Checking the doneness of a cake without relying on cracks on the top can be done using various visual and tactile methods. Here are some techniques to determine if a cake is fully cooked inside:
Insert a toothpick or skewer: About 5-10 minutes before the recommended baking time is up, insert a toothpick or skewer into the center of the cake. If it comes out clean or with only a few moist crumbs clinging to it, the cake is likely done. If there is wet batter on the toothpick, the cake needs more time to bake.
Press the center: Gently press the center of the cake with your fingertip. If it springs back and feels firm to the touch, it is probably done. If your finger leaves an indentation, it may need more time to bake.
Check the color: The cake should have a uniform, golden-brown color on the top and around the edges. If the center looks paler than the rest, it might still be undercooked.
Listen for a hollow sound: When the cake is close to being fully cooked, you might hear a slightly hollow sound when tapping the top with your finger. This can be an indicator that the cake is done.
Use an instant-read thermometer: If you have an instant-read thermometer, you can insert it into the center of the cake. The internal temperature should reach around 210°F (99°C) for most cakes when fully baked.
Shrinkage from sides: The cake will usually start to pull away slightly from the sides of the pan when it's done. However, this alone is not a foolproof method, as some cakes might not exhibit this behavior.
It's essential to avoid opening the oven door too frequently during baking, as this can cause fluctuations in temperature and affect the cake's rise and even baking. Aim to check for doneness toward the end of the suggested baking time to minimize any disruptions.
Remember that the baking time may vary depending on the type of cake, the size of the pan, and the accuracy of your oven's temperature. Trusting your senses and using the methods above will help you achieve a perfectly baked cake without relying on cracks on the top.
