These muffins are the kind of breakfast that makes an ordinary morning feel special without requiring complicated equipment or hard-to-find ingredients. The recipe uses one bowl for the wet mixture, one bowl for the dry mixture, and a standard 12-cup muffin pan.
Very ripe bananas provide most of the signature flavor and help create a moist, tender crumb. Melted unsalted butter adds a buttery richness, while walnuts bring a pleasant contrast to the soft banana center.
The muffins are sweet enough to enjoy on their own but not so sugary that they feel like dessert. Serve them warm with coffee, tea, or a glass of milk, or pack one for a quick breakfast on a busy day.

Ingredients You’ll Need
Each ingredient has a clear job in this straightforward muffin formula. Measure the flour carefully, mash the bananas well, and have the butter melted and slightly cooled before combining the wet ingredients.
- All-purpose flour: The structure for the muffins comes from 1 1/2 cups, or 188 grams, of flour.
- Baking soda and baking powder: One teaspoon of each helps the batter rise and keeps the muffins light.
- Salt: A half teaspoon balances the sweetness and sharpens the banana and butter flavors.
- Very ripe bananas: Use three large bananas, mashed to about 1 1/4 cups. Heavily speckled or mostly brown fruit is ideal.
- Granulated sugar: Three-quarters cup, or 150 grams, provides sweetness and supports a tender texture.
- Egg: One lightly beaten large egg helps bind the mixture.
- Unsalted butter: One-third cup, or 75 grams, contributes moisture and a rich, satisfying flavor.
- Walnuts: Use 1/2 cup, or 55–60 grams, of chopped walnuts for crunch throughout the muffins.
If you prefer a slightly deeper walnut flavor, toast the chopped nuts before starting. Spread them on a dry baking sheet and warm them briefly until fragrant, then cool them before folding them into the batter.
How to Make It Step-by-Step
Step 1: Heat the oven to 375°F (190°C), which gives the muffins the correct baking temperature from the beginning. Line a 12-cup muffin pan with paper liners, or grease each cup lightly so the muffins release easily after cooling.
Step 2: Add the all-purpose flour, baking soda, baking powder, and salt to a medium bowl. Whisk until the leavening agents and salt are distributed evenly through the flour, which helps every muffin rise consistently.
Step 3: In a separate bowl, mash the three very ripe bananas until mostly smooth, leaving only a few small pieces if you like a little extra banana texture. Stir in the sugar, lightly beaten egg, and melted butter that has cooled slightly.
Step 4: Add the dry mixture to the bowl of banana mixture. Stir gently just until no dry flour remains; the batter may look a little lumpy, and that is exactly what you want for tender muffins.
Step 5: Fold in the chopped walnuts using a spatula or large spoon. Use only a few gentle turns so the nuts remain distributed without causing the batter to become dense from excessive mixing.
Step 6: Divide the batter among the prepared muffin cups, filling each about two-thirds to three-quarters full. A large cookie scoop or about 3 tablespoons of batter per cup makes it easier to create evenly sized muffins.
Step 7: Place the pan in the hot oven and bake for 18–22 minutes. The tops should be lightly golden, and a toothpick inserted into the center should come out clean or with a few moist crumbs.
Step 8: Let the muffins cool in the pan for about 5 minutes so their crumb can set without drying out. Transfer them to a wire rack and serve warm or allow them to cool completely before storing.
Pro Tips for Soft, Flavorful Muffins
The bananas matter more than any other flavoring in this recipe. Barely ripe bananas can produce muffins that are less sweet, less fragrant, and not as moist, so wait until the peels are heavily speckled or mostly brown.
Do not try to beat the batter smooth after the flour is added. A few small lumps are harmless, while prolonged stirring can develop too much gluten and leave the finished muffins dense or chewy.
- Cool the butter slightly: Very hot butter can make the egg mixture less smooth, so let it stand briefly after melting.
- Use a scoop: Consistent portions help all 12 muffins finish baking at about the same time.
- Check early: Begin checking at 18 minutes because oven performance and muffin pan materials can vary.
- Toast the walnuts: Cooling toasted walnuts before adding them keeps their texture crisp and their flavor full.
- Do not overbake: Remove the pan when the toothpick shows a few moist crumbs rather than waiting for it to come out completely dry.

Storage, Freezing, and Serving
Once completely cool, store the muffins in an airtight container at room temperature. They are best enjoyed within a few days, when the crumb remains soft and the walnuts retain their pleasant bite.
To warm one, heat it briefly until just cozy, taking care not to dry the crumb. A muffin is delicious plain, but you can also serve it with softened butter, cream cheese, or a spoonful of yogurt.
For longer storage, place the cooled muffins in a freezer-safe container or bag with parchment between layers. Thaw them at room temperature, then warm gently before serving for a breakfast that tastes freshly baked.
These muffins also make a thoughtful addition to a brunch table. Arrange them in a lined basket with fresh fruit, coffee, and tea for an inviting spread.
Simple Ways to Enjoy Banana Muffins
The classic combination of banana and walnut needs very little adjustment, but small serving changes can make the muffins feel new each time. Split a warm muffin in half and add a little butter, or crumble one over yogurt with fresh berries.
They are also useful for breakfast preparation because the individual portions are easy to grab. Bake a batch when your bananas are ready, cool them fully, and keep them available for school mornings, office snacks, or weekend brunch.
