Substitutions and Variations

  • Eggs ? Use flax eggs (1 tablespoon ground flaxseed + 3 tablespoon water per egg) or chia eggs for a vegan option.
  • Greek Yogurt ? Sub with sour cream, plain regular yogurt, or a dairy-free yogurt alternative.
  • Chocolate Chips ? Swap for white chocolate chips, shredded coconut, or chopped nuts (pecans, walnuts, hazelnuts) for crunch.

Variations

  1. Mocha Zucchini Cake ? Add 1 tablespoon instant espresso powder to the batter for a coffee-chocolate kick.

  3. Spiced Chocolate Zucchini Cake ? Add cinnamon, nutmeg, or cardamom for warmth.
  4. Nutty Chocolate Cake ? Mix in toasted walnuts, pecans, or almonds.

  8. Frosting Alternative ? Instead of glaze, top with cream cheese frosting, whipped cream, or dust with powdered sugar.
