Cook the penne pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Stir in the crushed tomatoes, dried basil, sugar, salt, and black pepper. Bring to a simmer and cook for 5 minutes, stirring occasionally.
Reduce the heat to low and slowly stir in the heavy cream. Cook for an additional 2-3 minutes until heated through.
Add the cooked penne pasta to the skillet and toss to coat the pasta evenly with the sauce.
Stir in the grated Parmesan cheese until melted and well combined.
Serve immediately, garnished with fresh basil leaves.
