Chocolate Chip Cookie & Oreo Brownies

If I had to choose my favourite brownie recipe, out of my entire collection - and there are hundreds - then this would be it. A chocolate chip cookie base is topped with whole oreos and luscious brownie. The oreos soften in the oven, creating one-third of the deliciousness, along with the rich, fudgy chocolate brownie and the crunchy, chocolate-laden cookie base. The ultimate brownie variation; a work of genius. Yum. I can't even express how much I love these brownies.

Brownie Layer

140g unsalted butter
1 1/4 cups sugar
3/4 cup cocoa powder
1/2 tsp salt
2 tsp vanilla
2 eggs
1/2 cup plain flour

Oreo Layer
2 rolls (one pack) Oreos

Cookie Dough Layer
1/2 cup (115g) unsalted butter
1/4 cup brown sugar
3/4 cup sugar
1 egg
1 tsp vanilla
1 1/4 cup plain flour
1/2 tsp salt
1/2 tsp baking soda
1/2 tsp baking powder
1 cup chocolate chips

Line a 9x9 inch pan with baking paper. Preheat the oven to 180C. 

Make the brownie layer: 

In a saucepan melt the butter over a medium heat. Whisk in the sugar and cocoa powder. Add the salt, vanilla, eggs and whisk until combined. Gently fold in the flour. Set aside.

Make the cookie dough layer: 

In a large bowl cream the butter and sugar together on medium speed. Add the eggs and vanilla and mix until combined. Fold in the flour, salt, baking soda and baking powder, followed by the chocolate chips.

Press all the cookie dough into the bottom of the pan. Place as many oreos as possible on top of the cookie dough without putting any on top of the other. Spread the brownie batter over the oreos. Bake for 30-35 minutes or until only fudgy crumbs come out on a toothpick inserted in the centre. Enjoy!
