When you go to the trouble to make a homemade cake, making sure the cake is done is an important process. No one wants a cake that is either still raw in the middle, or dryer than day old bread. There is no one hard and fast rule for making sure that a cake is done in terms of cooking temperatures and times. Each cake will bake slightly different according to its ingredients, the oven you are using, and the size of the baking pan or dish.

Generally, one tests a cake by inserting a clean toothpick into the middle of the cake. If the toothpick comes out clean, the cake is done. If the toothpick comes out with crumbs, or clearly shows wet cake batter, the cake is not finished cooking. Don’t use a knife to test the cake as this can deflate a cake. If you don’t have a toothpick, you can substitute an uncooked spaghetti noodle.

Usually, the best way to ensure a cake is done is to rigidly follow the recipe ingredients. Substitutions like honey for sugar, or additions of wet ingredients like blueberries or bananas may result in a longer cooking time. In these cases, you can cook the cake until the time designated by the recipe and then test it, but you may need to add a little cooking time before the cake is done. Larger cakes usually require longer cooking at a slightly lower temperature. You may want to check the directions for baking doubled or tripled recipes.

There are often different cooking times for people who live in mountainous regions, and be certain also to check if you are using a convection oven, as these usually have much quicker cooking times. When one purchases a convection oven, it will also usually come with a book of recipes, or modifications that can help you determine when your cake is done. One can also purchase cookbooks designed for the convection oven, which are likely to yield better results than recipes designed for traditional gas or electric ovens.

Some cooks swear by the careful hand test to assess when a cake is done. They gently press on the top of the cake with the hand. If it feels firm, and does not give under the pressure, then the cake is done. It should spring back. The cake should only be pressed very lightly, or it can deflate the cake. Any significant amount of give suggests cooking the cake for longer. This method should be done carefully and quickly, since the cake will be quite hot.

To make sure your cake is done properly, you might also want to hang a thermometer in your oven and test the temperature. Slight variations in oven temperature can change cooking time. As well, older ovens may have hot spots that can affect larger cakes particularly. If you know of such hot spots, be sure to keep the cake away from them, or directly centered on them when possible, so the cake cooks through evenly.

Lastly, a good look at a cake, particularly those that are yellow or white can yield a lot of information about whether the cake is done. They tend to shrink from the sides as they become more cooked, though this is not usually the case with chocolate cakes, unless they contain a lot of butter. If the top seems to be getting golden or yellow, the cake is probably close to ready. If the cake still seems very pale, it may benefit from a few more minutes in the oven.
