These frosted zucchini bars are a delightful treat, perfect for using up fresh zucchini from the garden. They're moist, subtly sweet, and topped with a tangy cream cheese frosting.
Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
In a large bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg.
In a separate bowl, beat together the granulated sugar, vegetable oil, eggs, and vanilla extract until well combined.
Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.
Stir in the grated zucchini.
Pour the batter into the prepared baking pan and spread evenly.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Let the bars cool completely in the pan on a wire rack.
While the bars are cooling, prepare the frosting. In a medium bowl, beat the softened cream cheese and butter until smooth and creamy.
Gradually add the sifted powdered sugar and vanilla extract, beating until well combined and smooth. Add a tablespoon of milk if the frosting is too thick.
Once the zucchini bars are completely cooled, spread the cream cheese frosting evenly over the top.
Cut into bars and serve.
Notes
For best results, squeeze out any excess moisture from the grated zucchini before adding it to the batter. Store leftover bars in an airtight container in the refrigerator.
