Our today's recipe is devoted to furious chocolate fans. Very chocolate cookies with a little surprise: there is no gram of flour in the composition. Crumbly structure, bright taste, long time (up to 2 months of storage in a closed container) taste qualities are preserved – these indisputable advantages will not let this recipe pass by your selective attention. Let's talk about the ingredients. You can use any chocolate, but truly bitter chocolate, with a high content of cocoa in the composition (we have 72%), makes the taste delicious and very chocolate. Choose high quality butter (82.5%) in order not to spoil the chocolate emulsion during the cooking process. Cocoa powder should be without fillers, and it is better to use corn starch (in order to avoid a light taste when using potato analogue).
