In a shallow bowl, mix together the eggs, milk, & vanilla extract. Sprinkle in the cinnamon. If needed, add more.

On medium heat, put the butter in the pan. Take 2 slices of bread & spread Nutella on one side & form a sandwich.

Take the sandwich, lay one side of the bread in the mixture. Immediately flip in the sandwich so the other side gets coated. Let the excess mixture drip off & place in the pan.

After 3 to 4 minutes, flip the sandwich. Cook until both sides are golden brown.

Repeat steps for the other sandwich.

Drizzle with desired syrup.
