I’m am currently on a retro sheet cake mood and I remembered that Costco cake that was at every get together along with other cake selections. But in the time of smaller gatherings do we really need a full sheet cake. This is my take on that Costco classic.

My thoughts
Okay this cake was soooooooo delicious. I was 100% worried that the filling would leak even with the frosting barrier. I have never added a filling to a cake and I just didn’t know the outcome. Well I was unnecessarily worried as the filling stayed put and you know what it tasted delicious. The cake was moist with a nice crumb and the filling was creamy and rich with vanilla. The decoration was done in that retro style and lettering. My decorating skills are still lack luster but I see small improvements and for my first time piping cursive and it was half decent. One day I will have the most perfectly decorated cake however; for now taste and love will have to bring my cakes home.
