I subbed bourbon for pralines and creme liquor and didn't use nuts. It came out so good. If you find your mix too wet add more powdered sugar until you get a workable consistency.
I have been making these Bourbon Balls since it came out in S/L in 1981 ....they really are the BEST! I've made them for cookie exchanges and everyone wants the recipe. They are so easy to make esp if you have a food processor to mix all the ingredients..and then just shape into balls. These will always be made by me at Christmas time.
Like the previous reviewer, my family has been enjoying these every Christmas since 1981. I actually prefer them with rum, but I've also made them with Kahlua, Baily's and Cointreau. The nurses at the clinic where I work had fun one year administering breath alcohol tests--you'll actually fail the test during the first 15-20 seconds after eating one, due to the alcohol absorption by the mucus membranes lining the mouth. But no one gets tipsy! Also very pretty rolled in powdered cocoa or coconut. Very pretty for special occasions.
