This was Nathaniel's 7th birthday cake! It was an erupting volcano... how fun is that!
It was one of the easiest cakes I've done as far as the decorating!
2 chocolate cake mixes
1 jar marshmallow fluff (or creame)
1 bag chocolate chips
karo syrup (light)
red food coloring
cup/glass/ flower vase
Bake cake according to directions. 1 cake mix in a bundt pan. The other (I used a medium metal mixing bowl...it was the perfect size... it took quite a bit longer to bake, and the very middle did not ever get done fully, but since you cut that out... no big deal... I pulled it out after 50 minutes)
Let cakes cool completely. When cooled cut a hole in the "mixing bowl"cake. Layer.. the bundt cake down first, then the "mixing bowl" cake on top. Fit your cup/glass/flower vase down into the hole, so the top does not stick out. To make glaze, melt 1 cup chocolate chips, 4 T of butter/margarine and 2 T of Karo syrup in microwave safe bowl. I used a bar-b-q brush to "paint" on the glaze then drizzled the rest over the top to give it a Mountain like appearance. Then heat marshmallow fluff for a few seconds in microwave until easy to work with. Snow cap your cake to your liking! Then take your red food coloring and a butter knife and add some lava for effect! I also put some chocolate sprinkles and extra chocolate chips on bottom for added rocks and dirt! Now... when it's time for the party... chop off a couple of small ice cube sized chunks of your dry ice and put them in a cup... (REMEMBER: DO NOT touch the dry ice with your bare hands... OUCH!!! Use gloves when handling dry ice!!!!!!!) Have warm water in another cup... when its time to explode... dump the "dry ice cubes" into the cup in the middle of your cake, then add the warm water and watch the fun~! You can also have a "Lava Explosion" by adding a bit of warm water to some marshmallow fluff to pour over the dry ice! I didn't want to go there for my first time, but it is a cool effect! We had an ExPlOsIvE PaRtY!!!!!!
