Chocolate Cake Recipe Bon Appetit

Preheat and Prepare

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. This ensures your cakes will release easily after baking. Tip: Use parchment paper at the bottom of the pans for extra insurance against sticking.

Mix Dry Ingredients

In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Sifting helps to remove any lumps and aerates the flour, leading to a lighter cake.

Combine Wet Ingredients

In another bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract until well combined. The buttermilk adds a slight tang and ensures the cake stays moist. Tip: Room temperature eggs mix more evenly into the batter.

Combine Wet and Dry

Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Then, carefully stir in the boiling water. The batter will be thin, but that’s normal. Tip: The hot water enhances the chocolate flavor, making it more pronounced.

Bake to Perfection

Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Avoid opening the oven door too early to prevent the cakes from sinking.

Cool and Frost

Allow the cakes to cool in the pans for 10 minutes, then turn them out onto a cooling rack to cool completely before frosting. This patience ensures your frosting won’t melt when applied.

Tips and Tricks

For an even more decadent cake, consider brushing the layers with a simple syrup before frosting. This adds moisture and can infuse additional flavors like coffee or liqueur. When measuring flour, spoon it into the measuring cup and level it off with a knife to avoid packing too much flour into your cake. For a professional finish, use a cake turntable when applying frosting. And remember, all ingredients should be at room temperature to ensure a smooth, evenly mixed batter.

Recipe Variations

  • Add a cup of chocolate chips to the batter for extra chocolatey pockets.
  • Incorporate a teaspoon of espresso powder into the dry ingredients to deepen the chocolate flavor.
  • Swap the vanilla extract for almond or peppermint extract for a different flavor profile.
  • Top the frosted cake with fresh berries or a drizzle of caramel for a gourmet touch.
  • Use this recipe to make cupcakes instead of a layer cake; just adjust the baking time to 18-22 minutes.

Frequently Asked Questions

Can I make this cake without buttermilk?

Yes, you can substitute buttermilk by adding 1 tablespoon of vinegar or lemon juice to a cup of milk and letting it sit for 5 minutes before using. This creates a similar acidity that helps tenderize the cake.

How should I store the cake?

This cake can be stored at room temperature, covered, for up to 3 days. For longer storage, refrigerate it for up to a week or freeze the unfrosted layers for up to 3 months.

Can I use a different size pan?

Yes, but baking times will vary. For a 9×13-inch pan, bake for 35-40 minutes. For cupcakes, bake for 18-22 minutes. Always check for doneness with a toothpick.

Summary

This chocolate cake recipe is a foolproof way to satisfy any chocolate craving. With its moist crumb, rich flavor, and simple preparation, it’s sure to become a favorite. Whether you’re celebrating a special occasion or just treating yourself, this cake is a delicious choice.
