Melt chocolate in a large microwave-safe bowl on 50% power for 2 minutes. Let stand 5 minutes, then stir to finish melting. Return to microwave at 50% power for 30 seconds if needed. (Alternatively, melt chocolate in a heat-proof bowl over a saucepan of simmering water.)
Stir in remaining ingredients, using your hands if needed. Mound onto parchment-lined cookie sheets by heaping tablespoonfuls. Use an oiled cookie scoop or spoons (and dampened hands, if needed) to make it easier. Bake for 12-15 minutes, until just set (a few cracks, slightly matte in appearance but still very soft). Let cool completely on pan before trying to move - they will firm up as they sit.
