Chocolate Chip Cookie+Brownie+Oreo=SINFUL
If you want to impress your friends and family, or even strangers--make these. I've taken them to many parties and they are always a hit.
Chocolate Chip Cookie
  • ½ cup unsalted butter
  • ½ cup brown sugar
  • ½ cup granulated sugar
  • 1 egg
  • 1 teaspoon vanilla
  • 1¼ cup white flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
Oreo Layer
  • 12-18 Oreos
Chocolate Chip Cookie
  • 1 cup chocolate chips
  • 10 tablespoon unsalted butter
  • 1¼ cup granulated sugar
  • ¾ cup cocoa
  • ½ teaspoon salt
  • 2 teaspoon vanilla
  • 2 eggs
  • ¼ cup flour
Brownies Layer
  1. First, make the brownies. Melt the butter in a small saucepan over low heat. Once melted, add the sugar and cocoa. Remove from heat and add the vanilla, salt, and whisk in the egg. Fold in the flour and set aside.

  1. Next, make the chocolate chip cookie dough. Sift together the flour, salt, baking powder and baking soda. In a separate bowl, cream together the butter and sugars. Add the egg and vanilla. Add the chocolate chips. Mix just until combined.
  1. Now, preheat the oven to 350 degrees. Line a 9x9 baking pan with foil--making sure to leave a bit of overhang. This will make it super easy to pull the brownies out of the pan and leave you with one less pan to clean.
  2. Scoop the chocolate chip cookie dough into the bottom of the pan--pressing down to ensure an even coverage. You may have a little bit left over if you want to sample it.
  3. Open the Oreos. Eat one. Eat another one. Stop eating them. Make a nice layer of Oreos on top of the cookie dough. You don't need to get them super close together. You don't need to overlap them. Just a layer....don't stress so much about the details.
  4. Pour the brownie mixture on top of the Oreo layer. My brownie was a bit thick so I poured it on in glops and used a spatula to smooth it out. It worked wonderfully. You just want a nice even brownie layer over the top of the Oreo layer over the top of the chocolate chip cookie dough layer.
  5. Bake for 35-40 minutes. Check with a toothpick to ensure it is cooked all the way through.
  6. Let cool for 20 minutes before removing the foil from the pan. Cut into little squares and watch them be devoured quickly.
