I made the creamiest, melt-in-the-mouth Flan Cake

Refrigerate:
minimum 6 hours (ideally overnight)
This ensures:
✔ the flan sets properly
✔ the sponge cake becomes moist
✔ a PERFECT cut
RESULT
✔ Clean cut
✔ Firm and shiny flan
✔ Visible dulce de leche
✔ Fluffy sponge cake
✔ Professional homemade look
