For Cookie Dough:

1 cup unsalted butter (softened)

¾ cup brown sugar 

1/2 cup granulated sugar 

1 egg

2 tsp. vanilla extract 

2 cups all-purpose flour 

1 ¼ tsp. kosher salt

½ tsp. baking powder

¼ tsp. baking soda

1 cup semi-sweet chocolate chips

For Brownie:

3/4 cup unsalted butter (melted)

½ cup brown sugar (100g)

½ cup granulated sugar (100g)

2 tsp. vanilla extract 

2/3 cup cocoa powder (65g)

½ cup all-purpose flour (60g)

2 tsp coffee

½ tsp salt

½ tsp. baking powder

2 eggs

½ cup semi-sweet chocolate chips

Make the Cookie Dough:

1.Using a hand mixer, beat butter and sugars in a bowl until creamy, about 2 minutes. Beat in egg and vanilla until combined.

2. In a separate bowl, stir together flour, salt, baking powder, and baking soda. Gradually add flour mixture to butter mixture, beating on low speed until just combined.

3. Fold in both chocolates and oats until just combined (do not overbeat).

4. Divide dough in half; spread half of dough in an even layer in the bottom of a foil-lined, greased baking pan. Set pan aside while making brownie layer.

Make the Cookie Layer:

Place the Oreos on top of the cookie dough layer; breaking cookies to fit, as needed.

Make the Brownie Layer:

1. Preheat oven to 350°F. Mix the cocoa powder, flour and baking powder in a bowl then set aside.

2. In a medium bowl, beat together melted butter, sugars, eggs, and vanilla. Mix very well as this step gives you that nice brownie top.

3. Sift the dry mixture into the butter mixture; stir until no streaks remain then fold in the chocolate chips.

4. Pour brownie batter over Oreo layer; gently smooth top with an offset spatula.

5. Bake at 350° until a wooden pick inserted comes out mostly clean, 35 to 40 minutes.

6. For best slicing results, let cool completely, about 2 hours.
