1box of Betty Crocker’s chocolate fudge brownie mix
Preheat the oven to 170˚ C. Line a baking tin with baking parchment and grease it.Melt the butter and let it cool. Put the brown and white sugar into a bowl, pour the cooled melted butter over and beat together. Beat in the vanilla, the cold egg and egg yolk until the mixture becomes light and creamy.
Then slowly mix in the flour and bicarbonate of soda until just blended. Finally fold in the chocolate chips.
Spread the cookie dough in the bottom of a lined baking tin.
Top with a layer of double stuffed Oreos.
Mix together brownie mix, adding an optional 80 grams of fudge topping to the mix. Pour the brownie batter over the cookie dough and Oreos.
Cover with foil and bake at 170˚ C for 30 minutes. Remove the foil and continue baking for an additional 15-25 minutes. Remove from the oven and let it cool completely before cutting. The brownies may still be gooey in the middle when still warm, but will set perfectly once cooled. Enjoy!
Feel free to use a pre-made cookie dough mix to make this even easier!
