Ingredients
Scale
- 1 cup sourdough discard (active or unfed)
- 1 ½ cups all-purpose flour
- ½ cup brown sugar
- 2 large eggs
- ⅓ cup melted butter (or neutral oil)
- ½ cup whole milk
- 1 ½ tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- 1 tsp vanilla extract
Instructions
- Preheat and prep: Heat oven to 425°F and grease or line your muffin tin.
- Mix dry ingredients: Whisk together flour, baking powder, baking soda, salt, and sugar until evenly combined.
- Mix wet ingredients: In a separate bowl, whisk eggs, melted butter, milk, vanilla, and sourdough discard until smooth.
- Combine: Pour wet ingredients into dry, stirring just until combined — a few flour streaks are fine.
- Fold in mix-ins: Gently fold in any add-ins with a rubber spatula without overworking the batter.
- Rest the batter: Let it sit 5–10 minutes to activate the baking powder and hydrate the flour.
- Fill the cups: Fill muffin cups all the way to the top for a tall, domed rise.
- Bake at high heat: Bake at 425°F for 5 minutes without opening the oven door.
- Lower and finish baking: Drop to 375°F and bake 15–18 minutes, until a toothpick in a center muffin comes out with a few moist crumbs.
- Cool: Let muffins cool in the pan 5 minutes before transferring to a wire rack.
Notes
Sourdough Blueberry Muffins — Fold in 1 cup of fresh or frozen blueberries (don’t thaw frozen ones) and a teaspoon of lemon zest. Top with a simple streusel of butter, flour, sugar, and cinnamon before baking.
