I don't know if it is otherwise similar, but "Jordan Marsh Blueberry Muffins" call for half mashed and half whole blueberries, in a simple batter with flour, sugar, butter and milk. You can find it on many sites if you google that title. In our house they are known as "Great Grandma Mary's blueberry muffins" as she always had them warm out of the oven for grand kids and great grand kids on arrival.
