Icing On The Cake Recipe At Home. On a stand mixer fitted with whisk attachment beat egg whites in a clean large bowl with the mixer at high speed until foamy around 2 minutes. Spray and flour a 13x9 cake pan.
Royal icing is easy-to-make looks great and lasts long but is made with raw egg whites. For exceptionally smooth frosting dip the spatula into hot water then dry it. In a large stand mixer combine all of the ingredients.
For thicker icing add a little more.
The warm spatula will really help smooth the frosting out by melting any butter or shortening in your recipe. Add the vanilla extract and combine thoroughly. Preheat oven to 350. Cool on wire rack for 15-20 minutes and then unmold.
