In a medium bowl, whisk together flour, cocoa powder, baking powder and salt; set aside.
In a large bowl, whisk together sugar, oil, and eggs until well mixed. Whisk in extracts.
Stir dry ingredients into wet ingredients just until combined. Cover bowl with plastic wrap and refrigerate for at least 2 hours.
Preheat oven to 350 degrees F. Line cookie sheets with parchment paper. Roll dough into ½ Tablespoon balls. Roll balls into mixture of powdered sugar/green sugar. Place on cookie sheets about 1½ inches apart. Bake for 11 to 13 minutes, until cookies crackle and dough doesn’t look raw.
While cookies are baking, unwrap the kisses and make some room in your refrigerator or freezer for the cookie sheets. When the cookies come out of the oven, immediately place a kiss in the center of each cookie and press lightly.
