Cauldron Cake

Neon food color. Which you can find at most grocery stores or on Amazon. How simple is that? And SO FUN! You can use as much or as little food color as you would like but I ended up adding about 1 teaspoon. All I could think as I was making it was double double toil and trouble. 
I added roughly 1 cup of pudding to the top as I wanted to make sure it didnt all spill down when I cut into the cake. However you can easily add more! If you want more green slime pudding I recommend carving out a bit of the top so there is a little cake bowl that can hold it all in. My kids loved getting to eat the extra neon green pudding I had left over. You can also save the extra green slime and serve more with each individual piece.
How and When to Serve a Cauldron Cake
I highly recommend serving it soon after assembling. I did notice that the black food color bleeds slightly into the pudding the longer it sits. My friend that it was a really cool effect but if you want to avoid it try to serve immediately.
The first time I made this cake I chilled for about 12 hours before serving. The cake holds up beautifully but there is that slight bleeding into the pudding. The second time we cut into it immediately after assembly and I could not have been more thrilled with how beautifully it all holds together. The trick to that perfection? Make sure your cake layers are VERY chilled when assembling the cake!
Tips for Black Buttercream
My favorite secret tip for black buttercream is starting with a chocolate frosting base. Everyone loves chocolate frosting!
