Easy and delicious, these chewy Cinnamon Frosted Zucchini Cake Bars are the perfect sweet dessert any time of year!


For the cake bars:

  • 1 cup light brown sugar, packed
  • ½ cup unsalted butter, melted
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • ¼ teaspoon kosher salt
  • ½ teaspoon cinnamon
  • 1 cup shredded zucchini

For the frosting:

  • ½ cup unsalted butter, softened
  • 2 ½ cups powdered sugar
  • 1 teaspoon cinnamon
  • 3 Tablespoons milk


  1. Preheat oven to 350°F. Line a 9-inch baking dish with parchment paper, set aside.
  2. In a mixing bowl, combine the brown sugar with melted butter. Add in egg and vanilla. Add flour, salt, cinnamon just until combined. Fold in the zucchini.
  3. Pour batter into prepared dish. Bake for 26-30 minutes, remove from oven and cool completely before frosting.
  4. For the frosting, beat butter with powdered sugar, cinnamon, and milk. Scraping down the sides of the bowl, beat until fluffy, about 3-5 minutes. Spread over cooled cake bars. Refrigerate and enjoy!


  • Be sure to line your pan with parchment paper. These chewy bars can be sticky, and there's nothing worse than not being able to get them out of the pan. Plus it makes them easy to cut and frost too!
  • Make sure your zucchini is shredded and not pureed! A box grater works beautifully for shredding zucchini. A food processor with a grating attachment is a nifty method, too. Be sure not to over process or it could get mushy.
  • If using freshly shredded zucchini, proceed as normal. If using FROZEN, thawed zucchini, you'll want to squeeze out all that excess moisture. Put your zucchini in a piece of cheesecloth, or a very thin towel. Wring the cloth at the top and keep wringing it until all the liquid seeps out (oh, and be sure to do this over the sink, haha)!
  • Allow your bars to cool completely before adding the frosting.
