- Make the sponge cakeBeat eggs and sugar until pale and fluffy. Fold in flour and vanilla gently. Bake in a lined pan at 180°C / 350°F for 20–25 minutes. Cool completely, then slice into a thin layer.
- Prepare pastry creamHeat milk with vanilla. In a bowl, whisk egg yolks, sugar, and cornstarch. Slowly add hot milk, then return to heat. Cook until thick. Cool fully.

Notes
Chill is key: Let the cake rest in the fridge for at least 4–6 hours, but overnight is even better. The layers set properly and the flavor improves.
Use cold cream: Whip the heavy cream straight from the fridge. It whips faster and holds its structure better when folded into the pastry cream.
Don’t rush the pastry cream: Cook it slowly over medium heat and keep whisking. If it turns lumpy, pass it through a sieve while warm.
Keep puff pastry crisp: Bake it fully until deep golden. If it feels soft, return it to the oven for a few more minutes. A crisp base makes all the difference.
Sponge cake should be light, not soaked: Brush it lightly with syrup. Too much liquid will make the layers collapse.
Level your layers: Trim puff pastry edges and sponge cake evenly before assembling. Clean layers give that classic bakery look.
Use a Rectangle Mold or cake ring if possible: It helps the layers stay straight and makes assembly much easier, especially for beginners.
