Candy Glass Preparation
- Line a baking sheet with parchment paper. In a saucepan, combine granulated sugar, light corn syrup, water, and cream of tartar. Heat until it boils and reaches 300ºF. Pour onto the baking sheet and cool completely before breaking into shards.
Cake Preparation
- Preheat the oven to 350ºF. Line four 6-inch round cake pans with parchment paper and spray with cooking spray.
- In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
- In another bowl, cream unsalted butter with granulated sugar and brown sugar until fluffy. Add eggs one at a time, then sour cream, vanilla, and vinegar.
- Gradually add buttermilk and dry ingredients alternately until just combined. Divide batter among pans and bake for 25-27 minutes.
- Cool cakes in pans for 10 minutes, then transfer to wire racks.
Buttercream Preparation
- Create a double boiler and whisk egg whites with sugar and salt until 160ºF. Whip until fluffy and cool, then gradually add cold butter.
Ganache Preparation
- Gently heat white chocolate and heavy cream in a saucepan until smooth. Mix in drops of red and black food coloring.
Cake Assembly
- Layer the cakes with buttercream, sprinkle with dark chocolate, and chill for 30 minutes. Apply a thin crumb coat, followed by a thicker final layer of buttercream.
- Drizzle ganache over the top and garnish with candy glass shards.

Notes
Ensure the candy glass cools completely before breaking. Use gel food coloring for a rich hue. Check oven temperature for accuracy.
