Notes
Measuring Flour: For best results, weigh the flour in grams using a scale (see metric tab in recipe card above). If you're using measuring cups, use the spoon and level method.Sourdough Discard: This is the part of the sourdough starter that does not get fed. Fed sourdough starter can be used but is not recommended as it may yield muffins with a floury flavor.Storage: Store muffins in an airtight container at room temperature for 3 days or in the freezer for 1 month.Regular Muffins: Distribute the batter between 12-14 regular muffin liners and bake at 375°F for about 13-18 minutes.Mini Muffins: Bake 24-28 mini muffins at 350°F for 10-15 minutes.Nutrition: The provided nutrition information is an estimate, the calorie accuracy is not guaranteed.
