COOK’S NOTES: If you bake the brownies in a 9 × 13-inch pan instead of the quarter sheet pan, they will be a little thinner and need a minute or two less in the oven. Trim the rectangles as needed to fit the loaf pan, as they will be slightly larger. To help soften and spread the ice cream, put half of it in a stand mixer and whip. Add the rest, whip again, and it will spread easily and evenly.
