Individual Nutella Bread Pudding

Here is the first addition to the week's worth of Nutella breakfasts. This is a warm and decadent breakfast bread pudding. Throw it together the night before, then just pop it in the microwave in the morning and enjoy a warm breakfast in just a couple of minutes. You can make this as chocolaty as you wish, using as much Nutella as you would like. I don't really measure the ingredients, just eyeball them. If you make a really chocolaty version, feel free to enjoy it for dessert instead!

Individual Nutella Bread Pudding
4-6 slices white baguette (preferably not fresh), depending on size
hazelnuts
dark chocolate chips
1 large egg
1/2 cup milk
1 Tablespoon unsweetened cocoa powder
pinch ground cinnamon
1/4 cup Nutella

Tear the baguette into bite-sized pieces. Place in a mug and mix in as many hazelnuts and chocolate chips as you would like. 
In a small bowl, beat the egg, milk, cocoa, cinnamon, and half of the Nutella. Pour over bread. Refrigerate overnight.
To serve: top with remaining Nutella, then heat in the microwave on high (100% power) for about two minutes until firm and warm.
