In a shallow bowl (big enough for your breadsticks to sit on the bottom of), whisk the eggs and milk together. In another shallow bowl, mix together the sugar and cinnamon. Set aside. Trim the crusts off the bread and then cut them into sticks, about 1 - 1.5 inches.
Heat up a bit of butter or oil in a non-stick pan over medium heat. Dip the bread sticks, one at a time in the egg mixture and place in the hot pan. Cook the dipped bread until golden, flipping so that all sides are cooked to a golden brown.
When the sticks are golden and cooked, dip immediately in the cinnamon sugar, coating all sides. Keep warm in the oven while you make the dipping sauce.
In a small heat proof bowl, heat the heavy cream in the microwave until warm. Stir in the chopped chocolate until smooth and melted. Alternately, place the cream in a small bowl over a double boiler and heat the cream and chocolate, stirring, until smooth and melted.
Enjoy the churro French toast sticks with the warm dark chocolate ganache dipping sauce.
