Bubbles can form in cake batter either from over-mixing or simply because of the presence of chemical leavener — either baking powder or baking soda — used to help the cake rise.

Why do cakes get air bubbles?

The bubbles are pockets of air that can't release from the batter before the baking process ends. The air is often introduced into the batter by overbeating. The bubbles can also come from carbon dioxide trapped in the cake from a failed leavening reaction.

Should polymer clay bendy after baking?

Polymer clay beads should be bendable if they are baked correctly. Under-baked polymer clay won't be bendable. It will be brittle and easy to break. So if you can bend your beads without them snapping, like the one in the photo, then you're baking polymer clay the right way.
