My youngest just turned 5 and is recent obsession is fishing. He would also like to eat chocolate every day for breakfast. For his birthday, I made a chocolate cake, blackout style. The difference being instead of cake crumbs on the outside, I used crushed Oreos. On the top, I frosted a lake with candy bubbles. The dock is made from Popsicle sticks and hot glue, with a Playmobil guy fishing off the dock. His pole is just a skewer with thread and a wire hook. We later added Swedish fish to the lake, which completed the look. It was fun to make and the kids helped. Other than melted chocolate being splattered hither and yon by an enthusiastic whisk-er, it was quite enjoyable.
