Dough Cutting

[wreath]

I'm making that dough animation on houdini reel/tutorial, having problem with intersecting

here ı'm attaching scene's flipbook, in the first one, cutter completely intersecting the dough and can't effect it enough, in second its working better but still intersecting a little and i don't want to use a brick to cut it need to use thin objects.

i tried (not worked) ;

+ increasing all solvers substeps

+ subdividing cutter

+ increasing particle fluid object's volume offset (it worked but looking unrealistic/weird)

so how can i solve this problem?

cheers
