Ingredients

Cake

  • 3 cups grated unpeeled zucchini
  • 3 cups all-purpose flour
  • 1 1/2 tsp baking soda
  • 1 tsp baking powder
  • 3/4 cup white sugar
  • 3/4 cup brown sugar
  • 2 tbsp ground cinnamon
  • 1/2 tsp ground cloves
  • 1/2 tsp ground nutmeg
  • 1 tsp salt
  • 4 eggs
  • 1/3 cup milk
  • 1 cup vegetable oil {can substitute applesauce}
  • 2 tsp vanilla extract
  • 1/2 cup chopped walnuts {optional}

Frosting

  • 2/3 cup butter do not use margarine!
  • 4 cups powdered sugar
  • 2 tsp vanilla
  • 4 tbsp milk

Instructions

  • Preheat oven to 325 degrees F. Grease one jelly roll pan.
  • Grate zucchini and 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, 30-32 minutes. Allow to cool completely before frosting and cutting.

How to Make Frosting

  • In a small saucepan, heat the butter over medium heat, stirring constantly. Cook until butter turns a nice golden brown. It took mine about 5 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.
