What You’ll Need
- 2 medium ripe bananas (about 1 cup mashed)
- 1 medium zucchini (about 1 cup grated)
- 2 large eggs
- 1/2 cup vegetable oil (or melted coconut oil)
- 1/2 cup brown sugar (packed)
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour (can substitute half with whole wheat flour)
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- Optional: 1/2 cup chopped walnuts or chocolate chips
- Muffin tin and liners or nonstick spray
- Mixing bowls, whisk, spatula, box grater
Step-by-Step
- 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.
- Prepare the zucchini. Wash and dry the zucchini. Trim off the ends and grate it using the coarse side of a box grater. Place the grated zucchini in a clean kitchen towel and squeeze out excess moisture over the sink. Set aside.
- Mash the bananas. In a large mixing bowl, mash the ripe bananas with a fork until mostly smooth, with just a few small lumps.
- Mix wet ingredients. Add the eggs, oil, brown sugar, granulated sugar, and vanilla extract to the mashed bananas. Whisk until fully combined and smooth.
- Add the zucchini. Stir the squeezed, grated zucchini into the banana mixture until evenly distributed.
- Combine dry ingredients. In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt. If using whole wheat flour, replace up to half of the all-purpose flour for extra fiber.
- Combine wet and dry ingredients. Add the dry ingredients to the wet mixture. Stir gently with a spatula or wooden spoon until just combined. Avoid overmixing; a few streaks of flour are okay. If desired, fold in nuts or chocolate chips.
- Portion the batter. Divide the batter evenly among the muffin cups, filling each about 3/4 full.
- Bake. Place the muffin tin in the oven and bake for 18–22 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
- Cool. Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving. Enjoy warm or at room temperature!
Common Mistakes
- Not squeezing out the zucchini: Excess water in zucchini can make muffins soggy and dense. Always squeeze out as much liquid as possible before adding it to the batter.
- Overmixing the batter: Overworking the batter develops gluten, leading to tough, chewy muffins instead of light and tender ones. Stir just until the flour disappears.
- Using underripe bananas: Bananas that are not fully ripe lack sweetness and flavor, which can make muffins bland. Use bananas with plenty of brown spots for the best results.
- Overbaking: Muffins baked too long will dry out quickly. Start checking for doneness at the lower end of the time range and remove them as soon as a toothpick comes out clean.
- Filling muffin cups unevenly: This can cause some muffins to overbake while others are undercooked. Use a cookie scoop or measuring cup for even portions.
Tips
- Customize with add-ins: Stir in up to 1/2 cup of chopped nuts (walnuts or pecans), chocolate chips, or dried fruit for extra flavor and texture.
- Make them healthier: Substitute half the flour with whole wheat, use coconut oil or applesauce instead of some of the oil, or reduce the sugar slightly if desired.
- Double the batch: These muffins freeze well. Make a double batch and freeze extras for quick breakfasts or snacks. Wrap cooled muffins tightly and store in a freezer bag for up to 3 months.
- Use muffin liners: Liners make for easy cleanup and prevent sticking, especially if you use less oil in the recipe.
- Test for doneness: Insert a toothpick into the center of a muffin. If it comes out clean or with just a crumb or two, they’re done. If it’s wet, bake for a few more minutes.
- Let them cool: Muffins continue to set as they cool, so let them cool in the pan for a few minutes before transferring to a rack. This prevents them from falling apart.
Troubleshooting
- Muffins are too wet or soggy: This is usually due to excess moisture in the zucchini. Make sure to squeeze out as much water as possible before adding it to the batter. Also, double-check that you measured the mashed banana and grated zucchini accurately. Overripe bananas are fine, but if they’re very large, use only about 1 cup mashed.
- Muffins are dense and heavy: Overmixing the batter or not using enough leavening can cause dense muffins. Mix the batter gently and only until just combined. Also, make sure your baking soda is fresh and active.
- Muffins didn’t rise: Check that your baking soda isn’t expired. Muffins also need a hot oven to rise properly, so always preheat before baking.
- Muffins stick to the pan or liners: Grease the tin or use nonstick liners, especially if you’ve reduced the oil in the recipe. Let muffins cool for a few minutes before removing from the pan to help them release easily.
- Muffins are dry: Overbaking is the most common culprit. Start checking for doneness at the earliest suggested bake time. If you live in a dry climate, consider adding an extra tablespoon of oil or applesauce for moisture.
Frequently Asked Questions
- Can I make these muffins gluten-free?
- Yes, you can substitute a 1:1 gluten-free all-purpose flour blend for the regular flour. Check that your baking soda and any add-ins are also gluten-free.
- Can I use frozen bananas or zucchini?
- Frozen bananas work well—thaw and drain off excess liquid before mashing. For zucchini, thaw and squeeze out as much water as possible before using.
- How should I store zucchini and banana muffins?
- Store cooled muffins in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. For longer storage, freeze for up to 3 months.
- Can I reduce the sugar?
- Yes, you can reduce the sugar by 2–4 tablespoons if you prefer less sweetness. The ripe bananas will still provide natural sweetness.
- Can I make these muffins vegan?
- To make vegan muffins, replace the eggs with flax eggs (2 tablespoons ground flaxseed mixed with 5 tablespoons water) and use a plant-based oil. Double-check that all other ingredients are vegan.
- Why do my muffins have green flecks?
- The green specks are from the zucchini skin, which is perfectly safe and adds nutrition and color. If you prefer, you can peel the zucchini before grating.
