  • buttermilk or substitute: 1 to 2 tablespoons lemon juice or vinegar mixed with 1 cup milk
  • blueberries fresh or frozen
  • zucchini

Instructions
 

  • Line a baking pan with parchment paper for easy removal and cleanup.
  • If using frozen blueberries, add them directly to the batter without thawing to prevent discoloration.
