Don't skip the greasing: Spraying your baking dish with nonstick spray ensures the bars don't stick and break apart when you try to remove them.
Work quickly: As soon as you take the melted marshmallow mixture out of the microwave, it starts to set, so work fast when pressing the mixture into your prepared pan.
No extra-large mixing bowl? Just make half the recipe and let the bars set, then make the other half and layer on top of a sheet of parchment paper on top of the first batch.
