You can also see this problem if your jacket collar/hood is blocking your exhalations, effectively bouncing them onto your facemask. Short of using a snorkel (actually there are some face masks that redirect your breath backwards, which I wouldn't want to wear with a hood), only solution is to open up the collar/hood further.
Differential diagnosis: is the fog on the outside or the inside of the mask? If your goggles are sitting on top of the mask as they should be, and your mask isn't vented, you'll get fog on the inside. The collar-bounce problem will make fog/ice on the outside.
You can also get fog on the inside just from evaporating sweat. solution: cool off: wear a lighter hat or unzip your jacket a little.
You can also try various soaps and waxes to make your goggles more hydrophobic, try double-lens goggles, try goggles with extra large vents. Most of the higher-end ski goggles have the latter two features, and ski shops will sell anti-fog balms. But if you're blowing hot breath onto cold goggles, you're going to have a problem.

has two triangular areas of breathing holes over the mouth area, to the left and right of a center seam. I cut two full triangles out where the holes are, leaving enough material to keep the seam intact. Start with a small triangle and enlarge it a little if it's not enough. Wear sunscreen lip balm.
