Should I be putting my 15 month old daughter to bed earlier?

She goes to be at 8 pm every night.. but sleeps until like 11... by the time she is ready for a nap, it’s to late and then she’s just cranky all night.. I’ve put her to bed at 7 before and she STILL sleeps in late.. I’ve even tried waking her up earlier, like 8ish but she gets really... bitchy lol like not even cranky or fussy.. just mean, like don’t talk to me and walking around looking mad as hell.. I want to be able to just let her sleep but it’s messing with the rest of the day!
