Run the oats through a blender to turn them into flour. (Coarse is perfectly okay.) Whisk together with cocoa, baking soda, and salt in a small bowl. Set aside. In a larger bowl, cream butter, honey, and brown sugar. Add eggs and vanilla and beat well. Add dry ingredients, about a third at a time, beating well after each addition. Mix in chocolate chips, sunflower kernels, and flax.

Form into balls about 1 inch in diameter and place about an inch apart on an ungreased cookie sheet. Bake in preheated oven at 325 degrees F for 13 minutes. Let rest on cookie sheet until cool enough to transfer to a rack to cool completely.
