Ingredients
  

  • 3 cups powdered sugar
  • 3 tbsp orange juice
  • 1 tsp lemon juice
  • 1 tbsp orange rind (grated, zest)
  • 3 tbsp butter (softened)
  • 1 egg yolk
  • 1 pinch salt

Instructions
 

Step 1: Prepare Ingredients

  • Zest the orange and separate the egg yolk.

Step 2: Cream Butter and Egg Yolk

  • In a large bowl, cream together the softened butter and egg yolk until smooth and pale.

Step 3: Add Citrus Juices and Zest

  • Add the orange juice, lemon juice, and orange zest to the mixture. Stir until well combined.

Step 4: Incorporate Sugar and Salt

  • Gradually add the powdered sugar and a pinch of salt, beating until the frosting is smooth and spreadable.

Step 5: Adjust Consistency (if needed)

  • If the frosting is too thick, add a few drops of orange juice. If too thin, add a bit more powdered sugar.

Tips

  • Substitute lemon juice with lime juice for a tropical twist
  • Use blood orange juice for a colorful and tangy variation
  • Add ½ tsp vanilla extract for a richer, more balanced flavor
  • Replace butter with vegan margarine and omit the egg yolk for a dairy-free version
  • Whip in a bit of cream cheese for a tangy, thicker frosting ideal for layer cakes
