These Banana Chocolate Chip Sourdough Muffins are soft, moist, and bursting with sweet banana flavor, melty chocolate chips, and a hint of sourdough tang.
Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with parchment paper liners or grease well.
Mash the bananas in a large mixing bowl until smooth.
Add the wet ingredients: Crack in the egg, pour in the vanilla, melted butter, honey, and sourdough discard. Whisk everything together until fully combined.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Add the dry ingredients to the wet ingredients. Gently fold until just combined—don’t overmix!
Stir in the chocolate chips, reserving a few to sprinkle on top of each muffin if you like that extra chocolatey look.
Spoon the batter into the muffin cups, filling each about ¾ full.
Bake for 15-18 minutes, or until a toothpick inserted into the center comes out clean or with just a few crumbs.
Cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
