Instructions

  1. Step 1: Preheat oven to 350°F (175°C). Whisk 1 3/4 cups all-purpose flour, 3/4 cup unsweetened cocoa powder, 1 1/2 cups granulated sugar, 1 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp salt in a large bowl.
  2. Step 2: Beat 2 large eggs, 1 cup buttermilk, 1/2 cup vegetable oil, and 2 tsp vanilla extract into the dry ingredients until smooth, then gradually add 1 cup boiling water while mixing until just combined.
  3. Step 3: Pour batter into a greased 9-inch round pan and bake for 30-35 minutes until a toothpick inserted comes out clean. Cool completely, then whisk 1 cup powdered sugar, 2 tbsp milk, and 1/4 cup heavy cream for the glaze. Drizzle over cooled cake and let set for 20 minutes.

Total time is about 60 minutes (25 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 Best-Kept Secret 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 Best-Kept Secret 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 Best-Kept Secret Chocolate Cake for a different number of people?

The recipe is written for 10 servings. Multiply each ingredient by (your serving target / 10). 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.
