cup unsweetened cocoa powder
- 1 tsp baking soda
- 1/2 tsp baking powder
- 1 tsp sea salt
For the frosting:
- 2 ripe avocados, mashed
- 1/2 cup cocoa powder
- 1/2 cup honey or maple syrup (choose based on flavor and sweetness preference)
- 1/2 tsp vanilla extract
Instructions
- Preheat the oven to 325°F (165°C) and line or grease a 24-cup muffin tin.
- In a large bowl, combine the shredded zucchini, eggs, sugar, honey, Greek yogurt, and vanilla. Mix until evenly combined and set aside.
- In a separate bowl, whisk together the whole wheat flour, cocoa powder, baking soda, baking powder, and salt.
- Fold the dry ingredients into the wet ingredients, stirring just until combined. Avoid overmixing to keep the cupcakes tender.
- Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
- Bake for about 25 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Remove from the oven and let the cupcakes cool completely on a wire rack before frosting.
- 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 fully combined. Chill the frosting in the refrigerator until it becomes firmer and spreadable.
- Frost the cooled cupcakes with the chilled avocado frosting. Keep the frosted cupcakes refrigerated and remove them from the fridge about 10–15 minutes before serving so the frosting softens slightly.
Tips and Variations
- If you prefer a milder avocado presence, use a little less avocado in the frosting or add more cocoa until you reach the desired chocolate intensity.
- For a slightly different sweetener profile in the batter, you can substitute maple syrup for the honey, adjusting liquid amounts slightly if needed.
- Use high-quality unsweetened cocoa for the best chocolate flavor. Dutch-processed cocoa will give a darker, smoother flavor while natural cocoa is brighter.
- To store: keep cupcakes refrigerated for up to 3 days. For longer storage, freeze unfrosted cupcakes and thaw before frosting and serving.
