Royal Icing for Cakes

A classic white icing made with egg whites and powdered sugar, perfect for decorating cakes with a smooth, elegant finish. This traditional royal icing dries to a firm, glossy surface.

  • 4 whole Egg whites, large (Room temperature works best)

Instructions

  1. 1In a large bowl, beat the egg whites with an electric mixer on medium-high speed until very light and foamy, about 2-3 minutes.
  2. 2With the mixer running on low speed, gradually add the sifted powdered sugar, about 1/4 cup at a time, beating well after each addition. This should take about 5 minutes total.
  3. 3Add the lemon juice and continue beating on medium-high speed until the icing is very light, white, and holds stiff peaks, about 3-4 minutes.
  4. 4Place your cooled cake on a wire rack set over a baking sheet to catch drips. If desired, you can warm the cake slightly by placing it near (not directly in front of) a warm oven for 1-2 minutes to help the icing spread smoothly.
  5. 5Pour the icing over the top of the cake, allowing it to flow naturally down the sides. Using the back of a large spoon or an offset spatula, smooth the icing over the top and sides of the cake in long, even strokes.
  6. 6Allow the icing to dry completely at room temperature, which will take 2-4 hours depending on humidity. The icing will harden to a smooth, firm finish.
