Mix the Ritz crackers, cheese, and salted butter in a blender for a quick & easy crust. Note: You can make this with regular yellow cheddar, but the white is wonderful. You can also mix it up by crushing and mixing by hand, but the blender makes it so easy!
In a saucepan over medium heat mix the remaining cheese, spices, beaten eggs, sour cream and cooked pasta until creamy, about 3 minutes.
Once you have a smooth consistency scoop into prepared muffin tins. You will have a little extra you can bake separately. Bake at 350 for 20 minutes.
Top with 1/2-1 cup additional shredded white cheddar cheese to gloss & moisten and put in the oven for an additional 5 minutes.
Cool slightly and used a knife to loosen crust from pan and it will pop out easily.
