Mexican Chocolate Butter Cookies
Why This Recipe Works
To cram big chocolate flavor into a tender, crisp chocolate butter cookie recipe, we found that cocoa powder—with a much higher percentage of cocoa solids than other forms of chocolate—was clearly the best candidate. So we doubled the amount of cocoa in our chocolate butter cookie recipe. Then we discovered that "blooming" the cocoa powder in melted butter (along with a teaspoon of instant espresso) before adding it to the dough really maximized the chocolate flavor.
