Preheat oven to 180’C

Make biscuit base. Cream the sugar and butter. Add muesli and mix. Then using a fork stir the flour into the mixture. Once it is mixed through press down into cake tin or pie dish. Bake for 30 minutes.

Make the custard. Heat the milk, butter and vanilla seeds. Careful not to burn. Reduce heat and keep stirring. Mix the flour, cornflour, sugar then add touch of milk until mixed through and runny. Add the eggs and whisk until all lumps are gone. When the milk has warmed up but not boiling add egg and flour mixture in and keep stirring. Reduce heat and keep stirring for 2 minutes.

Take pastry base out of the oven and pour thickened custard into base. Reduce oven to 160’C and bake tart until top of custard is slightly golden. Take out of the oven and let cool. Once cooled enough leave in the fridge for two hours. Then sprinkle cinnamon sugar over custard. The tart is best served cold.
