Cookies and brownies have been dessert staples in America for years, with their sweet, chocolatey flavors captivating and stealing the hearts of Americans. But what people do not know is that when these two staples are mixed, it creates a dessert that is just as good, if not better. Cookie brownies, also called “Crownies” or “Brookies” for short, are just what they sound like – a mixture between cookies and brownies. Crownies combine that sweetness of a chocolate chip cookie with the richness of the brownieThese sweet treats are simple to make, only taking an hour or so to make a full batch.

  1. Alternate dolloping large spoonfuls of cookie dough and brownie batter into baking dish. Use a knife to swirl through both doughs and make sure the batter is in an even layer. 
  2. Transfer to 350F (175C) oven and bake for 35-40 minutes or until a toothpick inserted in the center comes out with a few moist crumbs or clean (make sure you are not sticking the toothpick into a chocolate chip!).
