Of course I found this on one of my favorite blogs, How Sweet It Is
The recipe follows, but please go check hers out as well!
Triple Layer Cookies and Cream Crunch Brownies
1 1/2 cups sugar
2 teaspoons vanilla extract
1 1/4 cups all purpose flour
1/4 teaspoon salt
3 tablespoons cocoa powder
2 cups chocolate chips
1/2 cup peanut butter
1/2 cup butter, at room temperature
20 Oreo cookies
Preheat oven to 350 degrees. Line a 9x9 cake pan with tin foil. Leave one inch overhangs for ease of moving. Spray the foil with Pam or other cooking spray.
In the bowl of an electric mixer, cream butter and sugar until fluffy. Add eggs one at a time, then add vanilla. Add in cocoa powder and mix until combined. Add flour and salt, mixing well until batter is smooth and comes together. Fold in 1/2 cup chocolate chips.
Spread the cake-like batter into the pan. Take 8 Oreos and cut them in half. Place cookie halves evenly and press slightly into the batter. This is so you may cut 16 brownies, and have an Oreo in the center of each. This can also be done with 9 whole Oreos if you only plan on making 9 instead of 16. Bake for 20-25 minutes. While baking, crush the remaining Oreos in a ziplock bag. When brownies are finished baking, remove from the oven and sprinkle with 1/2 cup chocolate chips and crush Oreos. Place back in the oven for about 2-3 minutes. Melt remaining chocolate chips and peanut butter together. Remove brownies from oven and pour melted chocolate mixture over top, spreading with a spatula. Spread evenly to ensure all squares will get a nice topping of chocolate. Place them in the refrigerator for 2 hours before cutting or serving. Remove brownies 15 minutes before cutting. This will make sure that the chocolate doesn't crack too much. Use the two overhanging pieces of foil to easily lift and transfer to a cutting plate.
Needless to say, there were no leftovers... I want another one.
