  • Use finely shredded zucchini so it blends seamlessly into the batter.

  • Top with extra chocolate chips before baking for bakery-style muffins.
  • Let them cool fully for the richest chocolate flavor and best texture.

Storing – Store muffins in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
