Do NOT try this at home...

ok...if you are on a diet...definitely don't make this!
I found a recipe (on a SUPER cool site - sugar plum for a brownie to DIE for! Make sure to stick them in the freezer for a little while before eating one. I know...that sounds crazy! Normally brownies are really only good right out of the oven - but trust me on this one...

Oreo Cream Cheese-Swirled Brownies (Recipe by Emiline from sugar plum)

Ingredients:
1/2 cup (1 stick) unsalted butter
3/4 cup granulated sugar
8 ounces (1 package) cream cheese, softened
3/4 cup confectioners' sugar
2 teaspoons vanilla extract
1 cup all purpose flour
1/2 cup unsweetened dark cocoa powder
1/2 teaspoon salt (scant)
2 large eggs
1 1/3 cups coarsely chopped Oreo cookies

Directions:
Preheat oven to 350 degrees F. Line an 8x8-inch square baking dish with foil; coat foil with cooking spray.

Melt the butter in a small saucepan, over medium heat. Whisk in sugar and bring to a boil, whisking frequently; boil 1 minute. Set aside to cool for 5 minutes.

In a small mixing bowl, using a mixer on medium speed, beat together cream cheese, confectioners' sugar and vanilla extract, until well combined, about 1 minute.

In a medium sized mixing bowl, sift together flour, cocoa powder and salt; whisk until combined.
In a large mixing bowl, whisk together eggs, until combined. Whisk in melted butter-sugar mixture until well combined. Stir in flour mixture until just combined, followed by Oreo cookies.

Spread half of brownie batter into baking dish, followed by cream cheese layer; dot the top with remaining brownie batter, and spread evenly, as best as you can. Run a knife through batter to make "swirls".
Bake at 350 degrees F, for 23-25 minutes. Cool on a wire rack to room temperature before slicing. Lift foil out of baking dish, and slice into 9 bars. For easier slicing, try freezing the brownies for 30-60 minutes.
