Prepare the Cheesecake Filling by combining cream cheese, caster sugar, and vanilla extract, then fold in blueberries.

Slice the brioche loaf into 1.5-inch thick pieces and prepare them for stuffing.

Stuff each brioche slice with the cheesecake filling and seal the edges tightly.

Make the Custard Mixture by whisking together egg, milk, cream, and cinnamon.

Heat a skillet with unsalted butter and ensure it is hot and bubbly before frying.

Dip the stuffed brioche slices in the custard mixture and fry until golden brown on both sides.

Serve warm with icing sugar, maple syrup, and extra blueberries on top.
