Ingredients for the Perfect Classic Chocolate Cake

For the Chocolate Cake:

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 3/4 cup Dutch-processed cocoa powder, sifted
• 2 tsp baking soda
• 1 tsp baking powder
• 1 tsp salt
• 1/2 cup vegetable oil
• 1 cup buttermilk, room temperature
• 1 cup hot water
• 2 large eggs, room temperature
• 2 tsp vanilla extract

For the Chocolate Swiss Meringue Buttercream:

• 5 large egg whites
• 1 1/2 cups granulated sugar
• 1 1/2 cups unsalted butter, room temperature
• 8 oz dark chocolate, chopped, melted, and cooled

For Assembly:

• Chocolate curls, pearls, or sprinkles (optional)

Step-by-Step Instructions

🍰 Make the Chocolate Cake:

1. Prep the pans: Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and dust with cocoa powder. Line the bottoms with parchment paper.
2. Mix dry ingredients: In the bowl of a stand mixer fitted with a paddle attachment, stir together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
3. Combine wet ingredients: In a separate bowl, whisk the eggs, buttermilk, oil, vanilla, and hot water (slowly so the eggs don't cook).
4. Combine wet and dry: Pour the wet ingredients into the dry mixture. Mix on medium speed for 2–3 minutes. The batter will be thin—don't worry, that’s perfect.
5. Bake: Divide the batter evenly between the two prepared pans. Bake for 40–45 minutes, or until a toothpick comes out with just a few moist crumbs.
6. Cool: Let cakes cool in the pans for 10 minutes, then turn out onto wire racks to cool completely.

🍫 Make the Swiss Meringue Buttercream:

1. Create the meringue base: In a clean, grease-free bowl of a stand mixer, combine egg whites and sugar. Whisk to combine.
2. Heat gently: Place the bowl over a double boiler and whisk constantly until the sugar dissolves and the mixture reaches 160°F (71°C). It should feel smooth when rubbed between your fingers.
3. Whip it up: Transfer the bowl to the stand mixer. Whisk on medium-high until stiff peaks form and the bowl is cool to the touch (5–10 minutes).
4. Add butter: Switch to the paddle attachment. Add cubed butter one piece at a time, mixing well after each addition. Don’t worry if it looks curdled—it’ll come together.
5. Add chocolate: Once the buttercream is smooth, pour in the cooled melted chocolate and mix until fully combined.

🎂 Assemble the Classic Chocolate Cake:

1. Layer: Place one cake layer on a serving plate. Spread 1 cup of buttercream on top. Add the second cake layer.
2. Crumb coat: Apply a thin layer of frosting around the cake to seal in crumbs. Chill for 20 minutes.
3. Frost: Apply the remaining frosting evenly on the top and sides of the cake. Smooth the surface or create a swirl pattern using an offset spatula.
4. Decorate: Add chocolate curls, pearls, or sprinkles for a touch of elegance.

Pairing Suggestions
