Who can resist oreos, especially the cream center? And as a frosting on brownies its just as irresistable.
Make the brownies as directed on the package.
For the Oreo Frosting:
1/4 cup (1/2 stick) room-temperature, unsalted butter
1/4 cup vegetable shortening
2 cups sifted confectioners sugar
2 teaspoons vanilla extract
Place butter and shortening in a mixing bowl, and at low speed, mix together. Gradually beat in the sugar and vanilla. Turn the mixer on high and beat for 2 to 3 minutes until filling is light and fluffy.
Stir in desired amount of crushed oreos and spread on top of cooled brownies.
