Ingredients

Blueberry Zucchini Cupcakes

  • 3 eggs, lightly beaten
  • 1 cup vegetable oil
  • 3 tsp. McCormick® vanilla extract
  • 2 ¼ cup granulated sugar
  • 2 cups finely shredded and drained zucchini
  • 3 cups all-purpose flour
  • 1 tsp. baking powder
  • ¼ tsp. baking soda
  • 1 cup fresh blueberries, you can reserve a few for garnish if so desired
  • 1 tsp. salt

Lemon Buttercream

  • ½ cup butter room temperature
  • 2 cups confectioners sugar
  • Juice of one small lemon about 1 tablespoon
  • 1 tsp. McCormick® vanilla extract
  • tsp. salt

Instructions

  • Preheat oven to 350 degrees F.
  • Grate a large zucchini (or two small zucchini) and place in a clean dish towel. Squeeze until most of the liquid comes out. You will want to have 2 total cups of shredded zucchini after it has been drained. Set aside.
  • In a large bowl and using a hand mixer, beat together the eggs, oil, vanilla, and sugar. Fold in the zucchini.
  • Slowly add in the flour, salt, baking powder, and baking soda. Gently fold in the blueberries. Divide batter evenly in cupcake pan(s).
  • Bake 16-18 minutes in the preheated oven, or until a toothpick inserted in the center of cupcake comes out clean. Cool 20 minutes in pans, then turn out onto wire rack to cool completely.

Lemon Buttercream

  • Combine butter, sugar and salt and beat till well combined.
  • Add lemon juice and vanilla and continue to beat for another 3 to 5 minute or until creamy.
  • Spread buttercream over cooled cupcakes and serve.
  • Add blueberries to top as a garnish.
  • This recipe will yield about 24 cupcakes.
