Oreo brownies are one of my most popular desserts. I am constantly asked to make these for friends, family, and coworkers…it’s always a crowd pleaser. It is a rich, dark, chocolaty brownie with Oreos throughout, and on top is melted chocolate and even more Oreos pressed into the chocolate. Sinful. But so worth it. 🙂
1/2 cup plus 1 tbsp. Hershey’s Cocoa Special Dark
¾ cup hot water
2 oz. unsweetened chocolate, chopped
5 tbsp. unsalted butter, melted
2/3 cup plus 1 tbsp. vegetable oil, divided
3 large eggs
1 large egg yolk
1 tbsp. vanilla extract
2 ¾ cups sugar
1 3/4 cups plus 2 tbsp.all-purpose flour
¾ tsp. salt
20 Oreos, divided
1 1/2 cups milk or semi-sweet chocolate chips, divided
1. Preheat oven to 350 degrees. Melt the butter in a saucepan and add the chopped unsweetened chocolate. Mix over low heat, stirring constantly, until chocolate is melted. Pour into a large bowl. Pour the hot water into the bowl and stir in the cocoa powder.
2. Pour 2/3 cup vegetable oil into the chocolate mixture and beat at low speed until combined. Add the eggs, egg yolk, and vanilla extract and beat for about 30 seconds. Add the sugar and beat until completely combined. Beat in the flour and salt. Crush 8 Oreos and stir into the brownie batter along with 1/2 cup of chocolate chips. Pour into a greased 13×9 in. pan and bake for approximately 35-45 minutes, or until a toothpick inserted in the center is almost clean, but still has a few chocolate bits. I like to undercook the brownies slightly, because they will continue to cook once they are removed from the oven.
3. Let the brownies cool. Microwave the remaining chocolate chips in a bowl for about 50 seconds. Stir in 1 tablespoon vegetable oil and continue to stir until it is completely melted (microwave for another 10-20 seconds if necessary). Pour over the brownies and spread out so the chocolate coats the entire surface. Crush the remainder of the Oreos, sprinkle over the top of the brownies, and press down so they adhere to the chocolate. Refrigerate for approximately 30 minutes, or until the chocolate is set but not hard
4. Cut the brownies and enjoy!
