I love it when my nieces visit The Farm. Their humor and personalities give me so much joy! Every time we’re together they want to bake together and I have no problem with that! I’ve made this previously but hadn’t brought it to you in a video. So I’ve updated the recipe just slightly, but this is still the cake I grew up with. When you have an abundance of zucchini – and if you grow it, you most certainly do – this is a perfect way to use it!

Ingredients

For the cake

  • 8 tbsp (1 stick) unsalted butter room temperature
  • ½ cup neutral oil
  • 1 ¾ cups granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • ½ cup buttermilk or sour milk (2 tsp vinegar with ½ cup milk)
  • 2 ½ cups all-purpose flour
  • 4 tbsp Dutch-process cocoa powder
  • ½ tsp baking powder
  • 1 tsp baking soda
  • ½ tsp kosher salt
  • ¾ tsp ground cinnamon
  • ¾ tsp ground cloves
  • 2 cups grated zucchini seeds removed
  • ½ cup chocolate chips (miniature variety preferred)

For the ganache

  • 4 oz semi-sweet chocolate
  • ½ cup heavy cream

Instructions 

For the cake

  • Preheat oven to 350°F.
  • Prepare zucchini by cutting off ends, scooping out seeds, and grating. Set aside. I like to leave the skin on but it can also be peeled.
    2 cups grated zucchini
  • Cream together butter, oil, and sugar until light and fluffy, 4 minutes.
    8 tbsp (1 stick) unsalted butter, ½ cup neutral oil, 1 ¾ cups granulated sugar
  • Add eggs, one at a time, and vanilla extract, and mix until incorporated.
    2 large eggs, 1 tsp vanilla extract
  • In a separate bowl sift together the flour, cocoa, baking powder, baking soda, salt, cinnamon, and cloves.
    2 ½ cups all-purpose flour, 4 tbsp Dutch-process cocoa powder, ½ tsp baking powder, 1 tsp baking soda, ½ tsp kosher salt, ¾ tsp ground cinnamon, ¾ tsp ground cloves
  • Alternately add the dry ingredients with the buttermilk in three additions, beginning and ending with the dry.
    ½ cup buttermilk or sour milk (2 tsp vinegar with ½ cup milk)
  • Stir in zucchini and chocolate chips.
    ½ cup chocolate chips (miniature variety preferred)
  • Spray pans with nonstick baking spray and fill with batter. Bake until a toothpick inserted in middle comes out clean, about 20 minutes. I used miniature Bundt pans, which makes approximately 18 cakes. You can also make one large Bundt cake. Increase baking time to 45-60 minutes.
  • Remove from oven and cool in the pan for 5 minutes then turn out onto cooling rack.

For the ganache

  • Prepare ganache by heating heavy cream until steaming.
    ½ cup heavy cream
  • Pour over the chopped chocolate and stir until smooth and melted.
    4 oz semi-sweet chocolate
  • Drizzle ganache on slightly cooled cakes.

    Well I have this cake in the oven now. I watched you make this cake. It looks really good. I have not had a zucchini cake or loaf made with chocolate and spices. I chose to do pecans as I didn’t have chocolate chips. I’m anxious to try it. I just had a slice after cooling. So good! This will be a keeper for me. I have not put the drizzle on as I don’t have those ingredients on hand but delicious by itself. Going to share this with a neighbour.
