Instructions

  1. Step 1: Preheat your oven to 350°F. Grease and flour two 9-inch round cake pans and set aside.
  2. Step 2: In a large mixing bowl, sift together 1 3/4 cups all-purpose flour, 2 cups granulated sugar, 3/4 cup unsweetened cocoa powder, 1 1/2 tsp baking soda, 1 1/2 tsp baking powder, and 1 tsp salt.
  3. Step 3: Add 2 large eggs, 1 cup buttermilk, 1 cup warm water, 1/2 cup vegetable oil, and 2 tsp vanilla extract to the dry ingredients. Using a hand mixer or whisk, beat on medium speed for 2 minutes until the batter is smooth and well combined.
  4. Step 4: Divide the batter evenly between the prepared pans, smoothing the tops with a spatula.
  5. Step 5: Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
  6. Step 6: Remove from oven and allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely before frosting or serving.

Total time is about 50 minutes (15 min prep + 35 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover One-Bowl Classic Chocolate Cake?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in One-Bowl Classic Chocolate Cake?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale One-Bowl Classic Chocolate Cake for a different number of people?

The recipe is written for 12 servings. Multiply each ingredient by (your serving target / 12). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
