  • 8 ounces cream cheese (1 bar)
  • ½ cup butter 113g softened
  • 1 tbsp lemon zest
  • 1/2 tsp lemon juice
  • 4 cups confectioners sugar 454g
  • ½ tsp milk


  • In the bowl of a stand mixer fitted with the paddle attachment cream the block of cream cheese and ½ cup butter on medium speed until evenly combined.
  • Add in the 4 cups of confectioners sugar and mix on low speed.
  • Mix until creamy, about 2 minutes.
  • Add in lemon zest, ½ tsp lemon juice, and ½ tsp milk, and mix again until combined and super fluffy.


  • This recipe makes enough frosting to frost 12 cupcakes with a piping bag and star tip or fill and frost a 2 layer 9"round cake.
  • This is the perfect frosting to go on top of lemon poppyseed cake.
  • Add milk as needed: If you find that your frosting is too thick, add a little bit of milk (one tablespoon at a time) until it reaches the desired consistency. If it's too thin, add more powdered sugar.
  • Add more lemon flavor: If you enjoy more lemon flavor, add a bit more zest or a few drops of lemon flavor extract.
