Molasses Cookie Beer

I'm thinking of making a brown ale with molasses, cinnamon, cloves, and ginger. I'm going to add a lot of it at the end of the boil to not loose the flavors and aromas. And maybe try my hand at some back sweetening with malto dextrine or other unfermentable sugar so I can still bottle condition.

Any suggestions or recipes would be appreciated. I'm thinking a northern English brown ale with earthy hops to not overpower.
