Explain please

What is happening in my render of this scene one donut with sprinkles icing isnt rendering

I can’t see the full outliner, but I would check if there’s render activated (no only viewport view) for that object.

i am a beginner please try to dumbed it down a lot

The outliner is the object list thingy in the top right.
Check if the little camera icon next to your icing is grayed out.

thnx helped
