You probably already have your own Peanut Butter Blossom recipe. If you don't, you can follow the one I did from Recipe Boy. It's a pretty standard recipe and was very good. After you mix the dough, form into 1 inch balls and roll in sugar. Bake as directed. When the cookies are done, top each one with a heart shaped chocolate candy (they use peanut butter filled hearts for their cookies), pushing down slightly. Pop the tray back into the oven for a few seconds. I don't even close the door because I'm always afraid I'll forget them!
After a few seconds in the oven to melt the candy into the cookies, let them cool on a wire rack. After the tray is cool, I put the tray in the freezer so the candy will set back up. If you don't, it will usually take a long time for the chocolate to get hard again.
Aren't they so cute for Valentine's Day????? I hear from my son's college roommate that they're delicious, too. :)
