#### **Step 1: Make the Royal Icing**
In a mixing bowl, beat powdered sugar and meringue powder (or egg whites) on low speed.
Add water one tablespoon at a time until the icing is thick but smooth.
Beat on medium-high speed for **3-5 minutes** until the icing forms stiff peaks.
Add vanilla extract and mix for another minute.
#### **Step 2: Adjust for Piping or Flood Icing**
- **For Piping & Borders**: Use as is for a stiff consistency. Transfer to a piping bag and use a small tip for outlining cookies or creating details.
- **For Flood Icing**: Thin the royal icing by adding 1 teaspoon of water at a time until it reaches a smooth, flowing consistency. When drizzled with a spoon, it should settle back into itself within **5-10 seconds**.
#### **Step 3: Decorate Your Cookies**
Pipe an outline around the cookie with royal icing.
Fill inside the outline with flood icing, using a toothpick to spread evenly.
Let the icing dry for **6-8 hours** at room temperature until hardened.
