Sift the cocoa powder beforehand through a fine sieve to avoid lumps.

Stir well on the bottom and along the edges to prevent sticking.

When the mixture briefly pulls away from the bottom of the pan while stirring, it's usually done.

Cover the surface directly with cling film to prevent a skin from forming.

If the mixture is too sticky, chill it briefly before continuing to shape.

Put the sprinkles in a small bowl and roll the balls in it to keep things tidy.

Let them sit at room temperature for 10 minutes before enjoying; they'll be especially soft then.
