Preheat the oven to 180°C (350°F) and line a baking tray with baking paper.
With an electric mixer, beat the softened butter until creamy and add the two sugars and cream together.
Add the eggs one at a time beating well in between. Add the vanilla extract.
In a separate bowl, mix the flour, salt and baking soda together.
Add the flour mixture to the wet ingredients in batches. The batter will be quite stiff.
Add the chocolate chips and stir in.
Divide the mixture into around 48 balls. Grab one ball and place it on top of an Oreo and grab another ball and place it underneath. Seal the edges together around the Oreo and place on the baking tray.
Bake for around 10 minutes. The dough will still be a little soft to the touch.
