1/2 cup brown sugar
1 cup whole wheat pastry flour
1/4 cup crystallized ginger (I used a little less since I did not top all cookies with ginger)
Preheat oven to 350 degrees.
Cream butter and sugar with electric mixer until smooth and creamy, about 3 minutes. Add minced ginger, ground ginger, cocoa, vanilla, flour, baking soda and salt. Mix until dough comes together.
Roll out the dough on a lightly floured surface (I used powder sugar on the surface). Cut out cookies and push a small piece of crystallized ginger into the center of the cookie.
Bake on parchment pager until the edges are lightly golden, about 10-12 minutes. Remove from oven and cool on rack.
