Cut your brioche into 6cm thick slices.
Whisk the eggs, cream, vanilla and sugar in a large flat bowl.
Heat the butter in a flat frypan over a medium high heat.
Dip the bread in the egg mixture, making sure you are coating all sides well.
Fry in the heated pan, adding butter as needed, until golden on the outside and the egg is all completely cooked.
Serve immediately with loads of blueberries and cardamom maple syrup.
To make the syrup, just stir the cardamom oil through the syrup, being cautious not to overdo it as the taste can be quite overwhelming. Syrup will intensify in flavour as it is kept longer, so always err on the side of not enough cardamom oil.
