Losing Fat + Building muscle at the same time?

So my question is, can I build muscle and lose weight at the same time? I’m 17 years old, 5ft4 and weight around 165 pounds as I’ve been bulking. I need around 3000calories to gain 0.5 pounds a week. I was wondering if I can eat this amount of calories and lose fat at the same time? I was going to do long distance walks to burn fat, I will eat 3000 calories+whatever I burn off from walking. Will this allow me to still build muscle as well as lose fat?

Thanks
