Old School Vanilla Slice (snot block!)

I've adapted a recipe I found on Taste.com to suit the Thermomix, and as usual tweaked it a little.

First partially defrost 2 ready rolled puff pastry sheets, and line a baking tray with paper, lay out pastry sheetsop with more baking paper and weight with another baking tray. Bake at 200 degrees for 20 mins or until golden brown and crisp.

Add to the Thermomix bowl 1125g milk (I used skim it was fine), 250g sugar, 150g cornflour, 75g custard powder, 75g chopped butter, 2 egg yolks and 1 teaspoon vanilla extract. Cook 10 mins 90 degrees speed 4.

Once pastry is cooled a little, trim to fit the base of a 6cm deep 22cm square cake pan you have lined with paper including sides. Top with hot custard then trim the other sheet and fit to the top of the tin and custard. Cool for 30 mins.

Make icing by melting together 350g icing sugar, 15g butter and 100g passionfruit pulp at 90 degrees for 5 minutes speed 2. Top the layer of pastry with icing, and refrigerate for four hours. Serve sliced into squares. For fussy families (like mine!) make the icing vanilla instead I copped some resistance to the passionfruit!
