While the chicken and pasta are cooking, prepare the parmesan cream sauce. Begin by adding the 4 tbsp of butter and heavy whipping cream to a large skillet pan. Simmer over low heat for 2-3 minutes, stirring continuously to keep the cream from scorching. Add the minced garlic and pepper, and mix well. Add in the parmesan cheese, and heat until fully melted. Remove from heat, and set aside.
