not sure if this is what she is talking about but I make these

put peanut butter cookie dough into pan. bake as directed. once removed from oven, use tart shaper to make cups. place hershey kiss in center. let cool.

 

You could also do the reverse of this....put brownie batter in the muffin pan and bake as normal. use the tart shaper to make cups and place a mini peanut butter cup in each one!

I use frozen cookie dough (like the Nestle or Pillsbury which come in squares), cut the squares in half, stick each half in a muffin-cup, and then put a peanut-butter cup on top. The dough rises around the candy while it's baking, and they come out really yummy.

You can also do this with Rolos, or the Reese's with white chocolate (these look especially pretty).

 

I put a scoop of cookie dough in the mini muffin pan, bake then you use tart shaper when they come out. I then take some PB, a little dash of coco powder (baking kind) and some water, stir really well until smooth. Fill wells with this PB mixture and they are awesome! Just made it up because I wanted pb cookies and my kids wanted choc chip.
Enjoy!

 

WOW, what great ideas!!
