Mix the spices with the flour and sift one time to blend. Cream the butter and sugars until smooth. Add the egg and vanilla, mix well. Add the flour mixture and mix well. Fold in the oats and raisins blending them in.
Drop by heaping teaspoons or use smallest scoop, onto parchment lined baking sheets. Bake at 350 for 8 minutes, DO NOT overbake or they will be hard...for nice smooth chewy cookies, 8 minutes is all they cook, remove from oven, cool on sheet for two minutes then remove to cooling rack to finish cooling.
Note: Raisins may be plumped using water or juice...I use apple juice and brind to just a simmer in a boiler on the stove, remove from heat and let them set while I work on the batter, then squeeze the excess juice away and add to the batter.
