Let the potatoes cool for a few minutes, then peel off the skin and mash them in a mixing bowl.
Add the flour, salt, black pepper, garlic powder, and olive oil to the mixing bowl. Mix until a dough forms.
1 cup all-purpose flour, 1/2 tsp salt, 1/4 tsp black pepper, 1/4 tsp garlic powder, 2 tbsp olive oil
On a floured surface, roll the dough out into a long rope, about 1 inch in diameter.
Cut the rope into 1-inch pieces.
Bring a large pot of salted water to a boil. Add the gnocchi to the pot and cook for 2-3 minutes or until they float to the surface.
Use a slotted spoon to transfer the cooked gnocchi to a large mixing bowl.
