Recipe for a 9x13 sheet cake

  • 1.5 cups grated unpeeled zucchini
  • 1.5 cups all-purpose flour
  • 1 teaspoons baking soda
  • 1/2 teaspoon baking powder
  • 1/2 cups white sugar
  • 1/4 cups brown sugar
  • 2 tsp ground cinnamon
  • 1/4 teaspoon ground cloves
  • 1/4 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 2 eggs
  • 2 TBSP milk
  • 1/2 cup vegetable oil {can substitute applesauce}
  • 1 teaspoon vanilla extract
  • 1/4 cup chopped walnuts {optional}

Pourable Browned Butter Frosting

  • 1/2 cup butter {do not use margarine!}
  • 2- 2 1/2 cups powdered sugar
  • 1 tsp vanilla
  • 1/4 cup milk


Cake Instructions

  • Preheat oven to 325 degrees F. Grease one 9x13 pan.
  • Grate zucchini & set aside.
  • Whisk together the flour, baking soda, baking powder, white sugar, brown sugar, spices and salt in a large bowl until well blended. Beat the eggs, milk, oil, and vanilla in a separate bowl until smooth. Fold in the flour mixture, then stir in the zucchini and walnuts. Pour the batter into the prepared pan.
  • Bake until a toothpick inserted in the center comes out clean, 25-30 minutes. Allow to cool completely before frosting and cutting.

Frosting Instructions

  • In a small saucepan, heat the butter over medium heat, stirring constantly. Cook until butter turns a nice golden brown. It took mine 5-10 minutes and when it turned, it turned very suddenly.
  • Remove from heat. Add in remaining ingredients, stirring until frosting is smooth and spreadable. Spread on cake immediately.
