You’ll Need
Ready-rolled puff pastry
Ready-made vanilla custard (thick, chilled custard works best)
Optional but Encouraged
Icing sugar
Vanilla extract
White icing or fondant (if you’re committing fully)
Method
1 - Preheat your air fryer to 180°C for 3–5 minutes.
2 - Unroll the puff pastry and cut it into equal rectangles. You’ll need two per slice.
3 - Place the pastry rectangles into the air fryer basket, lined with baking paper.
4 - Air fry at 180°C for 8–10 minutes until puffed, golden, and fully crisp.
5 - Remove the pastry and allow it to cool completely. This matters — warm pastry melts custard.
6 - Once cooled, carefully slice the pastry horizontally if it’s puffed too high, or gently press it down.
7 - Spoon or pipe a thick layer of custard onto one pastry rectangle.
8 - Top with a second pastry rectangle and press down lightly to sandwich.
9 - Dust with icing sugar or drizzle with white icing if using. Serve chilled or at room temperature.
