Lemon Cupcakes: 

  • 190g all purpose flour
  • 33g cornstarch
  • 1 tsp baking powder
  • ¼ tsp Morton’s Kosher Salt
  • 115g unsalted butter, melted (about 1 stick)
  • 150g superfine sugar
  • 60g whole milk
  • 2 eggs
  • 2 medium lemons (using the zest and the juice)
  • 1 tsp vanilla extract

Lemon Buttercream: 

  • 260g of powdered sugar
  • Zest from 1 medium lemon
  • 1 tsp lemon juice
  • 115g of butter, room temperature (about 1 stick)
  • 1/2 tsp vanilla
  • 2 tbsp whole milk



  • Preheat the oven to 350ºF, convection.
  • Prepare a 8×8” glass baking pan by greasing and lining it
  • Prepare your work space by measuring out all the ingredients.


  • In a medium sized bowl, whisk together the flour, cornstarch, baking powder and salt. Place to the side.
  • In a large bowl, combine the melted butter and sugar. The mixture will look almost like apple sauce when fully combined.
  • Add in the whole milk and eggs, whisk to combine.
  • Add the lemon zest, juice, and vanilla to the bowl and whisk again.
  • Gradually add in your dry ingredient mixture and combine well using a rubber spatula. Stir until the batter is smooth.
  • Spoon the batter into the lined baking pan and spread using a spatula into an even layer.
  • Bake for 20 minutes or until you can stick a toothpick in the center and they come out clean.
  • While the cake completely cools, prepare your lemon buttercream frosting.


  • Cream the butter until it is light and fluffy – usually takes 3 minutes.
  • Gradually add in the powdered sugar, beating between additions.
  • Then, slowly add in the lemon zest, lemon juice and vanilla extract.
  • Finally, add in the milk and beat for another 3 minutes.
  • Spread onto the cake using a spatula or your favorite piping tips!
  • Sprinkle a little more lemon zest on top or any other decorations you’d like!
  • Dig in and enjoy!
