Frequently Asked Questions

Why are they called Hello Dollies?
Hello Dollies became popular in the mid-1960s when the musical “Hello, Dolly!” was on Broadway. The bar cookies have several other names, including magic cookies or magic cookie bars, and seven-layer bars, because they typically have seven layers.
What’s the best way to cut a bar cookie?
The best way to cut a bar cookie is to wait until they have cooled completely, then cut them using a serrated knife. They are quite gooey, so if you really want to get a clean cut, try this method: Fill a tall, heatproof glass with boiling water and place the knife in it to heat the blade. Dry the knife and cut the bars. You may need to rewarm the knife blade in the hot water occasionally if the filling starts to stick to it.
Can I use a different type of chip instead of semisweet chocolate?
You can swap the semisweet chocolate chips for another flavor. We prefer the semisweet chips because this is already a sweet dessert and white chocolate or butterscotch chips will add even more sweetness. But feel free to experiment if you want to try another type of chocolate or chip.
