Preheat oven to 425 degrees.
In a bowl mix the eggs, flour, salt, garlic powder and pepper.
Using a food processor or by hand, grate the potatoes and onions.
Wrap the potatoes in paper towels to drain liquid.
Mix the potatoes into the egg mixture and blend well.
Coat baking pans generously with cooking spray.
Drop a tablespoon at a time of batter onto baking pans (about 1 inch apart) and flatten each with a spatula. Place 20 pancakes on each pan.
Bake one tray at a time for 12-15 minutes until the bottoms are golden brown (use 2 ovens, if you have them).
Flip pancakes and bake 12 -15 more minutes until golden brown.
Place potato pancakes on a platter. Serve with sour cream and applesauce on the side.
Serve immediately or prep in advance and heat before serving.
