Start by bringing a large pot of salted water to a rolling boil. Carefully add the gnocchi and cook for 2-3 minutes or until they rise to the surface. Use a slotted spoon to remove the gnocchi, letting excess water drain off, and set aside.

In a medium saucepan, melt 2 tablespoons of butter over medium heat. Once melted, whisk in 2 tablespoons of flour, cooking for 1-2 minutes until it turns golden and bubbly. Gradually pour in 2 cups of whole milk, whisking continuously for 5-7 minutes until the mixture thickens into a smooth sauce.

Stir in 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and a pinch of salt and pepper. Lower the heat and gradually add in 2 cups of shredded cheese, mixing until completely melted and creamy.

In a large bowl, gently combine the cooked gnocchi with the cheese sauce, ensuring all pieces are well-coated. Preheat your oven to 350°F (175°C) and pour the mixture into a greased baking dish. For an extra cheesy touch, sprinkle additional cheese and breadcrumbs on top.

Bake for 20-25 minutes, until the top is golden brown and bubbly. Allow to cool for a few minutes before serving.
