Cookie Dough Layer:
1 cup unsalted butter, softened
1 cup sugar
3/4 cup brown sugar
1 T pure vanilla extract
2 1/2 cups all purpose flour
1 tsp baking soda
1 tsp salt
2 cups semisweet chocolate chips
Preheat oven to 350 degrees. Spray a 9x13 baking pan with non-stick cooking spray, line with parchment paper leaving an overhang, and spray parchment paper with cooking spray. (You can never be too careful).
In a large stand mixer bowl, cream the butter, sugar, and brown sugar until light and fluffy, about 2 minutes. Add the eggs and vanilla and mix until incorporated. Add the flour, baking soda, and salt and mix just until combined. Stir in the chocolate chips.
Spread the cookie dough in an even layer by pressing into the bottom of prepared pan.
Oreo Cookie Layer:
1 package Double Stuf Oreo cookies
1/2 cup caramel sauce (I used Hershey's), or dulce du leche
Place the Oreos in a single layer over cookie dough. Drizzle with caramel sauce or dulce du leche sauce.
1 Box family size Brownie mix, plus ingredients to make (oil, eggs, water)
Follow directions on box to prepare brownie batter. Spread on top of Oreo cookie layer in an even layer using spatula.
Bake for 45-50 minutes. The brownies should look slightly gooey in the middle and will set up when cooling. Cool on wire rack for 20 minutes. Remove from pan by lifting the parchment paper out and cut into bars. Enjoy!
