Make custard sandwiches by spooning custard onto a slice of brioche, topping with another slice and pressing together
Let the sandwiches sit for 10 minutes so the custard soaks in
Whisk together the eggs, single cream, milk, sugar and cinnamon
Trim the crusts and cut each sandwich in half to make 2 sticks
Lightly air-fry the sticks to dry them out without browning
Melt butter in a pan over low-medium heat
Dunk each stick in the egg mixture and cook until golden, working in small batches
Place cooked sticks on a cooling rack
Sprinkle white sugar into a clean dry pan over low-medium heat and let it melt
Once golden, reduce heat and dip each stick to coat both sides using tongs or forks
Set on a rack to cool
Serve with extra vanilla custard for dipping
