4-Ingredient Peanut Butter Cookies

(left half are peanut butter cookies, right half has chocolate chip minis thrown in!)

I've had this recipe for years and years.  I must say, it is probably one of my favorite cookies to make.  Soft, chewy peanut butter cookies that I almost always have the ingredients for.  I mean, who doesn't usually have peanut butter, sugar, an egg and some vanilla laying around?   This time, I decided to mix it up and make another batch with some mini chocolate chips thrown in. So I guess those would be 5-ingredient cookies.    Super yum! 

They can come out a bit crumbly if you try to take them off the pan too soon.  But, that just means they are broken and must be eaten, right?!  That's my viewpoint, anyway.  =)

Ingredients:

1 cup peanut butter (can use creamy or chunky, based on your preference)
1 cup sugar
1 egg
1 teaspoon vanilla
handful or two of mini chocolate chips (optional)

Directions:

Preheat oven to 350*F.   Lightly spray a cookie pan with cooking spray.  
Mix all the ingredients together.  If using chocolate chips, mix the first 4 ingredients together, then stir in chocolate chips until you think you have enough (about 1/2 to 3/4 cup). 
Drop by rounded teaspoon onto prepared pan and lightly press down.
Bake for 5-7 minutes.  They will be super soft and puffy.  Let them sit for a few minutes and cool on the pan before trying to move.  I usually use 2 pans for these, and let one batch cool while the other cooks.
