Burnt Sugar Layer Cake

The burnt sugar syrup can be made up to 1 week ahead and stored in an airtight container at room temperature. The cake layers can be baked 1 day ahead, wrapped tightly in plastic wrap, and stored at room temperature. Do not make the gelatin filling ahead—it must be prepared fresh and used immediately while still soft and spreadable.

Store the assembled cake in an airtight container in the refrigerator for up to 3 days. The gelatin filling will firm up when chilled. Bring to room temperature 30 minutes before serving for best texture. This cake does not freeze well due to the gelatin-based filling, which becomes weepy upon thawing.
