Ingredients

Scale
  • 3 ripe bananas, mashed
  • 1/2 cup (115g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 1/2 cups (190g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 teaspoon ground cinnamon (optional)
  • For the Brown Butter Walnut Streusel:
  • 1/4 cup (56g) unsalted butter
  • 1/3 cup (40g) walnuts, roughly chopped
  • 1/3 cup (65g) brown sugar, packed
  • 1/4 cup (30g) all-purpose flour
  • 1/2 teaspoon ground cinnamon
  • A pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 12-cup muffin tin or line with paper liners.
  2. Make the streusel: In a small saucepan over medium heat, melt the butter. Stir until golden and nutty, then remove from heat. Stir in walnuts, brown sugar, flour, cinnamon, and salt until crumbly. Set aside to cool slightly.
  3. In a large bowl, combine mashed bananas, melted butter, sugar, egg, and vanilla extract. Whisk until smooth and creamy.
  4. In a separate bowl, whisk together flour, baking soda, salt, and cinnamon.
  5. Gradually fold dry ingredients into wet banana mixture using a rubber spatula. Stir until just combined; do not overmix.
  6. Spoon batter evenly into muffin cups, filling each about 3/4 full.
  7. Generously sprinkle brown butter walnut streusel over each muffin.
  8. Bake for 18–22 minutes, or until a toothpick inserted near the center comes out clean or with a few moist crumbs.
  9. Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely. Serve warm or at room temperature.

Notes

Use ripe bananas for best sweetness and moisture. Watch the brown butter carefully to avoid burning. Fold batter gently to keep muffins tender. For gluten-free, substitute flour with 1:1 gluten-free blend. For nut-free, replace walnuts with sunflower or pumpkin seeds. Vegan version possible with flax egg and vegan butter substitutes.
