To make the crispy football, first line a tray (or plate that fits in the refrigerator) with baking paper.
Melt the milk chocolate coating slowly over steam. Mix the Choco Krispies with the chocolate. Place in football-shaped mounds on the baking paper. Refrigerate for about 30 minutes to allow the chocolate to set and bind the Choco Krispies together.
In the meantime, melt the white chocolate coating in a water bath. Pour into a baking paper piping bag (or other piping bag).
Remove the crispy footballs from the refrigerator and pipe the “seams” of the football with the white couverture. Let dry again and serve.
