I used canned frosting for this project...and I also ate the slice that leveled off the bottom. Of course I frosted the slice first. Who can cook chocolate without eating it? Wow...it was definitely an aw moment when I bite into the slice. I applied the frosting with a spoon dabbing it on the entire top. Then I took the spoon and evened it out. After that I took the same spoon started at the top and followed the swirls. Topped it with large candy dots and sprinkles.
