Combine the sugar, flour, cocoa powder, baking powder, baking soda, and salt in a large bowl to begin making the cake recipe. Add the eggs, buttermilk, coffee, oil, and vanilla into the dry ingredients. Beat together on medium speed until thoroughly combined.

Heat the cream, then pour over the chopped chocolate and salt and let sit. Whisk until smooth and then refrigerate for 1 hour. Next, beat on medium-high speed until it becomes light and fluffy.

Feel free to add a few tablespoons of lemon juice to the Raspberry Filling for a citrusy kick.
