Ingredients
For the cookies
2 cups all-purpose flour
1 cup plus 1 tablespoon unsweetened Dutch-process cocoa powder
2 teaspoons coarse salt
8 ounces (2 sticks) unsalted butter, softened
1 1/3 cups sugar, plus more for rolling
2 large egg yolks
2 tablespoons heavy cream
2 teaspoons pure vanilla extract
For the ganache
1/3 cup honey
1/3 cup heavy cream
1/2 vanilla bean, split and scraped, pod reserved
4 ounces bittersweet chocolate, finely chopped
1 ounce (2 tablespoons) unsalted butter, cut into pieces and softened
Directions
Preheat oven to 350F. Line your cookie sheets with silpat or parchment paper
Whisk flour, cocoa powder, and salt into a small bowl. Cream butter and sugar with a mixer until pale and fluffy. Reduce speed to medium, and add yolks, cream, and vanilla. Scrape sides of bowl. Beat in flour mixture until just combined.
Roll balls using 2 teaspoons dough for each, and roll each in sugar. Place 1 inch apart on cookie sheets. With the handle of a wooden spoon, press gently in the center of each to create an indentation. Bake until cookies are just set, about 10 minutes. If indentations lose definition, press centers again. Let cool slightly on baking sheets. Transfer cookies to wire racks, and let cool.
To make the ganche, combine honey, cream, and vanilla seeds and pod in a medium saucepan over medium heat. Bring to a simmer, and cook, stirring until honey dissolves. Remove from heat, cover, and let stand for 20 minutes.
Place chocolate in a food processor. Return cream mixture to a simmer, then strain through a fine sieve. Discard solids. Pour cream mixture over chocolate, and let stand for a few minutes. Process until smooth. Add butter, and continue to process, scraping down sides occasionally, until butter is incorporated. Let cool slightly.
Spoon warm ganache into center of each cookie. Let stand until firm, about 15-20 minutes.
