Mastering Double Chocolate Zucchini Muffins: How-To

Creating these delicious Double Chocolate Zucchini Muffins is a breeze! Follow these simple steps to achieve muffin perfection.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your muffins bake evenly.
Step 2: Prepare the Muffin Tin
Line your muffin tin with parchment paper liners or spray it lightly with non-stick cooking spray. This will prevent your muffins from sticking.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt until well combined.
Step 4: Combine Wet Ingredients
In a separate bowl, mix the melted butter, egg, vanilla extract, and skim milk until smooth and fully incorporated.
Step 5: Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry ingredients and gently fold them together using a spatula. Be careful not to overmix; it’s okay if there are a few lumps.
Step 6: Add Zucchini and Chocolate Chips
Fold in the finely shredded zucchini and semisweet chocolate chips until evenly distributed throughout the batter.
Step 7: Fill the Muffin Tin
Scoop the batter into the prepared muffin tin, filling each cup about two-thirds full. This allows room for the muffins to rise.
Step 8: Bake
Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Step 9: Cool and Enjoy
Once baked, remove the muffins from the oven and let them cool in the tin for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy your Double Chocolate Zucchini Muffins warm or at room temperature!
Low-Carb/Keto Alternatives

If you’re looking to make these Double Chocolate Zucchini Muffins a bit healthier or lower in carbs, consider these alternatives:
- Almond Flour: Substitute all-purpose flour with almond flour for a gluten-free option.
- Stevia or Erythritol: Replace granulated and brown sugar with a low-carb sweetener like stevia or erythritol.
- Coconut Milk: Use full-fat coconut milk instead of skim milk for a creamy texture.
- Unsweetened Applesauce: Replace butter with unsweetened applesauce for a lower-fat alternative.
Behind-the-Scenes Notes
- Make sure to squeeze out excess moisture from the shredded zucchini before adding it to the batter. This helps prevent soggy muffins.
- Feel free to experiment by adding nuts, seeds, or different types of chocolate chips for variety.
- These muffins can be enjoyed warm but are also delicious when stored overnight for flavors to meld.
- For an extra indulgent treat, consider topping the muffins with a drizzle of melted chocolate or a sprinkle of sea salt.
Store, Freeze & Reheat
To keep your Double Chocolate Zucchini Muffins fresh:
- Storage: Store in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
- Freezing: Freeze muffins in a single layer on a baking sheet, then transfer to a zip-top bag for up to 3 months. Thaw at room temperature or in the microwave.
- Reheating: Reheat muffins in the microwave for about 10-15 seconds or in a preheated oven at 350°F (175°C) for 5-7 minutes.
Troubleshooting Q&A
Why are my muffins dense?
Dense muffins can result from overmixing the batter or using too much flour. Make sure to measure flour correctly and mix just until combined.
How do I know when my muffins are done?
Check for doneness by inserting a toothpick into the center of a muffin. It should come out clean or with a few moist crumbs.
Can I use frozen zucchini in this recipe?
Yes! Just make sure to thaw and drain any excess liquid from the frozen zucchini before adding it to the batter.
What can I substitute for egg in this recipe?
You can replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, let sit for 5 minutes) or ¼ cup unsweetened applesauce for a vegan option.
