What You’ll Need
- 2 medium ripe bananas (about 1 cup mashed)
- 1 cup grated zucchini (about 1 medium zucchini, squeezed dry)
- 2 large eggs
- 1/2 cup vegetable oil (or melted coconut oil)
- 1/2 cup brown sugar (light or dark, packed)
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- Optional: 1/2 cup chopped walnuts or pecans, or 1/2 cup chocolate chips
- 12-cup muffin tin
- Muffin liners or nonstick spray
- Mixing bowls, whisk, spatula, and grater
Step-by-Step
- Prepare the zucchini: Wash and dry the zucchini. Trim off the ends, then grate it using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel or several paper towels and squeeze out as much excess moisture as possible. This step is crucial to prevent soggy muffins.
- Preheat your oven: Set your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease with nonstick spray.
- Mash the bananas: In a large mixing bowl, mash the ripe bananas until smooth. You can use a fork or a potato masher.
- Mix wet ingredients: To the mashed bananas, add the eggs, oil, brown sugar, granulated sugar, and vanilla extract. Whisk until the mixture is well combined and smooth.
- Add zucchini: Fold the squeezed, grated zucchini into the wet mixture until evenly distributed.
- Combine dry ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
- Combine wet and dry mixtures: Add the dry ingredients to the wet mixture. Stir gently with a spatula until just combined. If desired, fold in nuts or chocolate chips at this stage. Do not overmix—the batter should be slightly lumpy for the best texture.
- Fill muffin cups: Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full. The batter is thick and may need to be spooned in.
- Bake: Place the muffin tin in the preheated oven and bake for 18–22 minutes. Muffins are done when the tops are golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Cool: Remove the muffins from the oven. Let them cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
- Enjoy and store: Serve warm or at room temperature. Store muffins in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. They also freeze well for up to 3 months.
Common Mistakes
- Not squeezing the zucchini dry: Skipping this step can add too much moisture, resulting in dense or soggy muffins.
- Overmixing the batter: Mixing too much after adding the flour can make the muffins tough and chewy instead of light and tender.
- Using underripe or overripe bananas: Bananas that are still green won’t provide enough sweetness or moisture. Bananas that are too far gone may contribute off flavors.
- Incorrect oven temperature: Baking at too high or low a temperature can cause uneven rising or dense centers. Always preheat your oven and use an oven thermometer if you have one.
- Filling muffin cups unevenly: This leads to uneven baking. Use a scoop or spoon to portion batter equally.
Tips
- Choose the right bananas: The best bananas for baking are heavily speckled or mostly brown. These are sweetest and easiest to mash.
- Customize with mix-ins: Add a handful of mini chocolate chips, shredded coconut, or dried fruit for extra flavor and texture.
- Make them gluten-free: Substitute a 1:1 gluten-free flour blend for the all-purpose flour for gluten-free muffins.
- For extra moisture: Add 1/4 cup unsweetened applesauce or Greek yogurt if your bananas are on the smaller side.
- Double the batch: These muffins freeze beautifully. Double the recipe and freeze extras for quick breakfasts or snacks.
- Check doneness early: Oven times can vary. Start checking your muffins at 18 minutes to avoid overbaking.
- Use parchment liners: If your muffins tend to stick, try parchment liners instead of regular paper liners for easier removal.
Troubleshooting
- Muffins are soggy or dense: This is usually due to excess moisture from the zucchini or overmixing. Next time, squeeze the zucchini more thoroughly and mix the batter gently. If it’s already baked, let the muffins cool completely—sometimes they firm up as they cool.
- Muffins stick to the liners: This can happen especially when muffins are very moist. Allow muffins to cool fully before removing liners, or use parchment liners for easy release.
- Muffins are dry or crumbly: This may be from overbaking or not enough mashed banana or oil. If the batter seemed dry, check your measurements next time and avoid overbaking.
- Unevenly baked muffins: Rotate the pan halfway through baking to ensure even heat distribution, and always preheat your oven.
- No rise or flat muffins: Check the freshness of your baking soda and baking powder. If they are old, they won’t provide enough lift.
- Muffins taste bland: Try increasing the cinnamon or vanilla, or add a pinch of nutmeg for warmth. Using very ripe bananas also helps boost flavor.
Frequently Asked Questions
- Can I use frozen zucchini?
- Yes, thaw it first and squeeze out all excess liquid before using. Frozen zucchini is often wetter, so be thorough when drying.
- How do I store zucchini banana bread muffins?
- Keep them in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. For longer storage, freeze for up to 3 months.
- Can I make these muffins vegan?
- Yes, substitute flax eggs (1 tablespoon ground flaxseed + 2.5 tablespoons water per egg) and use a plant-based oil. Check that your sugar is vegan-friendly.
- Can I use whole wheat flour instead of all-purpose?
- Yes, but the muffins will be denser. For best results, use half whole wheat and half all-purpose flour, or add an extra tablespoon of oil or applesauce.
- Why do I need to squeeze the zucchini?
- Zucchini has a high water content. Squeezing it prevents the muffin batter from becoming too wet and ensures a good texture.
- Can I add other spices?
- Absolutely! Try adding nutmeg, ginger, or allspice for more depth of flavor. Start with 1/4 teaspoon and adjust to your taste.
