Place a large pot of water over high heat. Once it comes to a boil, cook the pasta according to package directions and drain it. Return the drained pasta to the pot and set it aside.

While waiting on the water to boil, in a large, deep skillet, heat the 1 tbsp. butter over med-high heat. Once it's melted, add the shrimp. Season it with 1 tsp. of the cajun seasoning and cook until it is pink and opaque. Remove it to a plate, cover the shrimp with foil and set it aside.

Place the cream, the 1/2 cup butter and the cream cheese into the same skillet. Whisk it together often while it all melts.

Once the butter and cream cheese are melted and smooth, whisk in the remaining 2 tsp of cajun seasoning, the pepper, the onion powder, the garlic, the tomatoes, the parmesan and the gouda. Whisk until the cheese melts completely.

Allow the sauce to simmer for 5 or so minutes, to thicken up. Then combine the sauce and the shrimp with the pasta in the pot. Toss everything together until it's all incorporated.

Serve immediately and enjoy. Refrigerate any leftovers.
