Ingredients You’ll Need

Use room temperature ingredients when possible, because they mix more evenly and give the muffins a better texture.

Wet ingredients

2 large eggs
1/3 cup neutral oil (canola, vegetable, or light olive oil)
1/3 cup plain Greek yogurt or sour cream
1 teaspoon vanilla extract (I like Nielsen-Massey, but any pure vanilla works)
3 medium very ripe bananas, mashed (about 1 1/4 cups; plenty of brown spots)
1 cup finely grated zucchini, lightly packed (about 1 small zucchini, no need to peel)

Dry ingredients

1 3/4 cups all-purpose flour (you can swap up to half with white whole wheat flour)
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon fine sea salt
1 1/2 teaspoons ground cinnamon
1/4 teaspoon ground nutmeg (optional but tasty)
1/2 to 3/4 cup granulated sugar or coconut sugar (use 1/2 cup for less sweet, 3/4 cup for bakery-style sweet)

Optional mix-ins

1/2 cup chopped walnuts or pecans
1/2 cup mini chocolate chips or dark chocolate chunks
1/3 cup unsweetened shredded coconut
2 tablespoons coarse sugar for sprinkling on top

Use any combination of mix-ins, but keep the total around 3/4 cup so the batter stays light.

Pantry shortcuts and substitutions

Use store-brand flour and sugar, because they work just as well as premium brands in this recipe.
Swap Greek yogurt with regular yogurt or sour cream if that is what you have.
Use gluten-free all-purpose baking blend in a 1:1 ratio if you need gluten-free muffins.
Use melted coconut oil instead of neutral oil, but cool it slightly before mixing so it does not scramble the eggs.

Equipment list

12-cup standard muffin pan
Paper liners or nonstick spray
Large mixing bowl
Medium bowl (optional, if you prefer to mix dry ingredients separately)
Whisk and rubber spatula
Box grater for zucchini
Fork or potato masher for bananas
Cooling rack

Tips & Tricks

Squeeze the grated zucchini gently in a clean towel if it seems very wet, but keep some moisture so the muffins stay tender.
Use very ripe bananas with lots of brown spots, because they add more sweetness and flavor.
Do not overmix the batter; stir just until the flour disappears so the muffins stay soft.
Fill muffin cups about 3/4 full for nicely domed tops.
Start checking for doneness at 16 minutes, since every oven runs a little different.
Let the muffins cool in the pan for 5 minutes, then move them to a rack so the bottoms do not steam and turn soggy.
Add chocolate chips for kids or nut lovers, and keep a plain batch for breakfast if you prefer less sweetness.
Use an ice cream scoop for even portions and less mess.

How to Make Banana Zucchini Muffins Recipe

Step 1: Prep the pan and oven

Preheat your oven to 350°F. Line a 12-cup muffin pan with paper liners or grease each cup lightly with oil or nonstick spray. Set the pan aside while you mix the batter.

Step 2: Prep the bananas and zucchini

Peel the bananas and mash them in a large mixing bowl with a fork or potato masher until mostly smooth with small lumps. Wash the zucchini and trim the ends. Grate the zucchini on the small holes of a box grater, then lightly squeeze out extra moisture with a clean towel if it feels very wet.

Step 3: Mix the wet ingredients

Add the eggs, oil, yogurt, and vanilla to the mashed bananas. Whisk until the mixture looks smooth and creamy. Stir in the grated zucchini until it spreads evenly through the mixture.

Step 4: Combine the dry ingredients

In a separate bowl, whisk the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and sugar. Break up any clumps of sugar or flour with the whisk. This step helps the leavening spread evenly so the muffins rise well.

Step 5: Bring the batter together

Pour the dry ingredients into the wet ingredients. Use a rubber spatula to fold the mixture together gently until no dry streaks of flour remain. Add any mix-ins like nuts or chocolate chips and fold just a few more times so you do not overwork the batter.

Step 6: Fill the muffin pan

Scoop the batter into the prepared muffin cups, filling each about 3/4 full. Sprinkle the tops with coarse sugar if you want a crunchy lid. Tap the pan lightly on the counter to release any large air bubbles.

Step 7: Bake the muffins

Place the muffin pan on the center rack of the oven. Bake for 16 to 20 minutes, until the tops look golden and a toothpick inserted in the center of a muffin comes out clean or with a few moist crumbs. Rotate the pan once halfway through baking if your oven browns unevenly.

Step 8: Cool and serve

Set the pan on a cooling rack and let the muffins cool in the pan for 5 minutes. Transfer the muffins from the pan to the rack and let them cool at least another 10 minutes. Enjoy warm or at room temperature, and try not to eat three in a row like I usually do.

What to Serve with it?

Serve these banana zucchini muffins warm with a smear of salted butter, almond butter, or peanut butter for extra protein. Pair them with a bowl of Greek yogurt and fresh berries for a quick breakfast that feels balanced and satisfying. Kids love them with a glass of cold milk, and adults can enjoy them with hot coffee, tea, or a cozy mug of hot chocolate. Pack them in lunchboxes with some carrot sticks and apple slices for a simple snack that still feels homemade.

Storage Options

Store cooled muffins in an airtight container at room temperature for up to 3 days, and place a paper towel in the container to catch extra moisture.
Keep muffins in the fridge for up to 5 days if your kitchen runs warm, and let them come to room temperature before eating for the best texture.
Freeze muffins on a baking sheet until firm, then move them to a freezer bag and keep them frozen for up to 3 months.
Reheat muffins in the microwave for 15 to 20 seconds or in a 300°F oven for about 8 minutes, until they feel warm and soft again.
