What reasons a sheet cake to sink within the center after it has baked and starts cooling? How can I prevent this from happening? —J.B., Lombard, IllinoisA sheet cake may upward thrust after which sink after baking if the oven isn't always warm sufficient. If your cake sinks, check the accuracy of your oven temperature with an oven thermometer. If a cake hasn’t been in the oven long enough, it, too, will sink. To check for doneness at the stop of baking time, insert a toothpick near the middle of the cake. If the toothpick comes out easy, the cake is achieved. If the perimeters of the cake begin pulling faraway from the pan, it's miles every other indication that your cake is performed. Other cake sinkers consist of undermixing the batter, shifting the cake at some stage in baking, the usage of a pan that’s too small for the quantity of batter, and adding too much sugar or leavening or too little flour to the batter.
