Oreo Stuffed Choc Chip Biscuits

Whats thick and chewy, speckled with chocolate chips and has an oreo hidden inside?
These big beauties. Just wait until everyone sinks their teeth into these super man sized biscuits and exclaims in surprise at the dark, rich and chocolatey oreo hidden beneath the golden outer layer of choc chip biscuit. You might imagine all this biscuit plus an oreo in the centre would be going overboard, and perhaps too sweet to truly relish. But in reality, this biscuit stuffed in a biscuit is perfectly balanced. The chocolate chip biscuit is simple and plain, and the oreo-well we all know the oreo-it has a reputation for being dark, rich and handsome-something most people can't deny there's a strong attraction about.
Then again, I am a huge sweet tooth, and some people might find this biscuit overbearing. Do not let it put you off creating it! I have seen mini oreos for sale, and these would make for a great substitute for the regular sized ones, as there wouldn't be so much biscuit in one serve.
However if you're more full on like me, you will relish the rare opportunity to wolf down this giant cookie with your next mug of coffee. Be warned--you may just have to skip lunch!

OREO STUFFED CHOC CHIP BISCUITS (Adapted from Picky Palate)

1 cup butter, softened
3/4 cup brown sugar, packed
1 cup granulated sugar
2 large eggs
1 tbsp. pure vanilla
3 1/2 plain flour
1 tsp salt
1 tsp baking soda (or bicarb soda)
1 1/2 cups choc chips (small ones)
2 boxes of oreos (or approximately 24 biscuits in total)

Preheat the oven to 175C.
Beat the butter with the sugars in a large bowl until well combined. Then add the eggs and the vanilla and mix until well incorporated. Sift the flour, salt and baking soda into a separate bowl and combine. Add the chocolate chips. Gradually add this dry mixture to the wet mixture until just combined.
Take approximately one heaped tablespoon of the dough and place on the top of an oreo biscuit. Take another similar sized scoop of the mixture and place it one the bottom of the oreo. Merge the sides so that the dough completely covers the oreo, and your oreo is roughly in the centre of the dough. You can remove excess cookie dough from the top and bottom if it's looking too massive.
Place on a lined cookie tray and bake for approximately 10 minutes or until they begin to turn slightly golden at the corners. Cool on the tray for 5 minutes before removing to a wire rack.
