Rinse and peel the potatoes.
Using a box grater with the side on the larger holes, grate the potatoes into a large bowl or on a plate, then squeeze out the liquid with a cheesecloth or using paper towel.
Repeat the same with the onion and add both the grated potato and onion to a large glass bowl.
Crack two eggs in a smaller bowl and whisk.
Pour the eggs into the potato and onion mixture, along with the garlic powder, salt, and flour.
Using a spatula, mix together the grated potato, onion, flour, garlic powder, salt, and egg until the flour is fully incorporated.
Taking a cookie scoop, scoop some of the potato pancake mixture and add to a large frying pan with oil over a medium heat.
Cook until golden brown on each side, approximately 3-4 minutes. Repeat until all the potato mixture is used.
