01 -  Preheat oven to 375°F. Grease a 12-cup muffin tin with olive oil or nonstick spray. 
 02 -  Bring a large pot of salted water to a boil. Add elbow macaroni and cook until al dente, 6 to 7 minutes. Drain and set aside. 
 03 -  In a large saucepan over medium heat, melt butter. Add flour and whisk constantly for 1 minute. Gradually pour in milk, whisking until smooth and thickened, 3 to 4 minutes. 
 04 -  Stir in shredded cheddar and mozzarella until melted. Season with salt and black pepper. 
 05 -  Add Alfredo sauce, minced garlic, and grated Parmesan to the cheese sauce. Mix until fully blended. 
 06 -  Fold cooked macaroni into the sauce, ensuring all pieces are coated. Stir in mini pepperoni, bell pepper, and black olives. 
 07 -  Unroll pizza dough and cut it into 12 equal squares. Press each square firmly into muffin cups, lining bottoms and sides. 
 08 -  Spoon the macaroni mixture into each dough-lined cup, filling nearly to the top. Sprinkle with extra mozzarella cheese. 
 09 -  Place muffin tin in oven and bake for 18 to 20 minutes, until dough is golden and tops are bubbling and lightly browned. 
 10 -  Let muffins cool for 5 minutes. Carefully remove from tin. Garnish with chopped basil or parsley and serve warm.
