Ingredients Banana Custard Slices

500g Ready-Made Puff Pastry
375ml Milk
375ml Single Cream
60g Unsalted Butter
100g Sugar and Crumbs Banana Split Natural Flavoured Icing Sugar
50g Plain White Icing Sugar
50g Cornflour
125ml Water
6 Egg Yolks
A pinch of Nutmeg


* You’ll need a deep tray to set the Banana Custard Slices in. I use my square 23cm brownie tin which is perfect.

1. Preheat the oven to 190° C, 170°C fan, 350 F, Gas mark 4.

2. Cut the pastry block in half and on a floured work surface roll each piece out thinly so that it’s a few cms bigger than the tin you’re going to use.

3. Then line a couple of large baking trays with greaseproof paper and lay a piece of pastry out on each one. Place another baking tray on top of each and weight it down with baking beans (this is to stop it puffing up unevenly) and then pop in the oven for 30 minutes until crisp and golden.

4. Allow the pastry to cool in the tin for a few minutes, still weighted, and then transfer it to a wire rack to cool.

Next, make the custard

5. In a large saucepan measure out the milk, cream, butter, nutmeg, Sugar and Crumbs Banana Split Natural Flavoured Icing Sugar along with plain white icing sugar. Warm gently.

6. While that’s warming up separate the eggs (you don’t need the whites for this recipe – try using them in a meringue-like this) in a separate jug. Mix together the water and cornflour.

7. Once the butter has melted in the milk and cream, bring to the boil and then immediately remove from the heat. Add first the cornflour and then the egg yolks, whisking constantly as you add each ingredient. The custard may thicken up immediately but if it doesn’t, return it to a lower heat, still whisking constantly and you’ll find it thickens up within a minute or two.

8. Remove the custard from the heat and leave to cool while you prepare the pastry. Cut each sheet to size so it will fit snugly in the square tin. Line the tin with greaseproof paper and put one sheet of pastry in the bottom, then pour the custard in.

9. Lay the second sheet of pastry on top, pressing down gently so that the custard spreads out in a level layer.

10. Put in the fridge for about four hours to cool before cutting into slices with a sharp knife.
