I did some research on the web today and according to lots of people, this is the recipe that comes closest to the original Cho Cho.
Cho Cho
(Recipe by Rich Creator)
1/2 gallon vanilla ice cream
3 tablespoons Carnation Chocolate Malted Milk powder
1 tablespoon Carnation Original Malted Milk powder
With a mixer, mix on high speed until creamy.
Pour into plastic drinking cups, insert a Popsicle stick, freeze.
(Note: Some recommend using 4 tablespoons of the chocolate malted milk powder instead of 3.)
I also miss Bonanzas and Cherryanzas but no way am I going to attempt to make those.
