Add ⅙ tsp of cornstarch in the milk and stir until it dissolves properly.
Take a large microwave-safe mug. Put ½ cup of elbow pasta in the mug, then add ¾ cup of water, salt to taste, and 1 tsp of butter in it.
Microwave it until the water absorbs and the pasta is fully cooked. It takes about 4 minutes to get cooked completely. First, put the pasta in the microwave for 2 minutes and stir it. Then keep it in for 1 minute and stir again. Lastly, keep it for 1 more minute and stir.
1. Later, add ⅓ cup of milk in the mug and ½ cup grated cheese. Mix it well.

Your yummy and delicious mac and cheese is ready. Serve it hot and enjoy.
