Cakes Have Excessive Shrinkage (excessive pulling away from the sides of the pan): The oven temperature may be too high. The baking time may be too long. The pans may be too close to each other or too close to the oven walls.
Cooling cake layers on a cake rack, allows air to circulate and prevents the layers from being “wet” on the bottom. Turning a warm or hot cake out of a baking pan too quickly, will crack and fall apart. Cake layers that cool in the pan too long will stick unless lined with parchment paper.
Yes. Adding too much baking powder or baking soda can make a cake sink. When too much amount of leavening agents are added, there can be too many air bubbles develop in the batter and the cake may rise too much without enough support, then it sinks.
The edges pull away
Once your cake nears the end of the bake time, peer through the oven window and check the edges of the cake. When your cake is done, the sides will have pulled away from the pan slightly. The edges of the cake are the first part to set and become fully baked.
Make sure you follow the recipe's instructions carefully. Cakes typically bake between 325 to 450 degrees F (see chart with Tip #9). Most convection ovens require lowering the temperature by 25 to 50 degrees F, as well as turning off the fan.
The cake pan is heating up much faster than the rest of the cake. This causes the edges to set before the cake has risen fully, and as the rest of the cake cooks the centre rises and creates a dome. To stop your cake from doming, line the outsides of your cake tin with a double layer of foil.
When the cake first comes out of the oven, it's cooked through but the hot "crumb" — the mass of the cake — is delicate. If you try to get it out of the pan too soon it can stick to the pan, break, or both. For most cakes, allow around 20 to 30 minutes at room temperature for cooling (per MasterClass).
Other cake recipes specify setting the pans on a cooling rack and cooling the cake in the pans for a short time (usually in the 10-minute range) before removing the cake. Set a kitchen timer for this step. Cooling the cake too long in the pan might make it difficult to remove.
The answer to this will also depend on the type of cake you are making! Usually, the recipe will give instructions on how to cool the cake. Most cakes will need to be removed from their tin after 15-20 minutes. But something like a fruit cake or baked pudding will need to be cooled completely in its tin.
The most common reason why cakes sink in the middle is that they're underbaked. If a cake isn't fully baked through, the center doesn't have a chance to set and it will sink. This creates a doughy, dense texture in the center of your cake layer.
But even in these stickier situations, there's a good rule of thumb that'll save you the mess every single time: Only fill your cake pans three-quarters of the way. Give your cake some breathing room, even if it means you've got leftover batter.
For best results, you should fill your cake pan 2/3 full with batter. This gives your cake plenty of space to rise. If your cake pan is overfilled, the batter can overflow, causing your cake to bake unevenly (and creating a terrible mess in the oven!).
If the oven temperature is set too low, the outer layers of the cake will cook faster than the center, leaving the middle raw. What is this? Additionally, if the cake is placed too high in the oven, the middle will not receive enough heat to cook. This can also lead to an underdone middle.
In order to bake cake evenly, you have to insulate its edges. Preventing the temperature of batter at the edge from increasing quickly allows the cake to rise longer before it sets. A cake whose edges rise at nearly the same rate as its center will remain flat across the top — no dome, perfect for stacking and icing.
Reason #1: Air has got trapped between the Cake Layers
This is one of the most common reasons why cakes bulge. Sadly, most bakers fail to rectify this error. This depends on how you add the filling between the layers.
An oven that is too hot can also cause uneven baking. Test the oven temperature when preheating the oven by using an oven thermometer and adjust as necessary. Opening the oven door during baking causes uneven heat distribution and abrupt temperature fluctuations which can also cause the cake to rise unevenly.
Too much baking powder will cause a cake to rise too quickly and too much, making it crack or spill over the sides of the tin.

Cake Baking and Temperature Time
Typically, a cake is baked at a temperature of 180-190 degrees Celsius for 25-30 minutes. However, the temperature and time may vary depending on the recipe and the size of the cake. It's crucial to follow the recipe instructions carefully to achieve the best results.
If you are using an electric oven, cook at 180 degrees for 30-35 minutes.
For a clean release, grease, flour—and parchment—are key. It may sound like overkill, but the most effective way to ensure that a cake releases cleanly from a baking pan is to grease the pan, line it with parchment paper, and then grease and flour the parchment and pan sides.
