How to make hair particles stop hovering above an object?

Hey guys,

This is my first post here. I am doing the beginners tutorial by Blender Guru, and have been trying for days to make everything work. I have tried his particle tutorial twice, but just can’t seem to make the particles stick to the icing as they do in his video. I will attach the file here: (235 KB) if anyone wants to take a look.

Or if this is a common “idiot” mistake, I would love some help.
