Chocolate Zucchini Cake

zucchini chocolate cake

In a good summer, we grow zucchini, lots of zucchini. I love it baked into breaded rounds, diced and added to pasta or other veggie dishes, fried by the panful. But what I end up doing with most of what our garden grows is shredding the zucchini, tucking it into ziplocks stored in the deep freeze and pulling it out all fall, winter and spring. Those little packets of goodness become muffins, savory pancakes and, of course, chocolate cake. If you haven’t tried it before, it can seem odd to add veggies to your dessert. But the zucchini in this recipe works to make this the moistest cake around. Go ahead. Give it a try.

Ganache Icing Ingredients

  • 6 oz heavy cream
  • 1 cup chocolate chips

Ganache Instructions

  1. Heat cream in a saucepan over medium heat until simmering.
  2. Place chocolate chips in a glass bowl. Remove cream from heat and pour over the chocolate chips. Wait 3-5 minutes then stir to combine. It may take a few minutes of stirring for the ganache to come together.
  3. It will thicken as it cools. When it’s warm — not hot — pour over cake and smooth with a spatula. Allow frosting to set for about 30 minutes before serving.
