Step 3: Ball it Up
This is really baker's choice - how big, what shape and how to make them.
I don't have one of those little melon-baller gadgets, but I might get one for the next round - my hands seems incapable of rolling a sphere - they all come out like footballs. It took some work to make the beautiful spheres you see here.
Nonetheless! Roll your cake mash into ball-like pieces. Mine were about 1 1/4" in diameter.
Stick em in the fridge.
