Making beautiful decorative cookies is easy using Royal Icing. I use meringue powder to make my royal icing. I find it so much easier to use and to attain the desired consistency instead of using an egg white version. Royal icing made with meringue powder will keep up to a week in an airtight container at room temperature.

Step by Step instructions for decorating cookies.

Preparing icing

Sift together confectioner’s sugar and meringue powder. Then using electric mixer, beat the confectioner’s sugar, meringue powder and water for 7 minutes. At this stage the icing will be very thick.

Outlining cookies with royal icing

Place a cup of the icing into a separate bowl to prepare the icing for doing the outline. Adjust the amount you need depending on how many cookies you are decorating. Cover remaining icing immediately with plastic wrap to prevent drying out.

Add a small amount of water (1/4 teaspoon at a time) to the icing. Stir well after each addition of water. This step is to thin the icing to a slightly stiff consistency, yet will hold together when a spoon is lifted from the icing. Pour into a piping bag or squeeze bottle. Use a round #2 tip to outline the cookies.

Flooding cookies with royal icing

Using about 2 cups of icing add water a very small amount at a time (droplets at a time) to thin to the icing to a consistency that would be similar to table syrup. When you run a knife through the icing the line disappears in about 10 seconds. Pour into a piping bag or squeeze bottle and using a round #4 tip cover cookies completely with icing.

I use a toothpick to spread the icing to the edges.

Use the pointed side of a toothpick to prick any air bubbles. Do this IMMEDIATELY, as it can’t be done if the icing starts to harden.

Let dry completely, at least 8 hours or overnight. Do not cover cookies.

Decorate as desired by adding a tad of gel food colouring to icing that is the same consistency as outlining icing.
