This recipe leans on the convenience of boxed brownie mix (use your favorite fudgy style mix!)

However, any brand will work the same.

Just avoid using a brownie mix that has chocolate chips, as they become hard when chilled.

Scrape the brownie batter into the prepared pan and smooth into an even layer.

Bake the brownies according to the package directions for an 8-inch pan.

Sift the powdered sugar into the butter mixture.

Scrape the mint cream over the cooled brownies still in the pan and smooth into an even layer.

Let sit about 5 minutes to cool slightly.

If using, sprinkle the chopped chocolate mints over the ganache.

Return the brownies to the refrigerator until well chilled and firm, at least 30 minutes.

Transfer the slab of brownies using the overhanging parchment onto a cutting board.

Use a sharp knife to cut the brownies, wiping the knife clean between each cut.

For the best texture and flavor, serve the brownies chilled from the refrigerator.
