Ingredients Equipment Method

Ingredients
  

  • 2 cups powdered sugar finely sifted
  • 1/2 cup unsalted butter softened
  • 2 tablespoons heavy cream
  • 1 teaspoon vanilla extract
  • a pinch salt sea salt flakes preferred
  • optional food coloring gel preferred

Equipment

  • Heatproof mixing bowl
  • Spatula
  • Fine sieve
  • Offset spatula

Method
 

  1. Place your sifted powdered sugar into a heatproof mixing bowl. Add a pinch of salt and whisk together to evenly distribute.
  2. Add the softened butter to the bowl and begin mixing with a spatula until the mixture is smooth and creamy, about 2 minutes. You should see a pale, fluffy texture forming.
  3. Pour in the heavy cream and vanilla extract, then continue mixing until the frosting becomes glossy and smooth, about 1-2 minutes. This helps develop that beautiful sheen.
  4. If you'd like to add color, mix in a tiny drop of gel food coloring now. Stir thoroughly until the color is evenly dispersed and the frosting is vibrant.
  5. Check the consistency; it should be silky and spreadable with a slight shine. If it’s too thick, add a tiny splash more cream and mix again. If too thin, sprinkle in a bit more sifted powdered sugar and stir to combine.
  6. Use an offset spatula to spread a thin, even layer of frosting over cooled sugar cookies, smoothing the surface gently for a mirror-like finish.
  7. Allow the frosted cookies to rest at room temperature for about 10 minutes. This helps the frosting set and develop that glossy, reflective surface.
  8. Once the frosting is shiny and firm to the touch, serve your cookies immediately or store in an airtight container for up to 2 days. Enjoy the stunning, bakery-quality finish!
