Steps:

• Preheat oven to 450 degrees F (230 degrees C). Place pizza crust on a baking sheet.
• Bring a small pot of lightly salted water to a boil. Cook cavatappi in the boiling water, stirring occasionally, until cooked through but firm to the bite, 10 to 11 minutes. Drain and return pasta to the pot.
• Stir 1/2 the cheese sauce and butter into the cavatappi pot over medium heat until butter is melted and pasta-cheese mixture is combined. Season with salt and pepper.
• Spread a thin layer of cheese sauce over the pizza crust. Sprinkle shredded Cheddar cheese over the cheese sauce onto the crust. Pour pasta-cheese mixture over the Cheddar cheese, and top with another 1/2 the cheese sauce.
• Bake pizza in the preheated oven until golden and bubbling, 8 to 10 minutes. Let rest for 2 minutes before slicing.

Steps:

• To make the dough: In a bowl, dissolve yeast in warm water.
• In a mixing bowl, combine flour, oil, salt and sugar.
• Add in yeast water and mix together, making a ball.
• Knead by hand 5-10 minutes, until when you press your thumb down the indention stays. (You could also use your hand/stand mixer if it has a kneading attachment for about 2-3 minutes or you could use your bread machine).
• Rub small amount of olive oil around dough, to keep it from sticking, and place in a large bowl, covering with saran wrap.
• Place in a warm area to rise atleast 30 minutes.
• While the dough is rising, cook macaroni in boiling salted water until al dente.
• Drain and return to pan.
• Add in 1/3 jar of sauce and butter, stir.
• Set to the side.
• Preheat oven to 400°F.
• Roll out dough to fit either your pizza stone or out on a baking sheet, pinching up edges to make the crust.
• With a spoon, add a very thin layer of sauce on the dough and put in the oven to bake for 15 minutes or until dough is almost fully cooked.
• Remove from oven and add cooked macaroni; cover with more cheese sauce.
• Place back in the oven and continue to cook for an additional 10 minutes or until dough is fully cooked.
• Enjoy!
