This recipe is truly the ultimate chocolate sheet cake! Easy to make and every chocolate lover will love it! Make this cake a tradition in your family!
Preheat oven to 350 degrees Fahrenheit.
Mix together flour, sugar and baking soda and sit aside.
In a small saucepan bring to boil 2 sticks of butter, 4 Tablespoons cacao and 1 cup water and pour into flour mixture (I like using the lower part of this double boiler saucepan).
Add eggs, 1/2 cup buttermilk, 1 teaspoon vanilla extract and using an electric hand mixer mix about one minute.
Line a 12×18 sheet cake pan with aluminum foil. You might ask if this necessary. Seriously, I don’t think it really matters but that is the way I have always done it. For one thing it makes for easy clean up and another it saves the pan from being scratched during cutting pieces for serving!
Pour batter into lined sheet cake and bake for 20 minutes. While the cake is baking prepare the frosting. Tip:After the cake has completed baking frost cake while it is still warm and while frosting is hot.
In a small saucepan bring to boil 1 stick butter, 4 Tablespoons cacao, and 6 Tablespoons buttermilk. Remove from heat and stir in 1 box powdered sugar, vanilla extract and 1/2 cup chopped nuts.
While frosting is hot pour over warm cake and smooth out. Top with remaining nuts and allow cake to cool completely.
Enjoy!
