Put all the cake ingredients in a large bowl and stir to a creamy mass. Divide the batter between different sized pairs of bowls and bake at 340°F for 30 minutes.
Let the little cakes cool down a bit and then cut off the excess cake tops with a knife, just above the rim of the bowl.
Coat each half of the cake pairs with chocolate buttercream frosting, gently press the other cake half on top, and remove the upper bowl.
Carefully insert a stick into the cake pop, turn the whole thing over, and remove the bottom bowl.
Frost the entire cake pop with chocolate buttercream.
For the glaze, add the sugar, water, and condensed milk to a saucepan and bring it to a boil while stirring with a whisk. Reduce the heat so that it is no longer bubbling, and stir in the gelatin sheets and white chocolate. Carefully purée the mixture. Then place the majority of the glaze in a bowl and spread the rest on a plate.
Add a few drops of green food coloring to the glaze on one half of the plate and a few drops of brown food coloring on the other side. Stir each color with a spoon, but make sure not to let the two colors mix or run together. Use blue food coloring on the glaze in the bowl.
Completely submerge the cake pop in the blue glaze. Then decorate it with the colors on the plate by dipping it in different places in the glaze. You can also use your fingers to create more specific decorations.
