Round Collapsing Toolbar android

I'm trying to make my collpasing toolbar have round corners when collapsed. I have an image inside of it that has rounded corners, so when the toolbar is expanded it looks like it has rounded corners, but when I collpase it the collpsed toolbar is squared. Is there a way to make it round ?

My xml:
