A few years back Cake Pops took the world by storm. (To this day it's still one of the most popular recipes on our website!) If you're a fan, check out this creative way to put these tasty creations to use decorating another cake... on the inside!

The cake decorators at the blog Once Upon A Pedestal are known for their amazing designs. This one in particular uses white cake mix, a little food coloring (though you could use natural if you're opposed) and a two-step process to get the look above. Although they use a cake pop maker, you can make your own, but the rest of the process should be easy!

Cute!
The bottom picture with the three cake pans looks kind of like three bowls of giant Trix (the cereal).
So, those colored round cakes would be baked twice to achieve the final result? Enjoy that texture kids, at least it looks pretty.
I dont think standard cake balls (cooked cake mashed with icing) would hold up too well to this, god knows how that icing would bake, but the cake pop variety is a great idea!
I was wondering the same thing MIME25 - someone from The Kitchn should test it out using the "original" cake pop recipe and see what happens!
ALISONCMC: another baker has tried original cake pops with frosting. You can see her results here: http://www.SugarAndSpiceAndAllThingsIced.com/2011/10/polka-dot-cake/.
Seems to have worked except that the balls sank. Happy Caking!

I've made cupcakes with a cream cheese filling, which is very similar to the cake pop recipe, and it bakes up fine (it's supposed to be a "cheesecake filling").
