Banana Walnut Muffins
Light, tender muffins bursting with sweet banana and crunchy walnuts. Mixed in a single bowl and baked until golden, these classic American muffins are a foolproof breakfast staple. The secret is gentle folding—overmixing makes them dense, so we keep the batter deliberately lumpy for the most tender crumb.
Steps
Before you start
- Preheat your oven to 375°F (190°C)
- Line a standard 12-cup muffin tin with paper liners or lightly grease each cup with butter
- Select 3 ripe bananas with yellow skin and brown speckles—overripe is better than underripe
- Read through the recipe; total time is about 36 minutes from prep to serving
Combine wet ingredients
- Peel the 3 ripe bananas and place them in a large mixing bowl.
- Using a fork, mash them until mostly smooth—a few small lumps are fine.
- Add the 2 large eggs, 1/2 cup (115 g) melted unsalted butter, and 2/3 cup (130 g) granulated sugar to the same bowl.
- Whisk or stir vigorously for about 1 minute until well blended and the sugar is mostly dissolved.
- Stir in 1 teaspoon (5 ml) vanilla extract if using.

Fold in flour and leavening
- Sprinkle the 2 cups (240 g) all-purpose flour, 1 teaspoon (5 g) baking soda, 1/2 teaspoon (2.5 g) baking powder, and 1/2 teaspoon (3 g) salt over the wet mixture.
- Using a spatula or wooden spoon, fold gently until just combined—the batter should look deliberately lumpy and have no dry white streaks.
- Stop folding as soon as the flour disappears.

Tip: Stop folding immediately—lumpy batter yields tender muffins. Overmixing develops gluten and makes them dense and tough.
Fold in walnuts
- Add the 1 cup (115 g) coarsely chopped walnuts to the batter.
- Fold them in gently with just a few strokes of the spatula until evenly scattered throughout.

Ready when: Walnuts are distributed evenly throughout the batter
Fill muffin cups
- Divide the batter evenly among the 12 prepared muffin cups, filling each about 2/3 full.
- A 1/4-cup measure or small ice cream scoop works well for even portions.
- This ensures all muffins bake at roughly the same rate.

Ready when: All 12 cups are filled to roughly the same level
Bake until golden and setOven 375°F / 190°C
- Place the muffin tin in the preheated 375°F (190°C) oven.
- Bake for 20 to 25 minutes, until the tops are golden-brown and a wooden toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs.
- The muffins should feel firm to a light touch on top.

Ready when: Golden-brown muffin tops; toothpick comes out clean or with just a few crumbs
Tip: If the tops are browning too quickly but the centers aren't set, tent loosely with foil for the last 5 minutes. Slightly underdone is better than dry.
Cool and serve
- Remove the muffin tin from the oven and let the muffins cool in the tin for 5 to 10 minutes.
- This allows them to set slightly so they don't crumble when removed.
- Gently turn them out of the cups onto a wire cooling rack.
- Serve warm or at room temperature.

Good to know
Tips
- Select ripe bananas with golden skin and brown speckles for sweetness. If bananas are underripe or green, they won't add enough flavor.
- Lumpy batter is your friend—it yields tender, soft muffins. Mix just until the flour disappears; don't stir out every bump.
- For extra-moist muffins, let the filled batter cups rest at room temperature for 10 minutes before baking. This allows the flour to fully hydrate.
- A muffin tin with a darker or nonstick surface may brown the bottoms faster. If they're browning too quickly, reduce the oven temperature by 25°F (14°C).
Make ahead
Yes. Bake muffins up to 1 day ahead, cool completely, and store in an airtight container at room temperature. You can also freeze baked muffins in a freezer bag for up to 3 months. Thaw at room temperature (2–3 hours) or reheat wrapped loosely in foil at 300°F (150°C) for 10 minutes until warmed through.
Storage & reheating
Room temperature in an airtight container for up to 2 days. Refrigerate in an airtight container for up to 4 days. Freeze baked muffins in a freezer bag for up to 3 months. Thaw at room temperature or reheat wrapped in foil at 300°F (150°C) for 10 minutes.
Substitutions
- walnuts → chopped pecans, almonds, or hazelnuts. Pecans add a sweeter, buttery note; almonds contribute a delicate flavor. Use the same amount by volume.
- unsalted butter → neutral vegetable oil or melted coconut oil. Oil produces slightly more tender and moist muffins. Use the same amount by volume.
- granulated sugar → packed brown sugar. Brown sugar adds caramel notes and makes muffins slightly moister. Use the same volume; it will pack down more, so measure carefully.
- all-purpose flour → whole wheat flour or spelt flour (use for half the all-purpose flour). Substituting half the flour with whole grains adds earthiness and fiber. Avoid replacing all the flour, as it makes muffins too dense.
