Step 1: Prepare Your Muffin Tin

Start by greasing your muffin tin or lining it with paper liners. This will ensure that your delicious muffins release easily and maintain their shape as they bake.

Step 2: Mash the Bananas

In a mixing bowl, mash 2–3 ripe bananas with a fork until they are smooth. The sweetness of the bananas will be a key note in your muffins, so choose ones that are nicely speckled for optimal flavor.

Step 3: Combine Ingredients

In a large bowl, whisk together the mashed bananas, sourdough starter, sugar, and melted butter. This mixture forms the base of your batter and creates a wonderfully moist texture.

Step 4: Add Dry Ingredients

In another bowl, mix together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring just until combined. Be careful not to overmix, as this could lead to dense muffins.

Step 5: Fold in Optional Add-Ins

If you desire, now is the time to add in any extras such as chocolate chips or walnuts. Gently fold them into the batter for an added crunch or a sweet surprise in each bite.

Step 6: Fill the Muffin Tin

Spoon the batter evenly into the prepared muffin tin, filling each cup about 2/3 full. This allows room for the muffins to rise beautifully without overflowing.

Step 7: Bake

Preheat your oven to 350°F (175°C) and bake the muffins for 20–25 minutes or until a toothpick inserted into the center comes out clean. The aroma will fill your kitchen, making it hard to wait!

Step 8: Cool and Enjoy

Once baked, remove the muffins from the oven and let them cool in the tin for a few minutes before transferring them to a wire rack. Enjoy them warm or store them for a delightful treat later on.
