Peanut Butter Blossoms ~ they're the most popular Christmas cookie in America, and a beloved treat the rest of the year, too, so definitely don't save them for the holidays!
Preheat oven to 375F and line a baking sheet with parchment paper. Unwrap your Hershey's kisses and set them aside.
In a stand mixer or with electric beaters, combine the sugar, brown sugar, peanut butter, soft butter, and egg until smooth.
Add the flour, baking soda, baking powder, and salt, and mix to combine until no streaks of flour remain.
Scoop the dough into tablespoon sized portions and roll into round balls with your hands. Toss the balls in a small bowl of granulated sugar to coat evenly. Place on the prepared baking sheet, leaving about 2 inches of space between the cookies. Note: we found no benefit to chilling the dough, so we use it right away.
Bake for 8 minutes. The cookies will look puffed, and pale. Immediately, while the cookies are still hot on the baking tray, very gently press a Hershey's kiss into the center of each cookie. Note: it's important that you do this right away. Don't let the cookies cool, even for a minute.
Transfer the cookies to a cooling rack. Allow the cookies to fully set up before enjoying or storing them, as the chocolate kisses absorb the heat from the cookie and will be very soft while they are still warm.
Notes
As written, these cookies are fairly small: almost, but not quite, bite sized. I like the proportion of cookie to kiss. If you'd like to make them larger, that's fine, just add the extra baking time.
