Chocolate Zucchini Cupcakes

Just one more way you can use up all those veggies that might be growing in your garden, I love how moist these are, and happy that they have so many veggies as well. I guess it cuts down my guilt when eating them if I think they are full of veggies.

1-1/4 cups butter, softened
1-1/2 cups sugar
2 eggs
1 teaspoon vanilla extract
2-1/2 cups all-purpose flour
3/4 cup baking cocoa
1 teaspoon baking powder
1 teaspoon baking soda
1/2 teaspoon salt
1/2 cup plain yogurt
1 cup grated zucchini
1 cup grated carrots
1 can (16 ounces) chocolate frosting
In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla. Combine the flour, baking cocoa, baking powder, baking soda and salt; add to the creamed mixture alternately with yogurt, beating well after each addition. Fold in zucchini and carrots.
Fill paper-lined muffin cups two-thirds full. Bake at 350° for 18-22 minutes or until a toothpick comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely. Frost cupcakes.
