Hi there, Jenniffer! Often times when a cake sinks while in the oven, it is because the batter was over-mixed and too much air was knocked out. Without knowing much about your recipe, it can be hard to tell what might be going on though. Some suggestions for troubleshooting are to whip up the whites and use a sponge cake-like method, reducing the sugar a tad (about 15 to 20 percent), and shortening up your mixing times as well as using a spatula to scrape the bowl often. We hope this helps and best of luck with your recipe. Kindly, Morgan@KAF
