Bring a dutch oven or large, heavy pot of water to a boil and cook the tortellini according to the instructions on the package.
While the pasta is cooking, melt the butter in a large saucepan over medium-high heat and whisk in the garlic bouillon base and ground cinnamon. The butter sauce will begin to thicken and bubble as it cooks.
Add the chopped ham to the butter sauce.
Heat it through, browning the ham slightly on both sides.
Drain the tortellini, reserving ½ a cup of pasta water to use later.
Slowly add the pasta water and heavy cream to the saucepan with the ham and butter sauce. Cook for 3-4 minutes, stirring occasionally and de-glazing the bottom of the pan it cooks. Season with salt and pepper to taste.
Once the sauce has thickened, remove it from the heat and carefully and slowly add 1½ cups of finely grated parmesan cheese to the saucepan. Stir it in until it melts and it is all fully combined.
Add in the cooked tortellini and carefully toss to coat the pasta.
Sprinkle the remaining ½ cup of parmesan cheese and chopped parsley on top as garnish.
Serve warm and enjoy.
