Bright and citrusy, my easy lemon buttercream frosting is quick to make and full of tart lemon flavour. This frosting is summer in a bite and easily made in under 10 minutes!

Ingredients
  

  • 1/2 cup (113g) unsalted butter room temperature
  • Zest from 1 lemon
  • 1/4 tsp salt
  • 3 cups (420g) icing sugar
  • 2 1/2 tbsp fresh lemon juice
  • 2 tbsp milk

Instructions
 

  • In the bowl of a stand mixer or large mixing bowl, add the butter and lemon zest. Beat on medium high speed for 3 minutes until fluffy. Add in the salt and mix at low speed until incorporated.
  • Sift in half the amount of icing sugar and mix at low speed until starting to incorporate. Then beat at high speed for additional 30 seconds. Add in the rest of the sugar and lemon juice. Again mix at low speed until incorporated. Add in the milk.
  • Beat on high speed for additional 1-2 minutes or until light and fluffy. If your frosting is a bit too thick to pipe, add in milk, 1 tbsp at a time until you reach the desired consistency.
  • To get the air bubbles out, mix the frosting by hand with a spatula for 1-2 minutes. This helps give you a smooth frosting when piping. Then, add the frosting to a piping bag and use as desired. Store any leftovers in the fridge for up to 5 days or in the freezer for up to 3 months and enjoy!
