omrhill --- perhaps this will help you.
I think Pillsbury stopped making the dry frosting mix (coconut pecan and coconut almond) around 1971 or '72. However, that year one of the top winning recipes at the pbo used the product - and since it was not available every where they put this in after the recipe as a substitute if the dry mix could not be found:
"If frosting mix is not available, combine 1 cup coconut, 3/4 cup firmly packed brown sugar, 1/2 cup flour; cut in 1/2 cup butter or margarine."
I've used that mixture with success a few times over the years. Hope it will help you.
If Cate/Pillsbury or other Pillsbury is reading this .. I just spent about 30 minutes trying to find a previous request/posting - someone had requested the frosting (which was baked on the cookie) from the 20th PBO ... it used this dry mix. And I had responded to that query - about 1 to 1-1/2 months ago. It has completely disappeared. Do some posts with responses just go off into the atmosphere?
