Ingredients
 
 

Crumb Topping

  • 2 Tablespoons unsalted butter melted
  • ½ cup sugar
  • ¼ cup all-purpose flour
  • pinch fine sea salt

Muffins

  • 2 cups all purpose flour
  • 1 cup sugar
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon fine sea salt
  • 8 Tablespoons unsalted butter melted
  • 2 large eggs room temperature
  • ½ cup sourdough starter discard
  • 2 Tablespoons milk
  • ¼ cup plain Greek yogurt room temperature
  • 1 teaspoon vanilla extract
  • 1 cup blueberries fresh or frozen

Instructions
 

Prepare Crumb Topping

  • In a small bowl, combine the ingredients for the crumb topping:
    2 Tablespoons melted butter, 1/2 cup sugar, 1/4 cup flour, and a pinch of salt.
    Set aside.

Prepare the Muffins

  • Preheat the oven to 350°F. Prepare a 12 count muffin tin with muffin liners or spray with nonstick spray.
  • In a large bowl, combine the dry ingredients:
    2 cups flour, 1 cup sugar, 2 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp salt.
    Set aside.
  • In a smaller bowl, combine the wet ingredients:
    8 T melted butter, 2 eggs, 1/2 cup (120g) sourdough starter discard, 2 Tablespoons milk, 1/4 cup Greek yogurt, 1 tsp vanilla extract.
  • Pour the wet ingredients into the dry ingredients. Stir to combine. If the batter is too thick, add a bit more milk to thin it out. Fold the blueberries into the batter.
  • Scoop the muffin batter into the muffin pan, making 12 large muffins. Sprinkle the crumb topping generously over each muffin.
  • Bake 28-33 minutes or until a toothpick inserted into the center of a muffin comes out clean. Allow muffins to cool in the pan for 10 minutes before transferring to a wire cooling rack.
