Ingredients

  • 2 egg yolks
  • 30 g white sugar
  • 40 g corn starch
  • 400 g full cream milk
  • 1 whole egg for egg wash
  • 1 tbsp icing sugar optional, for dusting

Instructions

  • Prepare the ingredients: Separate 2 egg yolks from 2 eggs. Measure 30g white sugar, 40g corn starch and 400g full cream milk. Ensure all ingredients are measured before cooking.
  • Mix the custard base: In a saucepan (off the heat), whisk together 2 egg yolks, 30g white sugar and 40g corn starch until smooth. Gradually pour in 400g full cream milk while whisking to prevent lumps.
  • Cook until thick: Place the saucepan over low heat. Stir constantly for 2–3 minutes until the mixture thickens to a very thick custard consistency. Keep heat low and continue stirring to prevent scrambling. Turn off heat once thick.
  • Chill until firm: Pour the thick custard into a lined container. Smooth the surface evenly. Cover with cling wrap touching the surface and refrigerate for at least 6 hours or overnight until fully firm.
  • Cut into cubes: Remove the chilled custard and cut into evenly sized cubes.
  • Brush with egg wash: Crack 1 whole egg into a small bowl and whisk lightly. Brush each cube evenly with the whisked 1 whole egg. Place cubes in a single layer in the air fryer basket.
  • Air fry until golden: Air fry at 160°C for 15 minutes until golden on the outside. Allow to cool slightly before serving. Dust with 1 tbsp icing sugar if desired.

Notes

  • Flavour boost – Add 1/2 tsp vanilla extract to the custard mixture before cooking for extra flavour.
  • Spice kick – Add 1/4 tsp cinnamon to the sugar for a warm, subtle spice note.
  • Citrus twist – Add 1/2 tsp finely grated lemon zest to brighten the milk flavour.
  • Extra caramel finish – Sprinkle 1 tsp sugar over the cubes before air frying for a slightly caramelised top.
  • Oven option – Bake at 170°C (fan-forced) for 18–20 minutes if you don’t have an air fryer.
