Cream butter and sugar, add 1 egg at a time then add milk. Now add crackers, mix well. Add nuts and raisins. Put in a tube cake pan. Bake 2 1/2 hours at 250 to 300 degrees or until done. (I bake it at 275 degrees for 1 1/2 hours and 1 hour at 300 degrees) cake will be soft on top when it comes out, but will be hard when it cools. Note: You can use 1 pound vanilla wafers instead of graham crackers. (Dot Williams makes hers this way.)
