makes 8 large brownies


  • 2 cups white spelt or all purpose flour
  • 1 cup cocoa powder
  • tablespoons baking powder
  • Pinch fine salt
  • ½ cup vegetable oil
  • 1 cup shredded zucchini
  • 1 cup pure maple syrup
  • ½ cup brown rice syrup or agave nectar, or replace with maple syrup
  • ½ cup strong brewed coffee
  • ½ cup milk or soy milk
  • 1 1/2 tablespoons vanilla extract
  • 1 cup high quality chocolate chips


  1. Preheat the oven to 350 F. Line a 9 X 11 inch baking dish with parchment.
  2. Sift the flour, cocoa, baking powder, and salt together in a large mixing bowl.
  3. In a separate bowl, whisk together the ½ cup vegetable oil, shredded zucchini, syrups, coffee, soy milk and vanilla. Mix the wet ingredients into the dry ingredients, being careful not to overbeat.
  4. Pour half the batter into the baking dish. Sprinkle with half the chocolate chips. Pour the rest of the batter into the baking dish, and sprinkle with the rest of the chocolate chips.
  5. Bake for 30 minutes (less if your pan is shallow, more if your pan is deep), or until a toothpick has just a bit of chocolate on it when you test the cake. Cool.

    Amazing! This worked like a charm on my boys. They loved theses gorgeous brownies. I laughed to myself as they ate because they had no clue zucchinis were involved in their after school snack! I myself couldn’t detect any zucchini flavor. And it kind of made it ok for me to eat brownies!

  • Thanks for sharing this, this is such a bakers hack! I’ve never tried zucchini in brownies before, but I have tried it in pancakes – although that recipe went wrong because of the weird ratios I used of other ingredients. I can’t blame the zucchini really! Pinning these, and looking forward to trying them out soon 🙂

  • A great way to use leftover salmon is a salade niçoise. Add potatoes, hard boiled eggs, olives and capers, some greens, and top it all off with a mustardy vinaigrette. Filling, quick, and easy!
