For the past two weeks, I’ve received four pounds of zucchini in my CSA share. I like zucchini just fine, but it’s not my favorite vegetable, so (with the help of Facebook and Twitter) I crowd-sourced some ideas of what to do with my bounty. Food writer Leah Koenig linked me to her zucchini post on Saveur’s website.
Chocolate Zucchini Cake piqued my interest because of its seemingly bizarre combination of ingredients. The recipe is good — very easy to follow. I, of course, complicated matters because I was missing a few ingredients and had no interest in schlepping out to the grocery store at 9pm. The missing ingredients: corn oil, one of the two eggs, and buttermilk.
- Corn Oil: The only cooking fats in my house last night were virgin coconut oil (I didn’t want to make the cake coco-nutty), butter, ghee, and duck fat. (This is why I need to go grocery shopping sooner rather than later.) I decided to go with melted butter. If I hadn’t just finished all my olive oil, I would have used that as a replacement.
- One Egg: Having gone to a culinary school with a heavily vegan curriculum, I learned that flax seeds can act as egg replacers in baked goods. 1 egg = 1 tablespoon finely ground flax seeds + 3 tablespoons water
- Buttermilk: I happened to have whole milk on hand. Generally, 1 cup buttermilk = 7.5 ounces milk + 1 tablespoon distilled white vinegar or lemon juice.
- 1 tablespoon flax seeds, finely ground
- 3 tablespoons water
- 1 tablespoon distilled white vinegar
- 3 1/2 ounces whole milk
- 2 medium zucchini, trimmed and grated on large holes of box grater
- 9 tablespoons butter, at room temperature
- 2 3/4 cups flour
- 1/4 cup unsweetened cocoa
- 1 1/4 teaspoons baking soda
- 1 teaspoons salt
- 1 1/2 cups sugar
- 1/2 cup butter, melted and cooled slightly
- 1 egg
- 1 teaspoon vanilla extract
- 1/4 cup confectioners sugar
- Make Egg Replacer: stir together ground flax seeds and water. Set aside.
- Make Buttermilk Substitute: stir together vinegar and whole milk. Set aside.
- Working in batches, put a small mound of zucchini in center of large square of double-layer cheesecloth. Gather corners together and squeeze out as much water as possible. Transfer zucchini to a bowl and set aside.
- Preheat oven to 325º. Butter a deep 9″ cake pan with 1 tablespoon of the butter. Sift flour, cocoa, baking soda, and salt together into a mixing bowl and set aside. Beat together remaining 8 tablespoons of butter and sugar in a large bowl with an electric mixer on medium speed until fluffy, 3-4 minutes.
- Add melted butter, beating well. Beat in egg, then egg replacer. Add vanilla, reduce speed to low, and beat in flour mixture and buttermilk substitute in 3 alternate batches. Stir in reserved zucchini.
- Pour batter into prepared pan and bake until toothpick inserted in center comes out clean, about 1 hour and 20 minutes. Remove from oven and set aside to let cool. Invert onto a plate and dust with sugar.
