Baking Challenge Week 26 (Late!) - Gluten Free - Three-Ingredient Cookies

'Tis the saddest cookie picture ever, I know.  But the recipe only makes twelve, and we did actually get all the way down to the last one before I realized there was no evidence I'd ever made them at all.

I've heard rave reviews about three-ingredient cookies in the past, how tasty and simple they are--and it's all true.

Three-Ingredient Cookies

• 1 cup crunchy peanut butter (smooth is okay too, but I like crunchy better)
• 1 cup sugar
• 1 egg 

Preheat the oven to 350 F. 

In a small bowl, mix all ingredients until smooth.  Drop heaping teaspoons of dough onto a baking sheet, two inches apart.*  Flatten the cookies slightly.

Bake 8-10 minutes, until dry on top and nearly set.  Allow to cool on the sheet for 1 minute before transferring to a wire rack to cool completely.

*My recipe specifies an ungreased sheet, but I found they stuck very badly.  They also sagged into the spaces in my wire rack, leaving dimpled bottoms.  Next time I intend to bake these on foil-lined sheets so I can lift the foil off to cool them all at once and avoid the misshapen bottoms.
