How to eat a calorie surplus without getting fat?

I've been doing a lot of reading and research on how to eat to gain muscle. So far what I've gathered is that I need to be eating a calorie surplus and lots of protein.

How do I properly eat a calorie surplus without gaining weight in my stomach (I gain weight there easily.)

I'm trying to build my glutes but don't want to get a belly while doing that.

Any suggestions/tips are appreciated.
