Food Network’s royal icing, Eating Well’s chocolate cookie icing and Betty Crocker’s orange icing are three recipes for cookie icing. Each recipe incorporates confectioner’s sugar, also known as powdered sugar, to make a sweet cookie topping that hardens when dried.
To make Food Network’s royal icing, mix 1 pound of confectioner’s sugar, 3 large egg whites and 1/2 teaspoon of lemon juice in an electric mixer with a paddle attachment. Beat until the icing mixes completely and is thick and white. The icing takes five minutes to make and yields enough to ice 30 to 45 cookies, depending on the size of the cookies.
To prepare Eating Well’s chocolate cookie icing, microwave 1/4 cup of whole milk, until just boiling, and pour half of the hot milk through a fine sieve into a glass bowl containing 3 1/2 ounces of coarsely-chopped dark chocolate. Let the milk and chocolate stand, without stirring, for two minutes; then, vigorously stir the mix to begin melting the chocolate. Add the other half of the milk through the sieve, stirring the mixture until it’s smooth; then, sift in 3 tablespoons of confectioner’s sugar, and continue stirring until combined and smooth.
To make Betty Crocker’s orange icing, simply combine 1 cup of powdered sugar, 1/4 teaspoon of vanilla and enough orange juice to thin the icing to a good drizzling consistency, about 3 to 4 teaspoons.
