1 six-pack hot cross buns, halved
2 cups fat-free milk
3 tbsp cocoa
3 tbsp artificial sweetener
100g dark chocolate grated (optional)
Preheat oven to 180*C. Lightly butter an ovenproof dish and line it with the buns in rows (in one or two layers, depending on size of dish). Mix cocoa powder with a little of the milk to make a paste; add this to milk and eggs, and beat gently to blend. Pour mixture over buns and allow them to soak up the liquid. Cover with grated chocolate. Place in the preheated oven until custard has just set (about 20 to 30 minutes).
