Description

Moist, cinnamon-spiced zucchini bars topped with creamy frosting – the perfect way to use up fresh summer zucchini while enjoying a bakery-worthy treat.


Ingredients

Scale
  • 1 cup vegetable oil
  • 1 cup granulated sugar
  • 1/2 cup light brown sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1/2 cup quick oats
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 teaspoons ground cinnamon
  • 2 cups grated zucchini (well-drained)
  • 1 package (8 oz) cream cheese, softened
  • 3 tablespoons butter
  • 2 1/2 cups confectioners’ sugar
  • 1 teaspoon vanilla flavoring

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 10.5 x 15.5-inch jelly roll pan or line with parchment paper.
  2. In a large bowl, whisk together vegetable oil, granulated sugar, brown sugar, eggs, and vanilla until smooth.
  3. Add flour, oats, baking powder, salt, and cinnamon. Gently mix until just combined.
  4. Fold in grated zucchini and spread batter evenly in prepared pan.
  5. Bake for 18–22 minutes, or until a toothpick inserted in the center comes out with moist crumbs. Let cool completely.
  6. For frosting, beat cream cheese and butter until fluffy. Gradually add confectioners’ sugar and vanilla, beating until smooth.
  7. Spread frosting over cooled bars, cut into squares, and serve.

Notes

Ensure zucchini is well-drained to prevent soggy texture. Avoid overmixing batter for tender results. Always cool bars completely before frosting.
