Using a bread knife, slice the bread into mini bite-sized pieces.

In a mixing bowl, whisk together 2 eggs and heavy whipping cream until fully combined.

Add ground cinnamon and granulated sugar to the egg mixture and whisk until smooth.

Dip the bread pieces into the custard mixture, ensuring each piece is well coated.

Heat a frying pan over medium heat and generously melt butter.

Fry the soaked bread bites, turning to cook all sides until golden and toasted.

In a small bowl, mix cinnamon and granulated sugar to prepare the cinnamon sugar coating.

Immediately coat the warm French toast bites with the cinnamon sugar mixture.

Warm Nutella separately for dipping.

Serve the French toast bites warm with Nutella on the side for dipping.
