  • oven
  • food processor or blender



  • C. zucchini roughly chopped into 1" pieces
  • 3 tbsp. butter melted
  • 3 eggs large
  • 1 tsp. vanilla paste vanilla extract works too
  • 1/2 tsp. baking powder
  • 1/2 tsp. espresso powder
  • 1/3 tsp. Kosher salt
  • 1/2 C. all-purpose flour
  • 2/3 C. unsweetened cocoa powder Dutch-processed
  • 3/4 C. granulated sugar
  • 3/4 C. semi-sweet chocolate chips


  • 1/4 C. heavy cream
  • 3/4 C. semi-sweet chocolate chips



  • Preheat oven to 350˚F/177˚C.
  • Lightly butter and line a 9"x9" square baking pan with parchment paper.
  • Into the bowl of a food processor add zucchini, butter, eggs, and vanilla extract. Pulse until completely smooth, scraping down the sides to make sure that there are no chunks of zucchini.
  • Add to the puree, baking powder, espresso powder, salt, flour, cocoa powder, and sugar. Pulse until just combined.
  • Add the chocolate chips and pulse a few times to break the chocolate up slightly.
  • Pour the batter into the prepared pan.
  • Bake for 25-30 minutes or until a toothpick inserted comes out with wet crumbs.


  • In a large microwave-safe bowl combine the chocolate chips and cream.
  • Microwave for 30-second intervals until the chocolate begins to soften and the cream gets steamy. Stir until the chocolate is incorporated into the cream and becomes shiny and smooth.
  • Pour the chocolate on to the completely cooled brownies. Allow the frosting to cool completely for a set frosting or eat warm for a gooey experience. :)
