Preheat the oven to the temperature specified on the croissant package or recipe (usually 350°F or 180°C).

Place the chocolate croissants on a baking sheet.

Heat them in the preheated oven for 5 - 7 minutes, or until they are warm and the chocolate inside is slightly melted.

Brew and prepare the coffee to your liking.

Serve the warm chocolate croissants with the coffee.
