- 1). Wash your hands with anti-bacterial soap and water to prevent the spread of germs to the fondant. Dry your hands thoroughly before continuing.
- 2). Cover the index and middle finger of your dominant hand with shortening, such as Crisco. The shortening will help smooth out the fondant on the cake more easily. Use your dominant, steadier hand when performing any delicate fixes on fondant.
- 3). Rub the cracked area with your shortening-covered fingers using a circular motion. This will smooth out the fondant and make the crack less noticeable. Avoid using a back-and-forth motion to work the shortening in because this will leave behind streaks on the finished product.
- 4). Work a small amount of fondant into the crack with your finger, if the shortening does not fix the crack. Once again, use a circular motion to work the fondant into the crack, which will cover it completely.
