In a large bowl, beat butter and brown sugar until crumbly, about 2 minutes. Add egg; beat well. Stir in flax and honey. In a small bowl, combine the oats, flour, cinnamon and baking soda; stir into creamed mixture just until blended. Gently stir in raisins. Press into an 11-in. x 7-in. baking dish coated with cooking spray. Bake at 350° for 14-18 minutes or until set and edges are lightly browned. Cool on a wire rack. Cut into bars.
