    Ingredients for Chocolate Zucchini Bars

    Ingredients for chocolate zucchini bars.
    • eggs
    • vegetable oil 
    • sugar
    • all purpose flour
    • baking soda
    • kosher salt
    • ground cinnamon
    • unsweetened cocoa powder
    • pure vanilla extract
    • zucchini
    • cream cheese frosting (optional)

    See recipe card for quantities.

    Instructions

    Pale yellow liquid being poured from a bottle of sunflower oil into a metal jelly roll pan.

    Heat the oven to 350℉ and lightly grease a standard size jelly roll pan (15"x10"x1") with oil.

    A pile of shredded zucchini next to a box grater on a dark gray cutting board.

    Shred the zucchini. (The large holes on a box grater work best for this task.)

    Sugar being poured from a steel measuring cup into a glass bowl containing eggs and vegetable oil.

    In a large bowl, beat together the eggs, vegetable oil, and sugar with an electric mixer for 2 minutes.

    Light brown powder in a steel measuring cup being held over a glass bowl containing flour and cinnamon next to a package of cocoa.

    In a medium bowl, whisk together the flour, baking soda, cinnamon, salt, and cocoa.

    Dry ingredients being stirred into wet ingredients with a white silicone spatula in a glass bowl.

    Add the dry ingredients to the wet ingredients all at once, and then mix well by hand until smooth.

    Deep brown liquid being tipped out from a steel measuring spoon into a glass bowl of chocolate batter and shredded zucchini next to a bottle of vanilla extract.

    Then add the vanilla and the shredded zucchini and stir by hand until the batter looks well combined.

    Brown batter flecked with shredded zucchini being poured from a glass bowl into a jelly roll pan.

    Pour the batter into the greased jelly roll pan.

    A pan of chocolate zucchini bars baking in a blue oven.

    Bake for 25 to 30 minutes, or until the edges begin pulling away from the sides of the pan.

    Then cool completely in the pan.

    Cream cheese frosting being spread over a pan of chocolate zucchini bars with an offset spatula.

    If desired, spread a thin layer of cream cheese frosting evenly over the top before cutting into bars.

    Hint: All that shredded zucchini lends a naturally tender crumb to these cake-like dessert bars, but it is still important not to overbake them. Check frequently for doneness near the end of their cooking time.

    Variations

    • Add Nuts - Chocolate zucchini bars are even better when they are laced with nuts for a bit of crunch...try mixing in a cup of chopped walnuts or pecans along with the shredded zucchini.
    • Play with Spices and Flavorings - Don't adore cinnamon? Simply omit it. Feeling a bit adventurous in the spice arena? Perhaps try adding some cardamom, allspice, cloves, or a pinch of cayenne. Prefer more intensity when it comes to your chocolate? Add a couple teaspoons of instant espresso powder to the mix when combining the wet ingredients.
    • Chocolate on Chocolate - If topping the bars with cream cheese frosting, make it a chocolate cream cheese frosting by adding three tablespoons of cocoa along with the powdered sugar.

    Equipment

    Don't have a jelly roll pan? You can also use a rimmed cookie sheet here, as long as the dimensions are similar. For instance, a rimmed cookie sheet measuring about 17"x12" works just fine for this recipe...the bars will turn out slightly shorter in height, but they will still be sensational.

    Storage

    Chocolate zucchini bars will keep well for at least a few days when covered with plastic wrap or stored in an airtight container. If topped with cream cheese frosting, they should be placed in the refrigerator.
