Servings 7 dozen mini cookies


  • plastic pipette
  • paint palette dedicated for food or small dishes
  • food grade paintbrushes


  • 1 batch small (1 inch) star shaped sugar cookies or shortbread cookies (iced with royal icing or simple egg free icing, see note)
  • gel food coloring in rainbow colors
  • grain alcohol (such as Everclear)
  • gold luster dust


For Rainbow Painted Cookies:

  • Place drop of food coloring gel into the well of a paint palette or small dish. Add alcohol drop wise and mix well with paintbrush. Add additional drops of food coloring to achieve desired color.
  • Brush color across surface of the cookie in long brush strokes. If color is not as deep as desired, allow to dry and apply a second coat.
  • Repeat with all colors desired, rinsing and drying paintbrush well between each color or using a new paintbrush for each color.

Dry Application of Gold Dust:

  • For just a hint of shimmer, brush gold dust onto icing. This can be done on the plain iced cookies and the rainbow painted cookies after the paint has fully dried.

Wet Application of Gold Dust:

  • Add some gold luster dust to the well of a paint palette or small dish. Transfer a few drops of alcohol and mix well with a paintbrush. Add more dust or alcohol depending on how thick the liquid is. You want an intense gold color but it should still be liquid, not a crumbly mixture.
  • Submerge paintbrush in gold suspension then tap it to the inside of the well or dish to allow excess liquid to run off. Sweep the gold across the surface of a cookie in long strokes, trying not to overlap brushstrokes.
  • For a deeper gold color, allow to dry completely and add a second coat of liquid gold.

For Most Intense Gold Color:

  • Before icing the cookies that will be painted gold, add gold gel food coloring to the wet icing.
  • Ice cookies as normal and allow to dry completely.
  • Either brush cookies with dry gold dust, or for optimal gold color, follow instructions for making a liquid gold suspension to paint across surface of cookie.

To Store Painted Cookies:

  • Allow edible paint to dry completely before storing. Store in a single layer in an airtight container at room temperature.
  • To freeze, place in a freezer storage bag or container in a single layer. Thaw at room temperature before consuming.


For best results with gold color, tint the icing for a portion of the cookies with gold gel food coloring prior to applying icing to the those cookies.
