Ingredients
  

Dry Ingredients

  • 1 3/4 cups all-purpose flour For structure and texture
  • 3/4 cup plain whey protein powder Adds protein and slight thickness
  • 1/2 cup brown sugar, packed Provides moisture and a mild caramel flavor
  • 1/2 teaspoon baking soda Helps with leavening
  • 1 teaspoon baking powder Further supports rise
  • 1 teaspoon salt Enhances flavor

Wet Ingredients

  • 2 cups fresh blueberries, slightly mashed Adds natural sweetness and moisture
  • 1/2 cup grass-fed butter, room temperature Contributes to a tender crumb
  • 1/2 cup sourdough starter, room temperature Adds flavor and moisture
  • 2 teaspoons vanilla extract Provides warmth and depth of flavor
  • 1/3 cup whole milk, room temperature Helps to achieve the right consistency
  • 2 large eggs, room temperature Binds ingredients and provides richness

Instructions
 

Preparation

  • Preheat your oven.
  • In a mixing bowl, combine the all-purpose flour, whey protein powder, brown sugar, baking soda, baking powder, and salt.
  • In another bowl, mix the slightly mashed blueberries with the room temperature butter until creamy.
  • Add the sourdough starter and vanilla extract to the blueberry mixture and stir gently.
  • Pour in the room temperature whole milk and crack in the eggs. Mix until just combined.
  • Slowly fold the dry mixture into the wet ingredients using a rubber spatula.
  • Gentle fold in the remaining fresh blueberries.
  • Line or grease the muffin tin, then spoon the batter evenly into each cup.
  • Place the muffin tin in the preheated oven and bake until the tops are lightly golden and a toothpick comes out clean.
  • Allow the muffins to cool in the tin for a few minutes before transferring them to a wire rack.

Notes

Ensure all ingredients are at room temperature for better mixing. Don’t overfill the muffin tin; three-quarters full allows for optimal rising. Store uneaten muffins for later, as they maintain their comforting flavor even after a day or two.
