02 - 1 teaspoon baking powder
03 - ½ teaspoon baking soda
04 - ½ teaspoon salt

→ Wet Ingredients

05 - ½ cup unsalted butter, melted
06 - ½ cup active sourdough starter
07 - ½ cup buttermilk or plain yogurt
08 - 1 large egg
09 - 1 teaspoon vanilla extract
10 - ¼ cup granulated sugar
11 - 1 cup fresh or frozen blueberries

→ Optional Add-ins

12 - Zest of one lemon or orange
13 - A sprinkle of cinnamon or nutmeg
14 - A handful of chopped nuts (walnuts, pecans, or almonds)
15 - A drizzle of honey or maple syrup on top before baking

# Instructions:

01 - Gather and measure all ingredients. Preheat oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or grease well.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
03 - In a large bowl, mix melted butter, sourdough starter, buttermilk, egg, vanilla extract, and sugar until well combined.
04 - Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Be careful not to overmix.
05 - Gently fold in the blueberries and any optional add-ins like lemon zest or spices.
06 - For best flavor, cover and allow the batter to rest in the refrigerator overnight. Or proceed directly to baking.
07 - Fill each muffin cup about 3/4 full with batter. If desired, sprinkle with additional toppings or drizzle with honey/maple syrup. Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean.
08 - Allow muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm or at room temperature.

# Notes:

01 - Can use sourdough discard instead of active starter
02 - For buttermilk substitute: Mix 1/2 cup milk with 1/2 tablespoon lemon juice
03 - If using frozen blueberries, don't thaw before adding
04 - Batter can be prepared ahead and refrigerated overnight
