The Best Chocolate Cake Recipe

Preheat your oven to 325°F (160°C). Grease two 9-inch cake pans, dust them with flour, and line the bottoms with parchment paper circles to prevent sticking and ensure even baking.

In a medium saucepan over medium heat, melt 1 cup of salted butter. Stir in 1 cup water and 1/2 cup cocoa powder, whisking until smooth. Bring the mixture to a gentle boil for 30 seconds, then remove from heat and let it cool to room temperature.

In a large bowl, whisk together 1 cup white sugar, 2 cups sifted flour, and 3/4 teaspoon salt to combine the dry ingredients evenly.

In another medium bowl, lightly beat 2 eggs. While whisking, gradually sprinkle in 1 teaspoon baking soda and 1/2 teaspoon baking powder. Then stir in 2 teaspoons vanilla extract and 1 cup dark brown sugar until well combined.

Add the cooled chocolate mixture to the flour mixture and stir gently until just combined. Next, mix in the egg mixture until incorporated. Finally, fold in 1/2 cup sour cream gently to maintain a tender crumb; avoid overmixing.

Divide the batter evenly between the prepared pans. Tap the pans on the countertop to release any air bubbles. Bake in the preheated oven for 34-40 minutes, rotating the pans halfway through baking. The cakes are done when a toothpick inserted into the center comes out clean.

Allow the cakes to cool in the pans for 10 minutes. Then invert onto a wire rack to cool completely. Wrap each cake tightly in plastic wrap and freeze for 1-2 hours; this step firms up the cakes to make frosting easier and neater.

Using a mixer, cream 1 ½ cups softened salted butter until smooth. Gradually add 3/4 cup cocoa powder and 5 1/4 cups powdered sugar in portions, alternating with 3/4 cup heavy cream. Beat well after each addition for a creamy texture. Mix in 3/4 teaspoon salt and 2 teaspoons vanilla extract to enhance the flavors.

Place a small dab of frosting on your cake plate to secure the first cake layer. Spread 1 cup of frosting evenly over the top of the first layer. Position the second cake layer on top. Frost the sides and top of the cake smoothly. For a tidy finish, line the cake plate edges with parchment strips while frosting, then carefully remove them once completed.

Slice the cake and enjoy its rich chocolate flavor with a glass of milk. Store any leftovers covered at room temperature for up to two days or in the refrigerator for longer freshness.
