Preheat your oven to 350 degrees.
Prepare cavatappi pasta according to the directions on the box.
Melt 2 tablespoons butter over medium heat in a large saucepan or skillet big enough to hold the pasta.
Gradually whisk in flour until smooth; cook while constantly whisking for one minute or until thickened.
Slowly whisk milk and evaporated milk into the saucepan and cook until thickened.
Whisk Gouda, cream cheese, salt and a ¼ teaspoon of the red pepper flakes until smooth.
Remove from heat and stir in ham.
Pour pasta into the cheese sauce and mix.
Pour into a lightly grease 13 x 9-inch baking dish.
Stir 2 tablespoons melted butter and remaining 4 teaspoon red pepper flakes into the crushed corn flakes and sprinkle over the mac and cheese.
Bake at 350 for 45 minutes or until golden brown and bubbly.
Let stand for 5 minutes and then dig in!
