I've never liked soda much, but I do enjoy root beer. Both the taste and the fact that it always seems a little old fashioned:
Add some vanilla ice cream and its even more delicious:
That is why when I saw the recipe for this pie in one of my favorite cook books First Prize Pies:
I new I had to give it a whirl. Technically it isn't a retro recipe, the book was published two years ago, but it's retro in spirit. I felt a little reluctant to put the recipe on here but its else where on the web and you really, really should buy the cook book. This is just one of the best desert cook books I've ever read and all the recipes are delicious. The author explains everything in detail and she comes up with great ideas, many of her pies are inspired by candy bars and other fun deserts like this pie.
The pie was pretty easy to make and it was fun too. The book gives recipes to make your own vanilla wafers and ginger snaps for the crust but I just used store bought ones.
