Broken toilet flange help

Noticed a small leak around our downstairs toilet. Bought a replacement ring and figured I could do it myself.
Pulled the toilet, scraped the old wax, and noticed the plastic flange is broken. Instead of cutting that pvc closet flange out completely, can I just purchase a metal ring and bolt down on top of the broken plastic one?

No idea, but I'm interested to hear the DIY for this.
Is the house on a slab?

They sell inserts for uneven issues how ever it will change the depth.

Me and a buddy just did this same thing at my house last wk. The plastic rail around both bolts were broke. Called my buddy, who is a plumber, for advice on removing the flange. He came over and put a couple of the small, metal closet flange repair pieces over the old flange and put tapcons into the concrete to hold it. Very simple fix, embarrassed I called him.

If you have a Sawzall it's pretty easy to replace the old one. Stuff a rag in the pipe and make about 6 cuts inside the flange but not all the way thru to the pipe. Then take a chisel and break pieces out. Clean it up and glue a new one in.

Maybe I don’t even really need to worry about it since the original plastic flange is still sturdy. I might be ok with just sticking a new ring on top and calling it a day?
ETA: nvm on that thought, since the plastic piece that is broken would hold the toilet bolt.

Though the proper way to repair is to do as rooster108 described and cut the flange out, I used this metal repair flange by Danco - buy at Home Depot. There are several Y/T videos on installing. One to get you started LINK.
It will be rock solid. I assume that is a concrete floor, so you need to drill holes with a concrete drill bit, and then use Tapcon concrete screw to anchor it to the floor.

I bought one of these years ago just so I would have to deal with this misery the hard way again.

Slitting with a recip saw and cold chiseling it out to cement in a new flange is about the only other proper fix. Bolt on flanges are extremely hit or miss.

I have used one of these, installed it a few years back.

I did this last year. Not as difficult as I was expecting.
I tried all the other "easy" fixes I could. Toilet was still leaking. Did the new flange and guess what, toilet was STILL FREAKING LEAKING!
Turns out the brand new toilet had a hairline crack that allowed a couple of drips a minute. I spent nearly 40 hours of my life trying to source the water. Food coloring in the toilet bowl without flushing helped diagnose.
