Preheat the oven to 350 degrees. Line two pans with parchment paper.
Combine the oats, whole wheat flour, dark chocolate chunks, walnuts, raisins, baking powder, baking soda, and salt.
In a separate bowl, mix the butter, sugar and vanilla extract together.
Add the butter mixture to the oat mixture and mix until no flour remains.
Scoop the cookies into 1½ tablespoon balls. Place the balls three inches apart on the pan. Lightly press 1/2 teaspoon chopped candied ginger into each cookie.
Bake for 12 minutes, or until golden brown around the edges.
