Blue Bell is always coming up with new add-ins. One of my long time favorites has been Pecan Pralines and Cream ummmmmm
mmmmm! That is so good.
Another has been Banana Split, which has all the ingredients for a banana split except whipped cream mixed in with the ice cream.
New this year (so far as I know) have been Coconut-Almond-Fudge, which really has large semi-sweet chocolate chips, not fudge in it, along with shredded coconut and chunks of toasted almonds, and Tres Leches Cake with Strawberries, both muy delicioso.
Okay, two of those have chocolate in 'em. Sorry.
A long time best seller has been their Peaches and Cream; I've never really cared for it and there's none this year, I understand, since the Hill Country peach crop was virtually nil because of bad weather.
