Try them with Mini Reese's peanut butter cups instead of kisses. They are WAAAAYYY better. Also I found the secret on doing them with kisses. First make sure you have the kisses unwrapped prior to pulling the cookies out of the oven. Second put the kiss in unside down - top in first. I did them the other way and found they would fall out.
Do you use mini muffin tins to make these or just make them on a cookie sheet? Mini muffin tins work best.
When I make Nicole's Reese's Peanut Butter treats for Christmas parties or for our recital luncheon, they always go.
If someone wants the reciepe I have, just send me a private note and I will give it too you.
