EDM 144- Draw something square

It took me a long time to settle on what to draw for this challenge. It seems that many things are not real squares - rectangle seems to be a more common shape. This is a piece of cake that we made for our recent extended family dinner. I'm a pretty good cook, but since I don't like sweet things very much, I have never baked much or practised much with deserts and things. I'm way better with main courses, and appetizers which are my real favorites. But you can't have the family over for dinner and not offer a desert. That would just be bad karma. But there were some boxes of cake mix high up in the cupboard waiting for just such a situation to occur. Shawn whipped up the cake and swirled the yellow batter and the fudge batter together ever so prettily. And we baked it in our swell new oven - first time for baking a cake. Later I decided that we were on a roll here, and I should make some chocolate icing from scratch. Really, how hard could it be? That was when I realised it had been so long since I had baked a cake that I couldn't remember how to make icing. Sadly, I had to check for a recipe. Oh yeah, there's butter in it, not just milk and icing sugar and lots of cocoa powder. It was pretty when it was done, especially when the sprinkles hid the slight lumpiness. And my gluttonous family ate the whole thing! Except for one piece that I saved for the next day, and it became the inspiration for square.
