Maple-Spice Cookie Squares with Mayonnaise Icing

The one in the picture was baked in a slightly smaller dish than the recommended 9" x 13" so it's a little thicker. These generally will make a thinner, more cookie like square.

Very nice to have a couple with a hot cup of coffee or tea on a frosty morning, or as an afternoon pick-me-up.
