In a medium sized bowl, whisk eggs, milk and cinnamon together.
Slice the bread into 2-inch sections. Take a slice and make an opening in the bread with a paring knife that is about 1 inch deep. Stuff the slice of bread with 1 tablespoon of Nutella. Dip it generously into the egg and milk mixture, making sure to coat it on all sides.
In a buttered frying pan, cook the bread on medium-low heat until golden brown on each side. Make sure to cook it on the tops and bottoms, too, for a crispy edge.
Place on a plate and let it cool for about 30 seconds. Load up the inside with strawberries, and dust the top with powdered sugar. Serve with a glass of milk and enjoy!
