Cream the sugars and the margarine together. Add in your two eggs and beat in completely.
Add in the molasses to the margarine/sugar mix and mix in thoroughly.
Whisk together the dry ingredients.
Combine the wet and dry and mix well.Then add in your raisins.
Divide the dough into two pieces, and from each half form three long rolls on a cookie sheet.
Build them up as high as you can and they fit across a baking sheet, width-wise. When you build them up, you get a thicker, chewier bar.
Bake them in the oven at 375 for 13-15 minutes, and do not over/under bake. This from my grandma's instructions. So they need to be baked until the edges are cooked and the middle slightly still underdone.
Slice them across into about 8-10 squares when they are fully cooled, needless to say, this recipe makes a large amount, you can end up with 40-60 of the little bars!
