It's the sarsaparilla root in the root beer that gives this cake its distinctive and delicious flavour.
This is a GREAT recipe!! You need to follow direction just right in order for it to come out, but it is WONDERFULL. The "Dessert Mix" is b box of Dream Whip" powder found in the jellow isle--it has 4 packets in it. - 05 Apr 2009 (Review from Allrecipes USA and Canada)
I was so excited to make it and when I did it was like the root beer flattened and setteled on the bottom and turned to glue. I made it for a Labor Day BBQ. Sorry, I didn't like it. The instant dessert topping is Dream Whip. You'll find it with the box pie crusts. - 06 Sep 2005 (Review from Allrecipes USA and Canada)
I did not yet make this but really want to, what is "instant desseret topping"? - 14 Nov 2001 (Review from Allrecipes USA and Canada)
