Crunchy Layered Strawberry Tart

This is a lovely tart with a flapjack base, a creamy and subtle middle layer and a fruit top. It is simple and quick to make but tastes elaborate. It is best to make with fresh summer fruit on top but in winter you can use some good jam (warmed slightly to make it easy to spread) like black cherry or that delicious Hungarian apricot jam they sell in most supermarkets quite cheaply.
