Ingredients for Chocolate Zucchini Cupcakes
Here’s what you’ll need to whip up these wonderfully moist chocolate treats. Don’t worry if you don’t have chocolate chips; they’re totally optional but add an extra layer of deliciousness. The zucchini is key here, folks – it’s what makes these cupcakes so unbelievably tender and moist, almost like a secret ingredient in a Mexican street corn inspired deviled eggs recipe!
- 1 ½ cups (190 g) all-purpose flour – the base for our tender cupcakes
- ½ cup (60 g) unsweetened cocoa powder – for that deep, rich chocolate flavor
- 1 tsp baking powder – helps them rise beautifully
- ½ tsp baking soda – works with the cocoa for lift
- ½ tsp salt – balances the sweetness
- 1 cup (200 g) granulated sugar – for sweetness and moisture
- ½ cup (120 ml) vegetable oil – keeps them super moist
- 2 large eggs – bind everything together
- 1 tsp vanilla extract – enhances all the flavors
- 1 ½ cups (180 g) grated zucchini (about 1 medium, unpeeled) – the star for moisture!
- ½ cup (120 ml) milk or buttermilk – adds extra tenderness and moisture
- ½ cup (90 g) chocolate chips (optional) – for little bursts of chocolate goodness
How to Make Chocolate Zucchini Cupcakes
Whipping up these moist chocolate treats is surprisingly simple, and the results are incredibly rewarding. Get ready for some deliciousness!
- Step 1: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners. This ensures your cupcakes bake evenly and don’t stick.
- Step 2: Grate your zucchini. I like to use the medium side of a box grater. Lightly blot the grated zucchini with a paper towel to remove just enough excess moisture so they don’t make the batter too wet.
- Step 3: In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. This dry mix forms the base of our cupcakes.
- Step 4: In a separate, larger bowl, whisk together the granulated sugar, vegetable oil, large eggs, and vanilla extract until everything is smooth and well combined. You want a nice, emulsified base.
- Step 5: Stir the grated zucchini and the milk or buttermilk into the wet ingredients until just combined. It might look a little thick, but don’t worry!
- Step 6: Gradually add the dry ingredients to the wet mixture, mixing in two batches. Stir just until the flour streaks disappear. Overmixing can make your cupcakes tough, and nobody wants that! Fold in the chocolate chips now if you’re using them. They’re like little surprises, similar to how you might find a burst of flavor in elote deviled eggs.
- Step 7: Divide the batter evenly among the prepared cupcake liners, filling each about ⅔ full. This gives them room to rise without overflowing.
- Step 8: Bake for 18–20 minutes. You’ll know they’re done when a toothpick inserted into the center of a cupcake comes out clean, with just a few moist crumbs attached. The aroma filling your kitchen will be heavenly!

- Step 9: Let the cupcakes cool in the muffin tin for about 5 minutes before carefully transferring them to a wire rack to cool completely. This step is crucial to prevent them from breaking.
- Step 10: If you’re making the frosting, beat the softened butter until creamy. Gradually add the powdered sugar, unsweetened cocoa powder, milk, and vanilla extract, beating until light and fluffy. Frost when the cupcakes are totally cool.
Pro Tips for the Best Chocolate Zucchini Cupcakes
I’ve baked these more times than I can count, and I’ve picked up a few tricks to make them absolutely perfect every time. Follow these tips, and you’ll have moist, rich chocolate cupcakes that are sure to impress!
- Don’t overmix the batter: This is crucial! Mix just until the dry ingredients are incorporated. Overmixing develops the gluten too much, leading to tough cupcakes.
- Grate, don’t shred: Use the medium holes on your grater for the zucchini. Shredding too finely can release too much moisture, while grating too coarsely might leave noticeable bits.
- Let them cool completely: This is a big one, especially if you plan to frost them. Warm cupcakes will melt the frosting and can fall apart. Patience is key!
- Fold in chocolate chips gently: If you’re adding chocolate chips, fold them in at the very end. This prevents them from breaking down too much and staining the batter.

What’s the secret to perfect Chocolate Zucchini Cupcakes?
The true secret is the grated zucchini! It adds incredible moisture and tenderness without any discernible zucchini flavor. It acts much like the corn in elote deviled eggs, adding a unique texture and moisture.
Can I make Chocolate Zucchini Cupcakes ahead of time?
Yes, absolutely! You can bake them a day in advance and store them in an airtight container at room temperature. If frosting, wait until they are completely cool, then frost them just before serving for the best texture.
How do I avoid common mistakes with Chocolate Zucchini Cupcakes?
The most common pitfalls are overmixing the batter, which results in dense cupcakes, and frosting them while they’re still warm, which leads to a melty mess. Also, ensure you’re not squeezing all the moisture out of the zucchini!
Best Ways to Serve Chocolate Zucchini Cupcakes
These rich chocolate zucchini cupcakes are so decadent, they’re perfect on their own, but I love to dress them up a bit! For a truly indulgent dessert experience, try serving them with a scoop of vanilla bean ice cream. The cool, creamy vanilla is a beautiful contrast to the warm chocolate flavor. Another idea is to pair them with a fresh raspberry coulis; the tartness cuts through the richness wonderfully, much like a spicy kick complements the creaminess in chipotle elote deviled eggs. They also make for a delightful afternoon treat with a hot cup of coffee or a glass of cold milk.

How to Store and Reheat Chocolate Zucchini Cupcakes
Keeping these wonderfully moist chocolate zucchini cupcakes fresh is a breeze, whether you’re planning for leftovers or making them ahead. Once they’ve cooled completely on the wire rack, it’s time to think about storage. For the best results, especially if they’re frosted, I recommend an airtight container. This prevents them from drying out and keeps them tasting as fresh as possible. Store them at room temperature for up to 3-4 days. They’re pretty forgiving and maintain their delicious texture!
If you find yourself with an abundance of these delightful treats, freezing is a fantastic option. Wrap each unfrosted cupcake tightly in plastic wrap, then in a layer of aluminum foil. This double-layer protection is key to preventing freezer burn. You can freeze them for up to 3 months. When you’re ready to enjoy them, simply transfer the frozen cupcakes to the refrigerator overnight to thaw. For a gentle reheat, you can warm them briefly in a 300°F (150°C) oven for about 5-10 minutes until just warmed through. This method is perfect for recapturing that just-baked freshness, making them almost as good as the day you made them, much like how properly stored elote deviled eggs remain a crowd-pleaser.
Variations of Chocolate Zucchini Cupcakes You Can Try
While this recipe is already fantastic, I love experimenting with variations to keep things exciting! Whether you have dietary needs or just want to mix up the flavor profile, there are so many delicious ways to enjoy these chocolate zucchini cupcakes. They’re as versatile as a base recipe for elote deviled eggs, offering endless possibilities!
- Gluten-Free Option: Simply swap out the all-purpose flour for a good quality gluten-free baking blend. Make sure the blend contains xanthan gum for structure. The zucchini will keep them delightfully moist!
- Vegan Delight: For a vegan version, replace the eggs with a flax egg (1 tbsp flaxseed meal + 3 tbsp water, let sit for 5 minutes) and use your favorite plant-based milk, like almond or soy milk. You can also skip the optional frosting or use a vegan buttercream.
- Mocha Magic: Amp up the chocolate flavor by adding 1-2 teaspoons of instant espresso powder to the dry ingredients. This creates a wonderful mocha flavor that pairs beautifully with the rich chocolate, much like how chipotle enhances the corn in elote deviled eggs.
- Spiced Chocolate: Introduce a hint of warmth by adding a pinch of cinnamon or a dash of nutmeg to the batter. This subtle spice note adds another layer of complexity to the chocolate flavor.
