I too made these candies and mine came out very soft also. I put the mix in the fridge to cool completely. I did butter my hands and manage to roll the very soft balls and then coat with nuts. However, they never became firm enough to hold their shape. I believe I didn't cook them long enough. I wonder if there is a certain temperature on the candy thermometer that it has to reach before removing from the heat source? Mine are currently frozen for Christmas, but would love to improve the texture. They are absolutely delicious.
