Step‑by‑Step Instructions for Chocolate Dulce de Leche Cake
Step 1: Preheat and Prepare Pans
Preheat your oven to 350°F (175°C). While the oven heats, prepare three 6-inch round cake pans by greasing them with vegetable oil or butter, then dusting the insides with Dutch-processed cocoa powder. This ensures easy release of the cakes once baked, leaving you with perfect layers for your Chocolate Dulce de Leche Cake.
Step 2: Mix Dry Ingredients
In the bowl of a stand mixer, combine 2 cups of all-purpose flour, 1 ½ cups of granulated sugar, ¾ cup of Dutch-processed cocoa powder, 1 ½ teaspoons of baking soda, 1 ½ teaspoons of baking powder, and ½ teaspoon of salt. Mix these dry ingredients on low speed until well combined, about 1 minute. This helps to evenly distribute the leavening agents and flavors throughout the mixture.
Step 3: Combine Wet Ingredients
In a separate mixing bowl, whisk together 1 cup of vegetable oil, 1 cup of buttermilk, ½ cup of hot water, 2 large eggs, and 2 teaspoons of vanilla extract until smooth. Gradually pour this wet mixture into the dry ingredients while mixing on low speed. Continue mixing until just combined, ensuring you don’t overmix—this will keep your cake tender.
Step 4: Bake the Cakes
Divide the cake batter evenly among the three prepared pans, using a kitchen scale for accuracy if desired. Smooth the tops with a spatula and place them in the preheated oven. Bake for 30-35 minutes or until a cake tester inserted in the center comes out clean. Allow the cakes to cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 5: Make Dulce de Leche Buttercream
Prepare your Dulce de Leche buttercream by placing 3 large egg whites and 1 cup of dark brown sugar in a heatproof bowl over simmering water. Whisk continuously until the sugar dissolves and the mixture reaches 160°F (71°C). Remove from heat, and beat on high speed until stiff peaks form, about 5-7 minutes. Let this cool slightly, incorporating 1 ½ cups of cubed unsalted butter and 1 cup of dulce de leche until creamy.
Step 6: Prepare Chocolate Ganache
For the ganache, place 8 ounces of chopped dark chocolate in a microwave-safe bowl. Heat 1 cup of heavy whipping cream in the microwave until just about to boil, then pour over the chocolate. Let sit for 2-3 minutes, allowing the heat to melt the chocolate. Stir until the ganache is smooth and glossy, adjusting the consistency with additional cream if needed.
Step 7: Assemble the Cake
Once the cakes are fully cooled, start layering them with the Dulce de Leche buttercream between each layer. Spread a thin crumb coat over the entire cake and chill it in the refrigerator for 30 minutes. After chilling, pour the chocolate ganache around the edges, allowing some to gently drip down the sides, then decorate the top with extra buttercream as desired, creating a beautiful finish to your Chocolate Dulce de Leche Cake.
