Ingredients

2 cups all-purpose flour
1 3/4 cups granulated sugar
3/4 cup unsweetened cocoa powder
1 1/2 tsp baking powder
1 1/2 tsp baking soda
1 tsp salt
1 cup milk
1/2 cup vegetable oil
2 large eggs
2 tsp vanilla extract
1 cup boiling water
1 cup heavy cream
1/2 cup powdered sugar
1 cup cocoa powder
1/2 cup butter
1/4 cup milk
3 cups powdered sugar

Instructions

Step 1: Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line bottoms with parchment paper.
Step 2: Whisk 2 cups all-purpose flour, 1 3/4 cups granulated sugar, 3/4 cup unsweetened cocoa powder, 1 1/2 tsp baking powder, 1 1/2 tsp baking soda, and 1 tsp salt in a large bowl.
Step 3: Add 1 cup milk, 1/2 cup vegetable oil, 2 large eggs, and 2 tsp vanilla extract; mix until combined. Gradually add 1 cup boiling water and mix until smooth.
Step 4: Divide batter evenly between pans (about 2 cups each), smoothing tops.
Step 5: Bake 30-35 minutes until a toothpick inserted comes out clean. Cool in pans 10 minutes, then transfer to wire racks to cool completely.
Step 6: Whip 1 cup heavy cream, 1/2 cup powdered sugar, and 1 tsp vanilla until soft peaks form.
Step 7: Beat 1/2 cup butter until creamy, then add 1 cup cocoa powder, 1/4 cup milk, 3 cups powdered sugar, and 1 tsp vanilla; beat until smooth.
Step 8: Place chocolate layer on plate. Spread half the whipped cream over it, top with vanilla layer, then spread remaining cream. Frost top with chocolate frosting on one half and vanilla frosting on the other half.

How long does Half and Half Chocolate-Vanilla Layer Cake take to make?

Total time is about 80 minutes (45 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 Half and Half Chocolate-Vanilla Layer 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 Half and Half Chocolate-Vanilla Layer 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 Half and Half Chocolate-Vanilla Layer 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.
