Mix brownie mix per instructions on the box (you’ll need those again so don’t recycle it just yet).
Pour into 9x9 greased square baking pan & place 8 generous dollops of frosting on top of batter.
Gently press & spread the frosting using the back of the spoon.
Run the edge of rubber spatula or knife through the batter to swirl it around the frosting (feel free to get creative!).
Bake according to the instructions on the brownie box.
