2 cups (260g) flour
2 cups (414g) sugar
3/4 cup (85g) natural unsweetened cocoa powder
2 tsp baking soda
1 tsp salt
2 large eggs
1 cup (240ml) buttermilk
1 cup (240ml) vegetable oil
1 1/2 tsp vanilla
1 cup (240ml) water
1 1/4 cups (280g) butter
1 1/4 cups (237g) shortening
9 cups (1035g) powdered sugar
2 tsp vanilla extract
1 cup (114g) natural unsweetened cocoa powder (I used Hershey’s Special Dark)
4-5 tbsp (60-75ml) water/milk
6 oz (1 cup | 169g) semi sweet chocolate chips
1/2 cup heavy whipping cream
- Prepare three 8 inch cake pans with parchment paper circles in the bottom, and grease the sides. Preheat oven to 300°F (148°C).
- Add all dry ingredients to a large bowl and whisk together.
- Add eggs, buttermilk and vegetable oil to the dry ingredients and mix well.
- Add vanilla to boiling water and add to mixture. Mix well.
- Divide batter evenly between cakes pans and bake for 30-33 minutes, or until a toothpick comes out with a few crumbs.
- Remove cakes from oven and allow to cool for about 10 minutes, then remove to cooling racks to cool completely.
- Make frosting while cakes cool. Beat together butter and shortening until smooth.
- Slowly add 4 cups (460g) of powdered sugar and mix until smooth.
- Add vanilla and half of the water or milk and mix until smooth.
- Add another 5 cups (575g) of powdered sugar and mix until smooth.
- Add cocoa and mix until smooth.
- Add remaining water or milk until the frosting is the right consistency.
- Once cakes are cool, remove cake domes from top with a large serrated knife.
- Place first layer of cake on cake plate. Spread about 1 cup of frosting on top in an even layer.
- Add second layer of cake and add another cup of frosting on top in an even layer.
- Add final layer of cake on top and frost the outside of the cake. Feel free to use my tutorial for frosting a smooth cake.
- To make the chocolate ganache, add the chocolate chips to a medium sized bowl.
- Heat the heavy whipping cream just until it begins to boil, then pour it over the chocolate chips. Allow it to sit for 2-3 minutes, then whisk until smooth.
- Drizzle the chocolate ganache around the edge of the cake, then pour the remainder of the ganache on top of the cake and spread evenly. I like to use a squeeze bottle for drizzling around the edges.
- Allow the ganache to firm up a bit, then pipe the remainder of the frosting around the top edge of the cake and pipe a border around the bottom. I used Ateco tip 844.
- Add a few sprinkles to the cake, if desired, then serve. Cake is best when well covered for 3-4 days.
