Oven baked French Toast

I love french Toast.. On a lazy sunday morning.... A good cup of tea... Some good book... This recipe for french Toast is genious as it is baken in the oven and meanwhile you can prepare the rest of your lazy sunday breakfast. I found the recipe in a cookbook from Donna Hay. I adapted it only a little by changing the used milk and reducing the number of eggs and using some brioche.
You neeed: (serves 2 - 4)
4 Brioche slices (rest of a brioche)
1 big egg
250 ml soy milk
1/2 tsp. ground cinnamon

Some vanilla essence (or vanilla sugar)
2 tbsp. Agave syrup
Some salt, a little bit melt butter (for the baking dish), some maple syrup
To prepare:
1. Cover your baking dish with some parchment paper or baking foil and brusch with some melted butter.
2. Put the brioche slices int the buttered dish.
3. Mix together milk, cinnamon, sugar, milk, vanilla, a pinch salt and pour over the brioche.
4. Wait for about 20 minutes and then put in the to 180C preheated oven and bake for about 25 minutes until golden brown and crispy.
5. Serve with some powder sugar and maple syrup
