Homemade Oreos

This recipe is from my friend Heidi. I first had them a couple years ago and I just had to get the recipe. They are so easy and tasty! When I made them this time I decided to try a peanut butter filling too. I make the cookies a little bigger than the recipe says. I do about a TBSP size ball and bake for 10 minutes.
