2cupspowdered sugar
2teaspoonsmilk
½teaspoonvanilla extract
4Oreosfinely crushed (for frosting)
4Oreoscrushed (for topping)
Instructions
Brownies:
Prepare brownie batter as instructed on the box. Pour into a pan and top the brownie batter with whole Oreos. I used about 16 Oreos for a 9x9 pan.
Bake the brownies as instructed on the box. Place on a wire rack to cool completely.
Frosting:
Beat butter and 1 cup of powdered sugar until combined. Add remaining powdered sugar, milk, vanilla, and a pinch of salt and beat until well combined. Adjust the consistency by adding more milk (to thin) or more powdered sugar (to thicken). Stir 4 finely crushed Oreos into the frosting.
Spread frosting on cooled brownies*, then immediately garnish with more crushed Oreos.
Notes
*You can spread the frosting on the whole pan of brownies, or you can cut the brownies first, then add the frosting to each individual piece.
