Take a pot of water and boil some macaroni until it is slightly tender. Drain the water and put the macaroni to the side.
In a saucepan, melt the butter, then stir in the flour, whisking for about one minute.
Gradually incorporate milk and cream. Whisk for about 5 minutes or until thickened.
Add the cheeses, smoked paprika, mustard, salt, and pepper and mix until even.
In a 9x13 dish, combine the pasta and cheese sauce.
Mix the panko with olive oil, then spread on top.
Bake until it's golden and bubbly. That's usually about 20-25 minutes at 375°.
