You can determine when a cake is baked:
- When the cake’s side pulls away from the pan
- And, when a knife inserted in the middle comes out clean; if traces of batter are seen, then continue baking and testing again (after 5 minutes) making sure that knife comes out clean with no traces of batter
When cake has finished baking, remove it from the oven and allow it to cool in its pan, on a cooling rack for about ten minutes. This allows cake to keep its shape as it cools off.
To remove cake from pan, run a butter knife around the pan, between the cake and the side. Invert cake onto a cooling rack; lift off pan (and any wax paper), and return cake to an upright position; allow to cool completely on cooling rack.
When a hot surface comes into contact with a cold surface, or cold air mass, condensation might develop (water might be absorbed by the cake, causing it to have a soggy bottom, which might make it stick to its pan
Racks allow cakes to cool off at a faster and equal rate, and also prevent them from becoming soggy.
