The Best Chocolate Zucchini Cake

Happy birthday to me. Thirty-four years old. One year cancer-free. Almost divorced. Mother of two. Owner of one three-legged pit bull, one garden, and one cast iron skillet that has been in continuous service since 2006. I am alive and solvent and standing in my own kitchen making my own birthday cake, because no one else is going to do it and I have decided that baking your own birthday cake is not pathetic. It is self-sufficient. It is Dawson.

I made a chocolate cake — not from a box, from scratch, because I wanted the work of it. Beating butter and sugar until fluffy. Sifting cocoa and flour. Folding in the batter with the kind of attention I used to give only to veterinary procedures. Two layers, chocolate frosting, sprinkles (because Lily demanded sprinkles, and the birthday baker gets to include whatever the birthday baker wants). I wrote "Happy Birthday Mama" in frosting on top, and it was crooked and the letters ran together and it was perfect.

Brett and Claire came for dinner. Carol brought flowers. Mom called at 7 AM — "I wanted to be the first one" — and Dad got on the phone and said, "Happy birthday, kid. Thirty-four looks good on you," which is what he said at thirty-three and thirty-two and every year before that, because Gary Dawson has one birthday compliment and he delivers it with consistency. Kyle texted from Germany: "HB sis." Two words. Perfectly Kyle.

Mason gave me a card he'd made at school — a drawing of me in the garden with tomatoes and Hank and curly hair. The curly hair is prominent. He has decided that my curly hair is the defining feature of New Mama, as opposed to Old Mama who had straight hair. I like New Mama better, he said. "She smiles more." I don't know if this is true. I don't know if I smile more. But he sees what he sees, and what he sees is a mother who is present, who is cooking, who is here, and he calls that smiling, and maybe he's right.

Lily gave me a rock. A smooth gray rock from the playground that she'd been carrying in her pocket for three days. She said, "It's a birthday rock, Mama. It's lucky." I put it on my nightstand next to Mom's note from last year — the "you are the strongest person I know" note — and now my nightstand has a note from my mother and a rock from my daughter, and together they are the most valuable things I own.

For my birthday dinner, I made what I wanted: steak. A good ribeye, seasoned with salt and pepper, cooked in the cast iron skillet, medium-rare. Baked potatoes. A green salad from the garden. Simple, ranch, mine. I ate it at the table with Brett and Claire and the kids and Hank at my feet, and the cake was waiting on the counter, and the candles were waiting to be lit, and I was thirty-four and alive and the woman I am now is not the woman I was a year ago. She is harder, softer, braver, more afraid, more grateful, more tired, more awake. She is all of it. And she is eating her own steak and she baked her own cake and she is fine. She is better than fine. She is here.

The cake I made that birthday was chocolate, from scratch, two layers — and if I’m honest, I’ll tell you I snuck shredded zucchini from the garden into the batter, because I have a garden and a cast iron skillet and a deep personal belief that vegetables belong in birthday cake if you grew them yourself. This is the recipe I’ve landed on: deeply chocolatey, impossibly moist, the kind of cake that tastes like you meant it. Frost it, add sprinkles if your kid demands them, write something crooked on top. You earned it.

Prep Time: 20 min | Cook Time: 40 min | Total Time: 1 hr | Servings: 12

Ingredients

2 cups all-purpose flour
3/4 cup unsweetened cocoa powder
2 teaspoons baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
1 teaspoon espresso powder (optional, deepens chocolate flavor)
3/4 cup unsalted butter, softened
1 1/2 cups granulated sugar
2 large eggs, room temperature
2 teaspoons pure vanilla extract
1/2 cup sour cream or plain full-fat yogurt
1/2 cup whole milk
2 cups finely shredded zucchini (do not wring dry)
1 cup semi-sweet chocolate chips

For the Chocolate Frosting

1 cup unsalted butter, softened
3 cups powdered sugar, sifted
1/2 cup unsweetened cocoa powder, sifted
3–4 tablespoons heavy cream or whole milk
1 teaspoon vanilla extract
Pinch of salt
Sprinkles, as demanded

Instructions

Preheat and prep. Preheat your oven to 350°F. Grease two 9-inch round cake pans and line the bottoms with parchment paper. Set aside.
Combine dry ingredients. In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and espresso powder if using. Set aside.
Cream butter and sugar. In a large bowl, beat the softened butter and sugar together on medium-high speed until light and fluffy, about 3–4 minutes. Don’t rush this part — it matters.
Add eggs and vanilla. Beat in the eggs one at a time, then add the vanilla extract. Mix until fully combined and smooth.
Add sour cream. Mix in the sour cream until incorporated.
Alternate dry and wet. With the mixer on low, add the flour mixture in three additions, alternating with the milk in two additions (flour, milk, flour, milk, flour). Mix just until combined after each addition — do not overmix.
Fold in zucchini and chips. Using a rubber spatula, gently fold in the shredded zucchini and chocolate chips. The batter will be thick. This is correct.
Bake. Divide the batter evenly between the prepared pans. Bake for 35–40 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs. Do not overbake.
Cool completely. Let cakes cool in the pans for 15 minutes, then turn out onto a wire rack and cool completely before frosting. Completely. If you frost a warm cake the frosting will slide and you will have feelings about it.
Make the frosting. Beat butter on medium-high until very pale and fluffy, about 3 minutes. Add cocoa powder and powdered sugar one cup at a time, beating between additions. Add vanilla, salt, and cream one tablespoon at a time until you reach a thick, spreadable consistency.
Frost and decorate. Place the first cake layer on your serving plate. Spread a generous layer of frosting on top. Add the second layer. Frost the top and sides. Write whatever you want on it. Add the sprinkles. The letters can run together. It’s yours.
