  • 2 large eggs at room temperature
  • 60 g coconut oil melted (or neutral oil)
  • 25 g sweetener use granulated sugar or preferred sweetener
  • 75 g dark chocolate chunks or chips minimum 70% cocoa

Dry ingredients

Baking instructions

  • Preheat the oven to 170°C (338°F) with the fan setting or 175°C (350°F) conventional and line a 20×10 cm (9×5 in) loaf pan with parchment paper.
  • Grate the zucchini and squeeze lightly if it releases a lot of liquid so it is damp, not dripping.
  • Whisk eggs with melted coconut oil, then stir in the sweetener and grated zucchini until combined.
  • Sift cocoa, flour, baking powder, baking soda and salt together to remove lumps.
  • Fold dry ingredients into the wet mixture until just combined and stir in chocolate chunks.
  • Pour into the prepared pan and bake for 35–40 minutes or until a toothpick comes out with a few moist crumbs.
  • If the top browns too quickly, tent with foil for the last 10–15 minutes of baking.
  • Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

  • Store cooled slices in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
  • Freeze sliced portions for up to 3 months; thaw at room temperature or warm briefly in the microwave.
  • To reduce sugar, substitute some or all of the sweetener with mashed banana or a low-calorie sweetener and use extra-dark chocolate.
  • For a lighter crumb, replace 30 g of whole-grain flour with 30 g all-purpose flour.
