Do you let a pineapple upside down cake cool before flipping out of pan?

Yes, absolutely! You should let a pineapple upside-down cake cool completely before flipping it out of the pan. Here's why:

* Prevents Breakage: The cake is delicate, especially right after baking. If you try to flip it while still hot, it could break apart or fall apart.

* Easier Release: As the cake cools, it will shrink slightly, making it easier to release from the pan. The caramel topping will also harden, making it less likely to stick.

* Even Cooling: Allowing the cake to cool completely helps ensure that the entire cake cools evenly.

Here's a general timeframe:

* Let the cake cool in the pan for at least 30 minutes. This allows the cake to set and the caramel to harden.

* Then, carefully invert the cake onto a serving plate or cooling rack. This will help it cool further and prevent condensation from forming on the top.

Tip: If you're worried about the cake sticking, you can run a knife around the edges of the pan before flipping.
