Ingredients

Wet Ingredients

  • 113 g salted butter (½ cup)
  • 134 g granulated sugar (⅔ cup)
  • 190 g mashed banana (1 cup; 2 medium or 3 small bananas)
  • 1 large egg
  • 1 tsp vanilla extract
  • 145 g sourdough discard (⅔ cup)

Dry Ingredients

  • 209 g all-purpose flour (1⅔ cups)
  • 1½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt

Add-Ins

  • 75 g chocolate chips (½ cup)
  • 65 g unsweetened shredded coconut flakes, divided (1¼ cups)


Instructions

  1. Preheat and Prepare: Preheat your oven to 425°F (220°C) with the rack in the middle position. Grease a muffin pan or line it with muffin liners to prevent sticking.
  2. Cream Butter and Sugar: In a large bowl, combine 113 g (½ cup) salted butter and 134 g (⅔ cup) granulated sugar. Mix until the butter is soft, light yellow, and fluffy, incorporating air to create a tender muffin texture.
  3. Add Wet Ingredients: To the creamed butter and sugar, add 1 large egg, 1 teaspoon vanilla extract, and 145 g (⅔ cup) sourdough discard. Mix thoroughly until combined, then fold in 190 g (1 cup) mashed banana until evenly distributed.
  4. Mix Dry Ingredients: In a separate medium bowl, whisk together 209 g (1⅔ cups) all-purpose flour, 1½ tsp baking powder, ½ tsp baking soda, and ½ tsp salt.
  5. Incorporate Add-Ins with Dry Ingredients: Add 50 g (approximately 1 cup) unsweetened shredded coconut flakes and 75 g (½ cup) chocolate chips to the dry ingredient mixture. Toss to coat the coconut and chocolate chips evenly with the flour mixture to prevent sinking.
  6. Combine Wet and Dry: Add the dry ingredient mixture to the wet banana mixture. Gently mix until just combined, careful not to overmix to avoid tough, flat muffins.
  7. Fill Muffin Pan: Scoop the muffin batter into the prepared muffin pan, filling each cup to the top for well-shaped muffins.
  8. Add Topping: Sprinkle the remaining 15 g (¼ cup) shredded coconut evenly over the tops of each muffin for a toasted coconut finish.
  9. Bake – First Stage: Place the muffins in the preheated oven and bake at 425°F (220°C) for 5 minutes. This helps the muffins rise quickly, giving a light, airy crumb.
  10. Bake – Second Stage: Without opening the oven door, reduce the temperature to 350°F (175°C) and continue baking for an additional 15 minutes until the tops are lightly golden, spring back when gently pressed, and a toothpick inserted in the center comes out clean.
  11. Cooling: Let the muffins rest in the pan for 2 minutes to set, then transfer them to a wire rack to cool completely to avoid sogginess.
  12. Optional Long Ferment Method: Follow the same batter preparation steps but instead of baking immediately, cover the bowl and refrigerate for 8-12 hours to allow flavors to develop. After refrigeration, bake as directed above.

Notes

  • Nutrition information is automatically calculated and should be used only as an approximation.
  • Do not overmix muffin batter to prevent flat, tough muffins.
  • Cream butter and sugar until butter is light yellow and fluffy to incorporate air bubbles for a tender muffin.
  • Use overripe bananas with dark brown spots for sweeter, moister muffins as sugar content increases with ripeness.
  • You can substitute your favorite chocolate chips, such as semi-sweet, dark, milk, or mini chips, for variation.
