HOUSTON -

The sweetest day of the year is here! Friday marks National Donut Day and there are a few places where you can score a tasty treat without paying a penny.

Swing by any participating Dunkin’ Donuts or Shipley Do-Nuts to grab a free glazed doughnut.

To get into the holiday spirit, Ruben Galvan went to the Shipley Do-Nuts in West Houston to find out more how the breakfast staple is made.
