• Preheat the oven to 350 degrees F and place the racks in the upper and lower third of the oven.
• In a medium bowl, mix the peanut butter, sugar, and egg until well combined. Spoon 1 tablespoon of the mixture about 1 inch apart onto ungreased baking sheets.
• For standard PB cookies:

  Flatten the mounds with the tines of a fork, dipped in sugar, making a crosshatch pattern on the cookies.
• Make ‘em Festive!

  Roll the tablespoon of cookie dough in green or red sugar or sprinkles, then flatten with a fork.

Make it a peanut butter blossom:

• Roll the tablespoon of cookie dough in sugar of choice.
• Don’t flatten with fork.
• Follow baking instructions.
• Put a chocolate kiss on top as soon as they come out of the oven.

Bake

• Bake until golden around the edges, about 10 minutes, switching the position of the sheets halfway through baking. Transfer to racks to cool. Repeat with the remaining dough.
