Common Mistakes to Avoid

When making sugar cookie icing that hardens, it’s easy to make some common mistakes. Here are a few tips to help you succeed!

Bold Temperature Matters: If your kitchen is too hot, the icing might not set properly. Consider cooling your workspace or letting the icing sit at room temperature after decorating.
Bold Color Mixing: Adding too much gel food coloring can change the consistency of your icing. Start with small amounts and gradually increase until you achieve your desired color.
