I first saw these at a bake sale and was so impressed. You bake a ball of dough in a mini-muffin tin, bake, and press a Reese's peanut butter cup into it after you take it out of oven. You are left with a picture-perfect tart, receiving "oohs and aahs" and "how did you do it?" You could even use the refrigerated sugar/peanut butter cookie dough too.
