I want to bake 3 cakes continuously If so do you need preheat the oven every time?

You only need to preheat the oven once for baking three cakes continuously. Here's why:

* Consistent Temperature: Preheating ensures the oven reaches the desired temperature for baking. Once it's hot, it will maintain that temperature unless you open the door frequently.

* Time Efficiency: Preheating the oven takes time. You'll save time by preheating just once and baking all three cakes consecutively.

Important Note: Make sure to allow enough time between cakes for the oven to recover to the correct temperature after the first cake is removed. This usually means about 5-10 minutes of rest time.
