Ingredients
  

Frosting Mixture
  • 4 cups Powdered Sugar sifted
  • 5 tbsp Milk add as needed
  • 2 tbsp Light Corn Syrup improves flexibility
  • 1 tsp Vanilla Extract for flavor
  • 1 pinch Fine Salt optional
Flavor Options
  • 1/4 tsp Almond Extract optional
  • as needed Food Coloring optional

Equipment

  • Mixing Bowl
  • Hand Mixer
  • Measuring Cups
  • Measuring Spoons
  • Rubber Spatula
  • Cooling Rack
  • Freezer
  • Tray
  • Cookie Scoop
  • Baking Sheet
  • Oven

Method
 

  1. Combine powdered sugar and salt in a mixing bowl until evenly blended.
  2. Add milk, corn syrup, and vanilla. Mix until glossy, smooth, and pourable.
  3. Adjust consistency gradually. The frosting should flow slowly from a spoon without becoming watery.
  4. Spread or pipe onto fully cooled baked goods. Cover surfaces evenly for the best finish.
  5. Gently tap the tray to release air bubbles and encourage a level coating.
  6. Allow frosting to dry at room temperature until firm. Avoid moving treats during the setting stage.

Notes

For a softer bite, add a small amount of extra milk. For a firmer, crisper finish, increase powdered sugar slightly. Freeze decorated treats only after the frosting fully hardens. When assembling stacked desserts, handle gently and chill briefly if needed. Customize with citrus, almond, maple, or peppermint flavors. Store in an airtight container at room temperature for several days.
