  • 3/4 cups granulated sugar divided
  • 1/3 cup vegetable oil
  • 1/4 cup unsweetened applesauce
  • 2 eggs
  • 5 ounces buttermilk see note
  • 1 teaspoon baking soda
  • 4 tablespoons unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 2 cups all purpose flour
  • 2 cups shredded zucchini (about 2 small or 1 medium zucchini)

Choose one:

  • 1 1/2 cups chocolate chips OR
  • 1/2 cup cinnamon sugar


  • Preheat oven to 350°F. Spray mini muffin pans with nonstick cooking spray or line regular size cupcake pans with liners.
  • Stir 3/4 cup sugar, oil, and applesauce in a large bowl with a wooden spoon. Stir in eggs, buttermilk, baking soda, cocoa, and salt. Stir in flour. Stir in zucchini.
  • Spoon into muffin pans and bake until a toothpick comes out clean. Cool at least 5 minutes in pan before removing. Regular size muffins: 15-20 minutes. Mini Muffins: 10-12 minutes.
  • Store in an airtight container for up to 3 days or freeze for up to a month.



  1. Make your own buttermilk: add 1/2 teaspoon white vinegar or lemon juice to a measuring cup then add enough milk to make 5 ounces. Let sit 5 minutes.
  2. Looking for the mini doughnut muffins recipe? Make muffins as directed without chocolate chips and without cinnamon sugar topping. Bake in a mini muffin pan for 10-12 minutes. Cool slightly. Before serving, dip each in 4 tablespoons melted butter then toss in cinnamon sugar (1/2 cup sugar + 2 teaspoons cinnamon). Serve immediately.
