You can put decorations on sugar cookies using a two-layer icing method.
Two-Layer Icing Decoration Method
The most common and effective method for decorating sugar cookies involves creating a smooth base layer of icing (often called "flooding") and then adding decorative details on top once the base layer has dried.
Step 1: Flood Icing (Base Layer)
-
Prepare Flood Icing: This icing should have a consistency that allows it to spread easily but not run off the edges of the cookie. Typically, royal icing thinned with water is used.
-
Outline the Cookie: Use a piping bag fitted with a small round tip to outline the edge of the cookie with the flood icing. This creates a dam to contain the icing.
-
Flood the Cookie: Fill in the outlined area with the flood icing. You can use a scribe tool, toothpick, or shake the cookie gently to help the icing spread evenly and eliminate air bubbles.
-
Let it Set: Allow the flood icing to dry completely for at least 1-2 hours. This creates a stable base for your decorative details. Proper drying is essential to prevent colors from bleeding and designs from sinking.
Step 2: Decorative Icing Details
-
Prepare Decorative Icing: This icing can be the same royal icing used for flooding, but possibly with a slightly thicker consistency for better control when piping details. Food coloring can be added to create different colors.
-
Piping Designs: Using piping bags fitted with various tips (round, star, petal, etc.), pipe decorative details onto the dried flood icing. This could include:
- Swirls
- Handwriting
- Dots
- Flowers
- Geometric patterns
-
Other Decorations: You can also add sprinkles, edible glitter, candies, or other edible decorations while the decorative icing is still wet so that they adhere properly.
-
Final Drying: Allow the decorated cookies to dry completely before packaging or serving. This can take several hours or overnight.
By using a two-layer icing method, you can create beautiful and professional-looking decorated sugar cookies.
