This step-by-step guide with photos will teach how to get crisp sharp edges on any square cake covered in buttercream

Sally Cake - BKeith Ryder 1. First, a square “cake” (sorry — didn’t have a real cake around to mess with). Slapped some icing on a square pan, and when I went to clean some icing away, I came up with a perfect square corner without even trying. angry.gifSo I took an intentional swipe at the corner to mess it up a bit so you could see what’s what.

I use this method all the time, but instead of two spatulas, I use a metal scraper on the corner and wipe it with the spatula. Then I pull the metal scraper back slowly so as not to damage the corner (as though I was smoothing the side of the cake). Works great.

This worked like a charm! My go-to method all the time since I saw this. It works great with BC and ganache!
