This is getting to be a THING, methinks...
I made this for the cake walk at my work and the woman who picked it was very pleased! She had a gathering the next night and said all her friends enjoyed it and asked for the recipe! It was awesome!
It was just my usual chocolate cake in two layers and vanilla buttercream (recipe here). The lady who took it really liked the frosting. lol. I thought, who doesn't??
The black is the premade Wilton tube frosting; I didn't want to mess with trying to color my own because black is never as good as Wilton's makes it. And it tasted fine!
It didn't come out perfect; if I were to do it again, I'd use a thinner tip for the web and I'd make a GIANT spider (possibly with balloons...)
