Here you go to hide mutual friends on facebook.
1) Suppose there is one profile "A" on facebook, who is your friend
Profile "A" is having friendlist hidden as we explained in earlier article of How to Hide Friend List on Facebook.
2) Let's assume, "A" is having a friend named "B"
When you visit profile of "B", "A" should come in mutual friend list between you and "B" but if you notice it, you cannot see "A" over there, because "A" has kept his friend list hidden and hence Facebook will not show "A" in mutual friends.
So, this is the only way your Mutual friends can be hidden, which means if a person in your friendlist is having their friendlist is secure, then only that person can not be seen in mutual friend list between you and your friends.
