I took these to church tonight. They were gone really fast. Someone told me they were delicious. I wished they made more in the batch. I will definetly double the recipe next time.
I used bittersweet chips instead and added liquer. I recommend chilling - I couldn't get them out of the muffin tin and the texture is much better after chilled.
I thought these were OK - but not great. I got a resounding 'so-so' by all of my 'guinea pigs'.
I'll definitely make these again. They're delicious and they sold well at our church bake sale. I left off the confectioner's sugar because I felt they were sweet enough and I was too lazy to deal with the mess of powdered sugar ;-) I used the first method with the 3-hour chill time. I may try the muffin tin method next time.
