In a large pot of salted water, cook tortellini according to package directions. Drain water.
Meanwhile, in a large non-stick skillet, add butter, heavy cream and cream cheese. Stir and simmer until butter and cream cheese has melted.
Stir in the Parmesan cheese and garlic powder. Turn heat to low and let simmer for 15 minutes or until thick and creamy.
Pour cooked, drained tortellini into skillet. Gently stir to coat pasta. Garnish with parsley, if desired. Enjoy!
