Roll the pastry out, cut down the centre (lengthways) and lay 4 kinder bars down the edge of each strip. Cut the pastry between the kinder bars and roll each section from the outside in on both sides (you might want to watch the video for the laying/cutting/rolling!)

Turn the pastries upside down and place in the air fryer. Brush with egg (so they go golden brown when cooking) and air fry for 16 minutes at 180ºC.

Remove from the air fryer and let cool for 5-10 minutes. Once cooled, use a sieve to sprinkle over the icing sugar (don't eat whilst they're too hot as you'll scald your mouth!).
