Never again will I make a cake that requires me to crumble cake and mix it with frosting then mold it into a shape. Never. Again.
The Easter Egg Cake from Serious Eats came out much better than mine did. I would have been better off making the cake that site links to, which has better layers.
The problem started when I didn’t cut the layers correctly, leaving a big gap between the back and front halves of the cake. I ended up cutting the circumference of the back half and mushing up that part of the cake to make some cake spackle to bridge the difference between the high and the low.

Here’s the finished product. I ended up running short on frosting (blame the cake/frosting spackle?) and by the time I got all the crumbs moderately covered, I just sprinkled the sanding sugar on top rather than make a pretty design. I was done.

It didn’t cut nicely in layers, which makes sense as much of it wasn’t a layer but was cake spackle, but it did taste good. Especially with Rick’s homemade ice cream.
