best ever peanut butter cookies

So, I found this recipe on vanilla sugar the other day and had to try it out. It is fantastic! I have honestly never had such good peanut butter cookies. They were a little hard to form into cookies, but trust me, the results are worth it. These didn't last even 12 hours in my apartment.

1 cup all-natural chunky or smooth peanut butter (not too oily though, drain some oil out)
¾ cup dark brown sugar
¼ granulated sugar
1 egg
1 teaspoon baking soda
2 TB flour
1 ts sea salt
Bittersweet chocolate chips, about ½ cup, optional
Sea salt for sprinkling, optional

In a small bowl add the flour, baking soda and salt and mix, set aside.
In a mixer or by hand, combine peanut butter and sugars until well combined. Crack egg open in a small bowl and beat. Add egg to the cookie mixture; add in the flour mixture in several smaller increments. Mix until combined. Cover bowl and refrigerate until firm (vanilla sugar suggested 2 hours, but I only waited like 20 minutes and they tasted fine). Preheat oven to 350 degrees F. Roll into tablespoon sized balls and place on non-stick cookie sheets or greased cookie sheets. With a fork gently make a criss-cross pattern with a fork.
Bake for 10 minutes, until lightly browned. As soon as they come out of the oven sprinkle with just a bit of sea salt—this adds a nice peanut depth; this is optional.

If you want to add in a chocolate topping (which I did), don’t make a cross-cross pattern, but make a small well in the center. Bake half way (about 5 minutes) then add in ~4 chocolate chips and bake remaining 5 minutes or so. I also swirled the chocolate around so that it would be a smooth topping and not just chocolate chips on top. The chocolate was delicious, but the cookies were so rich that it was probably unnecessary.
Should make about 23 – 25 cookies.
