How to Make It
In a bowl, using an electric mixer, beat the granulated sugar with the butter. Mix in the eggs, then add the cocoa and vanilla; beat at medium speed until smooth and creamy. Scrape down the bowl and add the flour, baking powder and salt. Mix the dough for 2 minutes. Stir in the chocolate chips and ginger. Cover the bowl with plastic wrap and refrigerate for at least 2 hours or overnight.
Preheat the oven to 350°. Line 2 baking sheets with parchment paper or foil. Form the dough into 1-inch balls and coat them generously with the confectioners' sugar. Arrange the balls 1 inch apart on the prepared baking sheets. Bake for about 12 minutes, or until the tops look cracked. Transfer to wire racks to cool.
