Ingredients

  • 1 ¼ cup (200g) granulated sugar
  • Zest of 1 large lemon
  • 1 Tbsp lemon juice
  • ½ cup sour cream room temp
  • ½ cup milk
  • ¼ cup vegetable oil
  • 1 large egg room temp
  • 1 tsp lemon extract
  • 1 tsp vanilla extract
  • 1 cup cake flour
  • ½ cup AP flour
  • 1 ½ tsp baking powder
  • ½ tsp salt
  • 1 Tbsp poppy seeds

Method

  1. Preheat your oven to 350°F / 175°C and line your cupcake pan with cupcake liners.
  2. Add the 1 1/4 cup granulated sugar and 1 Tbsp lemon zest to a large bowl and using your fingertips, massage the zest into the sugar to help release all the lemon oils. This is important. Set aside.
  3. In a large bowl, whisk together sour cream, milk, vegetable oil, 1 egg, lemon extract, lemon juice, and vanilla extract. Mix well.
  4. Whisk in cake flour and all-purpose flour, lemon sugar, poppy seeds, baking powder, and salt into the wet ingredients. Mix until just combined and not lumpy.
  5. Fill the cupcake liners 3/4 full and bake for 18-20 minutes or until a toothpick comes out clean.
  6. While the cupcakes are baking make your frosting: In a medium bowl beat 1/4 cup of unsalted butter and 1/4 cup of cream cheese on a high speed for 30 seconds with a hand mixer until smooth. Add in 1 Tbsp lemon zest, vanilla extract, and salt. Beat on low until the ingredients are combined.
  7. Gradually mix in 2 cups of powdered sugar and fresh lemon juice. Add to piping bag.
  8. Remove the cupcakes from the oven and let cool then use a teaspoon or cupcake tool to remove 1 inch of the center of the cupcake. Fill with lemon curd and pipe on frosting and dust with a sprinkle of poppy seeds.
