Bring a large pot of water to a boil and salt generously. Cut cherry tomatoes in quarters, and add them to your pan with olive oil on medium heat. Let them start to simmer, letting the juices run out in the pan.
Dice your garlic and add to the pan. Season with salt and pepper, and let it simmer on low for 10 minutes.
Add the penne to the boiling water. Let cook about 7 minutes, or until pasta is done to your liking. Before draining the water, save a mug-ful of pasta water and add it to your tomatoes. Swirl around until the tomatoes look "saucy".
Add the cream and fresh basil to the sauce. Add your penne to the sauce. Top with a mountain of parmesan cheese. Serve with some easy garlic bread and your favorite vino.
