The difference between buttercream icing and royal icing is in the ingredients, which produce vastly different results on desserts. So they have different purposes.
Buttercream tastes better and has a superior mouthfeel. Like its name suggests, this kind of frosting usually has butter, milk or cream, powdered sugar, and an extract flavoring, according to Bake Decorate Celebrate. The icing is smooth, creamy, and doesn’t dry out fast. Buttercream is best for frosting cakes, cookies, cupcakes, and other treats. You can adjust the ingredient ratios to get a consistency you like. It’s a forgiving type of icing.
Royal icing is less about the taste and texture. Super-sweet and hardening quickly, royal icing is into making a pretty appearance and having a function: a glue to hold decorations together. It’s what you use on gingerbread houses to make the candy stick and for your designs on sugar cookies. The ingredients in royal icing are usually powdered sugar, water, and meringue powder. People use royal icing to pipe intricate designs, make flowers, and adhere fondant to cakes.
So in the battle of royal icing vs buttercream for cookies, the winner isn’t clear. If you want a neat and clean, beautiful/cute design on your cookies, go with royal icing. Most people who are decorating cookies in the first place are going for the eye appeal, so it’s a popular choice. But if you value taste over looks, go with messy, delicious buttercream frosting.
