Method

Preheat the oven to 350°F (177°C). Grease three 9-inch round cake pans, line with parchment paper, and grease the paper.
In a large bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder (if using).
In a separate bowl, use a mixer to combine the oil, eggs, sour cream, buttermilk, and vanilla extract until smooth.
Gradually add the wet ingredients into the dry ingredients. Pour in the hot water or coffee and mix until the batter is smooth.
Divide the batter evenly between the three prepared pans. Bake for 21-25 minutes, or until a toothpick comes out clean.
Remove cakes from the oven and cool in the pans on a wire rack. Let them cool completely before removing from the pans.
For the ganache, place chopped white chocolate in a bowl. Heat the cream in a small saucepan until it simmers, then pour over the chocolate. Stir until smooth and melted. Let cool in the fridge for 1-2 hours until spreadable.
For the frosting, beat the butter on high speed until creamy, about 2 minutes. Add the sugar, cocoa powder, milk, corn syrup, vanilla, and salt. Beat on low for 30 seconds, then on high for 2 minutes until smooth.
Place the first cake layer on a cake stand. Spread half of the white chocolate ganache on top. Add the second layer and spread the remaining ganache. Finish with the third layer.
Frost the top and sides of the cake with the chocolate silk frosting. garnish with fresh raspberries and mint if desired.
Refrigerate the cake for at least 45 minutes before slicing to ensure the layers set.
