So I needed to level a bunch of cakes and I seemed to have found a solution (I am so proud of myself!). Take 2 boxes (I used latke mix) and put the cake in between them. Then I used the blade off of my electric knife to level them. The key to blade choice is one that is totally flat on one side. You will notice in the pictures that the white part is only on one side. If you don’t have a blade that doesn’t lie flat or is handle-free you can get a hack saw blade from the home store.
