With how rich, decadent, and chewy these chocolatey brownies are, no one will be able to tell zucchinis have been secreted in.
Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes
Servings 1 9x13 pan


  • 8 oz zucchini (About a 9 inch zucchini, or about 2 cups shredded)
  • 2 cups flour
  • 1 1/2 cup sugar
  • 1/2 cup Cocoa powder
  • 1/2 tsp espresso powder (Not espresso ground coffee. Can sub for a dark roasted instant coffee)
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 tbs butter, melted
  • 2 eggs
  • 2 tsp vanilla extract


  • Preheat the oven to 350 F. Grease and flour a 9 x 13 baking pan, or line with parchment paper.
  • Combine flour, sugar, cocoa powder, espresso powder, baking soda, and salt in a mixing bowl, stir to evenly combine.
  • Combine the zucchini, butter, eggs, and vanilla in a food processor and pulse until smooth.
  • (Alternatively, if using shredded zucchini, combine butter, eggs, and vanilla in a mixing bowl. Leave out the zucchini for now.)
  • Spoon the wet mixture into the dry and stir until just incorporated. Fold in the walnuts (and shredded zucchini, if using).
  • Transfer the mixture to the prepared baking pan and bake until the brownies spring back when gently touched, about 25-30 minutes.
