I started with three round cakes (chocolate was his choice this year). I left one whole and gradually made each other one smaller. I used leftovers for the top and fourth level. I frosted each with chocolate frosting and frosted in between layers.
Now it was time to add the cascading lava. For this I used some extra strawberry frosting I had on hand. I added no-taste red food coloring. I loved this cake in that you couldn't mess it up, because volcanoes are already a mess!
A good exploding mountain needs rocks and boulders. I used CoCo Puffs for rocks and chocolate donuts for boulders.
Finally I needed something to explode out the top. I Googled homemade lollipop recipes and found one that wasn't too hard. Sugar, light corn syrup and water. I added red food coloring to half and yellow to the other. Then, instead of filling a candy mold, I drizzled it on top of greased wax paper. I only burned myself once (and in the process I learned that a meat thermometer is NOT the same as a candy thermometer)! It hardened overnight and was ready to insert into the top of the volcano (or Mt. Wanna-Hawka-Loogie as I fondly think of it) the next morning.
