This rich chocolate cake is great for any special occasion. The entire cake is coated with a sweet ganache. It is a moist, fluffy frosted chocolate sheet cake that is perfect for birthdays, celebrations, and more!
Preheat Oven to 350°F/177°C/ Gas Mark 4. Grease and dust a 9 x 13 sheet cake pan with softened butter or cooking spray and cocoa powder.
Coffee - In a large mixing bowl, combine boiling water and coffee. And set aside.
¼ cup Brewed coffee
Dry ingredients - Combine white sugar, brown sugar, flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
2 cups All-purpose flour, ¾ cup Brown sugar, ½ cup White sugar, ½ cup Cocoa Powder, ¾ tsp Baking powder, ¾ tsp Baking soda, ½ tsp Salt
Wet ingredients - In a medium bowl, whip the eggs with buttermilk, cooking oil, and vanilla extract. Then, add the oil followed by the eggs and vanilla. Combine well making sure to break the eggs and incorporate well.
3 large Eggs, ½ cup Buttermilk, ½ cup Cooking oil , 2 tsp Vanilla extract
Wet to dry ingredients - Pour the mixture of liquid ingredients into the dry ingredients (flour mixture) and combine well. Then, add the hot coffee and combine until you have a smooth batter with no lumps.
Bake - Pour batter into the prepared pans. Bake in the center rack for about 25 to 30 minutes or until a toothpick inserted into the center comes out clean.
Cool - Let cool in the pan for 10 minutes. Then, invert onto a wire rack and let cool completely.
Chocolate ganache
Microwave - Chop the chocolate into smaller similar size pieces and place it in a large bowl or measuring cup. Pour the whipping cream over the chocolate. Add the butter and vanilla extract. Combine well. Heat in the microwave for a minute or more until all the chocolate is melted and smooth. Use a whisk to ensure it is smooth. Double boiler - Alternatively, you can heat the cream in a small saucepan over medium heat until it comes to an almost boil. Then, pour the hot cream over the chopped chocolate. Let stand for 2 minutes. Combine with a spatula until it is smooth.
1 lb Chocolate , 1½ cup Heavy cream, 2 tbsp Butter, 1 tsp Vanilla
Chill - Cover the ganache with plastic. Leave to set in the fridge for 2 hours or on the counter for 4 hours until it’s about peanut butter consistency.
Whip - When cooled to peanut butter consistency whip the ganache using a paddle attachment until it is light and fluffy.
Assemble
Syrup - Prepare simple syrup - Cool completely before using. Simple syrup is just sugar water that has been boiled and cooled. Used to keep cake layers moist.
½ cup Simple syrup
Level - Using a bread knife or cake leveler, cut the domes off the sheet cake and brush with the cooled simple syrup.
Frost - Place a sheet cake on the cake board or cake stand. Spread the whipped ganache on top or sides of the cake. Using a paddle motion when spreading will help smooth the ganache better. Place the cake in the fridge to chill for 10 to 15 minutes.
Border - Place some ganache in the piping bag with a star tip and pipe a border all around the top edge of the cake. I also piped the no 50 on the cake using the star tip.
Flowers - I transferred the remaining ganache to a piping bag with Russian piping tips. Hold the bag at a right angle - squeeze and release, until you have piped enough flowers over the cake.
Decorate - I used dragees to dot the flower centers. I also used gold luster dust paint to paint the edges of some of the flowers. This will help create highlights on the cake.
