Prep
10 min
Yield
Icing for ~24 4" sugar cookies

Directions

  1. In the bowl of a stand mixer, combine water and meringue powder. Using the whisk attachment, mix on medium-high speed until white, frothy, and doubled in size (1-2 minutes).

  2. Using the paddle attachment, gradually add sugar and mix on medium speed for 4-6 minutes. Add corn syrup and vanilla/almond extract.

  3. Check the icing consistency - different decorating steps call for different textures:
    - Extra thick: does not flow off the whisk at all; very stiff.
    - Thick: flows off the whisk slowly and smooths out in 18-20 seconds.
    - Medium: flows off at a medium speed and smooths out in about 15-17 seconds.
    - Thin: flows off quickly and smooths out in about 10-12 seconds.

  4. To reach the desired consistency, add warm water one tablespoon at a time, mixing and checking the consistency before adding more.

Tips

  • Keep unused icing covered with a damp paper towel or plastic wrap so it doesn't dry out.
  • Icing too thin? Add powdered sugar a little at a time until it firms up.
  • Add 1 tsp vanilla or almond extract for extra flavor.
  • Let decorated cookies dry several hours or overnight, depending on thickness.
