Chocolate Zucchini Cake with Chocolate Buttercream

You would never have known that this innocent looking chocolate cake would be chock full of vegetables!

For my mom's birthday, I decided to make this chocolate zucchini cake. I purchased some zucchini because I had plans on making chocolate chip cookies with them. I didn't make them yet, but since I was going to need to use them up, I made this cake. I figured if carrot cake is one of my faves, why not zucchini!

This cake came out beautifully and nobody knew there were hidden vegetables inside! My little cousins ate up big slices and gobbled it up just like any old chocolate cake! However, I'm not saying this is a healthy cake, since it does have a lot of oil in it! I originally intended to use some applesauce in place of some oil, but I noticed it was already expired, (whoops). I also don't know what the nutritional value of the zucchini ends up being after it's baked into a cake.

Even after I mixed in the eggs and oil, I thought the batter looked a little stiff, almost cookie batter-like. However after I folded in the zucchini, it was fine and easily pour-able. I used my food processor to grate the zucchini, and I did not squeeze out any liquid.

I did change this from a bundt cake recipe to a layer cake one. I omitted the nuts since I didn't have any on hand. For the frosting, I reduced the amount of sugar by 1/4 cup from the original recipe.

*note: this is tagged as dairy free, as the cake itself is dairy free. For a dairy free/vegan chocolate frosting option, see this cupcake recipe.

ingredients:
2 cups all-purpose flour
2 cups white sugar
3/4 cup unsweetened cocoa powder
2 teaspoons baking soda
1 teaspoon baking powder
1/2 teaspoon kosher salt
1 teaspoon ground cinnamon
4 large eggs
1 1/2 cups vegetable oil (or replace some with applesauce)
3 cups grated zucchini (about 2 medium)

9 oz semisweet chocolate, melted and cooled to lukewarm
3 sticks (1.5 cups) unsalted butter, softened
2 TBSP milk
1 tsp vanilla extract
2 cups powdered sugar, sifted

directions: 
bake the cake: 
Preheat oven to 350° F (175° C). Grease and flour two 8 or 9 inch round cake pans.

In a medium bowl, stir together the flour, sugar, cocoa, baking soda, baking powder, salt and cinnamon. Add the eggs and oil, mix well. Fold in zucchini until it is evenly distributed. Pour into the prepared pans.

Bake for 30 minutes in the preheated oven, until a toothpick inserted into the center comes out clean. Transfer to wire racks and cool cake completely before frosting.

prepare frosting: 
In a medium saucepan bring an inch of water to a boil. Reduce heat to low to simmer. Place chocolate in a glass or heat proof bowl over the simmering water and mix to melt the chocolate. Once all the chocolate is melted, remove from heat, set aside and let cool to room temperature, 5-15 minutes.

Meanwhile, on medium speed beat butter in an electric mixer for 3 minutes until smooth and creamy.

Slowly pour in milk and continue to beat for 2 minutes. Add vanilla and beat for 3 more minutes. Add in powdered sugar in small increments and beat at low speed until it reaches the desired consistency.

Frost cake as desired.
