The following kashrus information is from the COR Detroit dated December 27, 2013.
“DUNCAN HINES MILK CHOCOLATE BROWNIES, which in the past contained cream and milk and stated OU-D on 19.3 oz. boxes, has been reformulated to a pareve formula and now bears a plain OU on new 18 oz. packages. Each box should be carefully checked, because some old formula product is still on store shelves.
Many PILLSBURY FROSTINGS which used to be OU-D have now changed to plain OU (pareve) status, even some with names such as Milk Chocolate, Cream Cheese and Butter Cream. Each container should be checked, because some OU-D product is still on store shelves.”
