Pre-heat your oven to 350 degrees F. Line a 9x9 baking pan with tin foil and spray with non-stick baking spray.

In a large saucepan over medium high heat, melt the butter.

Once the butter has melted, add the white sugar and cocoa powder. Stir to combine and remove from the heat.

Add the salt, vanilla and eggs, whisking until fully incorporated.

Add in the flour, chocolate chips and half of the crushed oreo cookies and stir until just combined.

Scoop the batter into the prepared baking pan. Sprinkle the remaining oreo cookies on top.

Place the pan into the oven and bake for about 25-30 minutes. Remove the pan from the oven and let the cookie and cream brownies cool for at least 2 hours.

Remove the brownies from the pan by lifting the tin foil out. Place the brownies on the counter, cut into 12 squares and serve.
