For the Bars:

1 cup grated zucchini
½ cup unsalted butter, softened
1½ cups granulated sugar
2 large eggs
1 teaspoon vanilla extract
1½ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon salt
1 teaspoon ground cinnamon
¼ teaspoon ground nutmeg
¼ teaspoon ground cloves

For the Frosting:

1 cup powdered sugar
2 tablespoons milk (or more, as needed)

Instructions

1. Preheat Your Oven
Set the oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or line it with parchment paper.

2. Make the Batter
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
Beat in the eggs, one at a time, then stir in the vanilla extract.

3. Combine the Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, salt, cinnamon, nutmeg, and cloves.

4. Mix Everything Together
Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Don’t overmix.
Gently fold in the grated zucchini until evenly distributed.

5. Bake the Bars
Pour the batter into the prepared baking pan and spread it evenly.
Bake for 25–30 minutes or until a toothpick inserted into the center comes out clean.
Let cool completely in the pan on a wire rack.

6. Make the Frosting
Whisk together powdered sugar and milk until smooth. Add a little more milk if you prefer a thinner glaze.

7. Frost and Serve
Once the bars are completely cool, spread the glaze evenly across the top.
Cut into squares and enjoy!

Variations

Add-ins: Stir in ½ cup chopped walnuts or pecans for texture.
Chocolate Twist: Add ½ cup mini chocolate chips to the batter.
Cream Cheese Frosting: Swap the glaze for your favorite cream cheese frosting.
