Pet d’ange. You could also call them chi-chi Mallomars. Recipe from Peter Greweling’s Chocolates and Confections
Golden brown shortbread rounds, about 1.25 inches each.
Globs of too-loose marshmallow lounge on the shortbread rounds, threatening to eclipse them altogether.
Cross-section close-up of “pet d’ange.” With shortbread and without. And yes, that is chocolate bloom on the chocolate disks used in the non-cookie version.
