Method
- Beat the soft butter and sugar with a mixer until fluffy, then whip in the eggs, yogurt, and vanilla.
- Divide the wet mixture in two, gently folding the sifted vanilla dry ingredients into one half and the chocolate dry ingredients into the other.
- Pipe the batters alternately into a prepared pan, drag a knife through in a zigzag pattern, and pipe a thin butter line on top.
- Bake at 347°F (175°C) for 45 minutes until a skewer comes out clean, then pour boiled sugar syrup over the warm sponge.
- Chill the cake for one hour, then pour the melted, tempered chocolate and hazelnut glaze over the top to set.

Notes
Avoid overmixing the two batters in the pan to ensure your final slices display distinct, clean layers rather than a muddy color.
