Millionaire's shortbread

The best recipe for this is from the queen Mary Berry


A variation is:

Put

• 225g plain flour
• 100g caster sugar
• 225g butter
  
• 100g semolina

into a food processor and 'pulse' until dough is formed.
Press mixture into a shallow tin and prick all over with a fork
Cook in pre-heated oven (160C) for about 30 minutes (until lightly golden)
Leave to cool

When cool, spread over a tin of 'Dulche de leche' or the toffee sauce in Mary Berry's recipe in the link above. (The latter is to gently heat together 175g butter, 175g sugar, 4tbsp golden syrup and 1 can of condensed milk.)

Melt 200g of good quality milk chocolate in a bowl in the microwave (see your microwave instruction booklet) or over a pan of hot water and spread over the caramel
