1cupunsweetened cocoa powder I prefer and use the Hershey's Dark Cocoa
2sticks salted butter melted and hot to the touch
1 1/2cupsgranulated sugar
1cuppacked brown sugar light or dark
1tablespoonpure vanilla extract
8whole Oreo Cookiesbroken in pieces
4whole Oreo Cookiesbroken in pieces
Preheat oven to 350 degrees F. and line an 9 x 13 inch baking dish with parchment paper.
Place flour, cocoa powder and salt in a large mixing bowl, stir to combine. Place hot melted butter, oil, and sugars into a large mixing bowl. Whisk until well combined, a good minute. Stir in eggs and vanilla, whisking another 2 minutes. Slowly stir wet ingredients into the dry ingredient bowl, gently stirring just until batter forms. Fold in Oreo Cookies and chocolate chips then transfer to baking dish. Spread evenly and top with 4 more Oreo Cookies, broken into pieces.
Bake for 25-27 minutes, until mostly baked through. If you want gooey brownies, remove at 25 minutes. Let bake longer for a more cooked brownie. Remove from oven and let cool for at least 1 hour before cutting into squares. Serve room temperature or warmed with a scoop of ice cream.
