1. Prepare the Cake: Start by preheating your oven to 350°F (175°C). Grease and flour three 9-inch round cake pans to ensure easy release.
2. Mix the Dry Ingredients: In a large mixing bowl, whisk together the flour, granulated sugar, brown sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
3. Add Wet Ingredients: Pour in the eggs, milk, vegetable oil, and vanilla extract. Beat the mixture on medium speed for about 2 minutes, until the batter is smooth and free of lumps.
4. Incorporate Boiling Water: Gradually stir in the boiling water. The batter will be thin, which is normal and helps create a moist cake.
5. Bake the Layers: Evenly divide the batter between the three prepared cake pans. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center of the cakes comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
6. Assemble the Cake: Once the cakes are completely cool, place the first layer on a serving plate. Generously spread caramel sauce over the top, then sprinkle with chocolate chips for added texture.
7. Layer and Repeat: Place the second cake layer on top and repeat the process with more caramel sauce and chocolate chips.
8. Finish with the Final Layer: Add the third and final cake layer. Pour the remaining caramel sauce over the top of the cake, letting it cascade down the sides for a dramatic effect.
9. Decorate: Finish by garnishing the top of the cake with chopped chocolate curls, adding a touch of elegance and extra crunch.
