Ingredients
Method
- Line baking trays with parchment paper and lightly dust them with powdered sugar.
- Place each puff pastry sheet flat on the tray and prick the surface with a fork — this keeps them from puffing up too much while baking.
- Cover with another sheet of parchment paper and place a second baking tray on top to keep them flat.
- Bake for about 12–15 minutes, until golden and crisp. Let them cool completely, then trim the edges so all sheets are the same size.
- In a medium saucepan, heat the milk over medium heat until it’s warm but not boiling. In a separate bowl, whisk together the egg yolks, sugar, cornstarch, and flour until smooth.
- Slowly pour half of the warm milk into this mixture while whisking constantly.
- Pour the mixture back into the saucepan with the rest of the milk. Continue stirring over medium heat until it thickens to a pudding-like texture — about 6–8 minutes.
- Remove from heat, stir in vanilla, and let it cool for 10 minutes. Then, whisk in the softened butter until creamy and glossy.
Assemble the Layers
- Place one baked pastry sheet on a serving board or tray.
- Spread about one-third of the custard over the top. Repeat with the second layer and more custard, then top with the final pastry sheet. Press gently to level it out.
- Refrigerate the assembled cake for at least 6 hours, or overnight if possible.
