Preheat oven to 350°F and cover a cookie sheet with parchment paper.
In a large mixing bowl, combine all dry ingredients with a fork or whisk. In a separate bowl, combine all wet ingredients (everything left, except the blackberries).
Thoroughly combine the wet and dry ingredients. When batter is homogeneous, gently stir in blackberries and form the batter into balls evenly spaced on the parchment paper.
Bake for 18 - 20 minutes or until lightly browned.
