For National Mustard Day this Saturday, French’s is giving away mustard-flavored DONUTS. They’ll probably sell out fast, but boxes of two go on sale at DoughDoughnuts.com this Saturday (8/6) at exactly 9:00am. Each one is a classic glazed donut drizzled in, quote . . . a “savory yellow mustard coating” and topped with mustard cake crumbles. If you don’t get one, they also posted recipes online to make your own mustard donuts at home. Click HERE for the recipe.
