Love Oreos? Then you'll love this rich and fudgy Oreo brownies! The perfect brownie batter packed with pieces of Oreo cookies and topped with a creamy vanilla frosting.
Preheat oven to 350°F. Line an 8×8-inch baking pan with foil and spray with nonstick cooking spray.
Microwave chocolate and butter in a large bowl at medium (50% power) for 3-4 minutes or until butter is melted.
Whisk until chocolate is melted. Whisk in sugar until fully blended, then whisk in eggs one at a time, then vanilla and salt. Gradually add flour and stir until just combined. Fold in 12 chopped Oreo cookies.
Spread batter into prepared pan. Bake for 30 minutes; do not over bake.
Remove to cooling rack. Allow to cool completely before cutting or frosting.
For the Frosting
In the bowl of a stand mixer or in a large bowl with a hand mixer, cream butter until fluffy. Slowly add in confectioner’s sugar, and continue mixing until well blended.
Add salt, vanilla, and milk. Blend on low speed until moistened. If frosting is too stiff, slowly add in more milk until you reach the desired consistency. Beat at high speed until frosting is smooth and fluffy.
Spread or pipe frosting onto the brownies and top with chopped Oreo cookies.
