Equipment

  • Cupcake tins Regular or mini
  • Cupcake liners
  • Stand Mixer or hand mixer
  • Mixing bowl
  • Spatula

Ingredients

For cupcakes:

  • 1 1/4 cups all-purpose flour
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 tablespoon poppy seeds
  • 1/3 cup vegetable oil
  • 1 cup granulated sugar
  • Zest of one lemon organic preferred
  • 3 large eggs room temperature
  • 1/2 cup full-fat sour cream room temperature
  • 1 teaspoon vanilla extract
  • 1 tablespoon fresh lemon juice

For the frosting:

  • 3/4 cup butter room temperature
  • Zest of 1/2 lemon organic preferred
  • 2 cups powdered sugar sifted
  • 1 teaspoon vanilla extract
  • 1/2 tablespoon fresh lemon juice
  • Poppy seeds for decoration
  • 3 lemon slices cut into quarters

Instructions

  • Preheat the oven to 320° F. Fill two cupcake trays with 15 liners total.

For the cupcakes:

  • Sift together the dry ingredients, except the sugar and set aside.
  • In a mixing bowl, combine the vegetable oil with the sugar and lemon zest. Beat until fluffy, about 1 minute.
  • Add the eggs, one at a time, until fully incorporated.
  • With the mixer on low speed, slowly add the dry ingredients to the bowl and mix, scraping down the sides, until fully incorporated.
  • Add the sour cream, vanilla extract and lemon juice. Mix just until combined. Do not overmix.
  • Divide the batter among the cupcake liners, filling each about 2/3 full.
  • Bake for 20-22 minutes, until a toothpick inserted comes out clean.
  • Remove the cupcakes from the oven. Cool for 5 minutes on a wire rack, then remove the cupcakes from the tray and cool completely.

For the frosting:

  • To make the buttercream frosting, combine the butter and lemon juice in a mixing bowl. Beat until fluffy, about 4 minutes.
  • Add the powdered sugar, a little at a time, until fully incorporated.
  • Then add the vanilla extract and lemon juice until fully incorporated.
  • Scrape down the sides of the bowl and mix the frosting for 1 minute.
  • Transfer the frosting to a piping bag with a 1M tip. Frost the cupcakes once they are cooled.
  • Decorate with the poppy seeds and lemon slices.

Notes

  • Ensure that your eggs and sour cream are at room temperature. This helps achieve a smoother and more even batter.
  • When zesting lemons, use a fine grater or a microplane for the best results. Avoid grating the white pith, which can be bitter.
  • When combining the wet and dry ingredients, mix just until they're incorporated. Overmixing can lead to dense cupcakes.
  • Make sure the cupcakes are completely cooled before frosting. Warm cupcakes can cause the frosting to melt.
