What a brilliant idea! The preparation appears to be fairly straightforward, but you'll need an ice cream scoop to cover the oreos in chocolate chip cookie batter. Or your fingers.
got turned onto this recipe from another site (sorry dudes, but we never said we were going to be exclusive) and made them within 48 hours. they huge and awesome. i would advise sticking to the recipe, especially the cooking time, but let them cool for a good long while. you will have a semi soft cookie with a slightly firmer core. very, very yummy. unfortunately for me, i left them where i thought they would be safe from my very large dog and to put it simply, they were not. it sucked to lose all those great cookies. it really sucked to clean them up a day later.
