Decorating mitten cookies with royal icing is one of my favorite winter traditions. This easy and festive cookie decorating method is perfect for beginners, fun for kids, and great for holiday gifts or cookie swaps. Use bold gel colors, sanding sugar, and a few simple techniques to create cozy winter treats that look beautiful and taste even better.
Prepare the royal icing. Mix it to a 15-second consistency using meringue powder and divide it into small bowls. Add gel food coloring to match your holiday palette.
If you made your sugar or gingerbread cookies ahead of time, take them out of the freezer and let them come to room temperature before decorating.
Lay all your cookies in a single layer on the table or workspace. This keeps everything organized and helps the icing process go smoothly.
Outline and flood each mitten cookie with your base icing color. Use a scribe tool to even out the icing and pop any air bubbles for a smooth finish.
Once the base layer sets slightly, pipe the mitten cuffs with white icing. While still wet, add sanding sugar to give a fluffy, sparkly effect.Decorate each mitten with simple sweater-inspired details like dots, zigzags, hearts, or snowflakes using a contrasting icing color.For extra charm, top with sugar pearls, edible glitter, or festive sprinkles. Let the cookies dry completely on a cooling rack—this usually takes overnight.
