Preheat oven to 375 degrees Fahrenheit. Grease a 9x13 inch baking dish with cooking spray or butter.

In a large bowl, combine ricotta cheese, 1 cup mozzarella cheese, parmesan cheese, beaten eggs, garlic powder, Italian seasoning, and fresh basil. Mix until well combined.

Spread 1 cup of marinara sauce on the bottom of the prepared baking dish. Arrange 12 frozen dumplings in a single layer over the sauce.

Spread half of the ricotta cheese mixture evenly over the dumplings. Top with 1 cup of marinara sauce and sprinkle with 1 cup of mozzarella cheese.

Arrange the remaining 12 dumplings over the cheese layer. Spread the remaining ricotta mixture on top, then cover with the remaining marinara sauce.

Cover the baking dish tightly with aluminum foil. Bake for 35 minutes. Remove foil, sprinkle with remaining 1 cup mozzarella cheese, and bake uncovered for an additional 10 minutes until cheese is melted and bubbly.

Remove from oven and let stand for 10 minutes before slicing. Garnish with additional fresh basil if desired and serve hot.
