How To Make Chocolate Sheet Cake Recipe
1. For the Cake:
1. Preheat the oven to 350°F (175°C). Grease and lightly flour a 9×13-inch baking sheet or rectangular baking pan. In a large mixing bowl, sift together the all-purpose flour, light brown sugar, granulated sugar, cocoa powder, baking powder, baking soda, and salt. Mix well until fully combined.
2. To the dry ingredients, add the eggs, buttermilk, vegetable oil, and sour cream. Mix until the batter is smooth and well incorporated.
3. Gradually pour in the hot coffee and vanilla extract. Stir gently to combine, but don’t overmix. The batter will be quite thin—this is normal.
4. Pour the batter into the prepared baking pan. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan on a cooling rack.
2. For the Frosting:
1. In a medium-sized bowl, use an electric mixer to beat the softened butter until light and fluffy. Gradually add in the powdered sugar and cocoa powder, beating until smooth and creamy.
2. Stir in the fudge and salt until fully incorporated. If the frosting is too thick, add a teaspoon of milk at a time until it reaches a spreadable consistency.
3. Once the cake has cooled, spread the frosting evenly over the top of the cake using a rubber spatula or butter knife. Cut the cake into squares and serve. Enjoy your delicious homemade chocolate sheet cake!

If you want to add a touch of flair, consider incorporating a swirl of caramel sauce or a sprinkle of sea salt on top of the frosting.
For a festive twist, you can use colored sprinkles or edible glitter to decorate the cake. This chocolate sheet cake also pairs wonderfully with a scoop of vanilla ice cream, making it a perfect dessert for a casual family dinner or a lively party.

Pro Tips For This Recipe
1. Sift Dry Ingredients: Sift the flour, cocoa powder, baking powder, and baking soda together to ensure they are well-mixed and to avoid lumps in the batter, leading to a smoother texture.
2. Use Room Temperature Ingredients: Bring eggs, buttermilk, and butter to room temperature before mixing. This helps them blend more evenly into the batter, contributing to a consistent crumb and texture.
3. Stir in Boiling Water Carefully: When adding boiling water to the batter, do so slowly and mix gently. This step helps to bloom the cocoa powder, intensifying the chocolate flavor and creating a smoother batter.
4. Cool Completely Before Frosting: Allow the cake to cool completely in the pan on a wire rack before frosting. This prevents the frosting from melting and ensures a clean application.
5. Adjust Frosting Consistency: If your frosting is too thick, gradually add a little more heavy cream until it reaches the desired spreadability. Conversely, if it’s too thin, add a bit more powdered sugar to thicken it.
