Preheat the oven to 180 degree celcius
Spray two 250ml coffee mugs (or small ramekins) lightly with cooking spray
Spread butter and jam onto the bread and sandwich. Cut into 2.5 cm pieces
In a small bowl, whisk together the eggs, milk, cream, sugar and spices
Add the bread to the bowl with the eggs and milk. Stir very well to combine
Divide the mixture between the mugs.
Sprinkle Demerara sugar over the top
Place the mugs on a small baking sheet, and bake for 25 minutes. The mixture will puff up and rise when you remove it from the oven.
Cool slightly. Pour over homemade custard.
Serve wrapped in a towel because the mugs are quite warm
