Preheat oven to 350°F.

Line the bottom and sides of a 9 by 9 inch square baking pan with parchment paper.

Follow the instructions on the cookie mix box and stir furiously until you have gooey cookie dough, I generally add an additional teaspoon of water and oil to keep the dough moist as you will be baking it for longer than proposed.

Press the cookie dough into the prepared baking pan, until it covers the bottom.

Cover this layer with a single layer Oreos. Don’t use the broken ones, eat them as you go. This recipe is too wonderful to use substandard Oreos.

Mix up your brownie batter according to the recipe on the box and pour over the Oreo layer.

Bake 30 minutes.

Remove from the oven and funky.

When still a little bit warm, use the paper to lift your creation out of the pan and rest it on a chopping board.

Use a large, sharp knife to cut it into manageable chunks, sections, slabs, depending on how many calories you think you can handle in one sitting, usually 16 squares.

Serve with a scoop of your favourite ice cream, if desired.
