Ingredients
  

Sugar Cookies
  • 2.5 cups all-purpose flour leveled
  • 0.75 cup unsalted butter softened
  • 0.75 cup granulated sugar
  • 1 large egg room temperature
  • 1 tsp vanilla extract
Royal Icing
  • 3 cups powdered sugar sifted
  • 2 tbsp meringue powder
  • 5 tbsp water adjust as needed
  • 1 tsp lemon juice optional

Equipment

  • Mixing Bowl
  • Baking Sheet
  • Oven
  • Cooling Rack
  • Piping Bag
  • Piping Tips
  • Cookie Scoop
  • Tray
  • Freezer
  • Hand Mixer

Method
 

  1. Bake sugar cookies until lightly golden and cool completely before decorating.
  2. Combine powdered sugar, meringue powder, water, and lemon juice until smooth and glossy.
  3. Mix until the icing forms soft peaks and flows smoothly without becoming runny.
  4. Transfer icing to piping bags fitted with small tips for precise decorating.
  5. Pipe outlines first, allowing clean borders that guide the flood icing.
  6. Fill outlined sections with slightly thinner icing and smooth using a decorating pick.
  7. Allow cookies to dry completely before stacking, packaging, or adding extra decorative layers.

Notes

For softer cookie centers, reduce baking time slightly. For crispier texture, bake a little longer. Adjust icing thickness with tiny amounts of water for flooding or extra sugar for detailed piping. Freeze undecorated cookies in airtight containers for up to three months. Handle decorated cookies carefully until fully dry. Customize flavors with citrus, almond, vanilla, or maple extracts. Store finished cookies in airtight containers at room temperature.
