I do this exact recipe... except I do not even bake it. I use the Kraft boxed mac & cheese... when I drain it - immediately add about 1 large tablespoon of butter... the cheese packet. Blend... then add the shredded cheese. Because the cheese is still hot - everything melts together. I reheat - by putting into a bowl - top with a dollop of ketchup - little hot sauce - little chili sauce... Its great for something quick in middle of day. This is delicious - & something great to just grab & heat in middle of day. I do live alone... so the entire thing is mine to heat and nibble on... at will. Love it!
