Don’t let the zucchini fool you — this isn’t health food pretending to be dessert.
This Chocolate Zucchini Cake is a deeply chocolatey, moist, and tender treat that just happens to have a vegetable in it. The zucchini adds incredible moisture and a soft crumb — with zero veggie taste.
Think of it as a cross between a decadent chocolate cake and a spiced coffee cake — perfect for brunch, dessert, or a midday slice with a cup of coffee.
Better yet? It’s easy to make, one-bowl friendly, and loved by kids and adults alike.

🔥 Instructions
1. Preheat & Prep
- Preheat oven to 350°F (175°C).
- Grease and flour a 9-inch round cake pan, 8×8-inch square pan, or line a loaf pan with parchment paper.
2. Grate & Dry the Zucchini
- Grate zucchini using a box grater.
- Place in a clean kitchen towel and squeeze out as much liquid as possible.
✅ This is key — wet zucchini = soggy cake.
3. Mix Dry Ingredients
- In a medium bowl, whisk together:
- Flour
- Cocoa powder
- Baking soda
- Baking powder
- Salt
- Cinnamon (if using)
4. Combine Wet Ingredients
- In a large bowl, whisk together:
- Oil (or melted butter)
- Granulated and brown sugars
- Eggs
- Vanilla extract
- Mix until smooth and slightly fluffy (about 1–2 minutes).
5. Combine Wet & Dry Mixtures
- Gradually add the dry ingredients to the wet, mixing just until combined.
- Stir in the buttermilk until smooth.
6. Fold in Zucchini (and Add-Ins)
- Gently fold in the squeezed zucchini.
- Add chocolate chips and/or nuts, if using.
7. Bake
- Pour batter into prepared pan.
- Bake for:
- 25–30 minutes for round/square pan
- 50–60 minutes for loaf pan
Until a toothpick inserted in the center comes out clean or with moist crumbs.
8. Cool & Serve
- Let cool in the pan for 10 minutes, then transfer to a wire rack.
- Serve warm or at room temperature.
