Ingredients

Lemon Cake

  • 1 ½ cups (187.5 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • 1 teaspoon baking soda
  • ½ teaspoon kosher salt
  • lemon zest, from 1 large lemon (about 1 ½ teaspoons)
  • ¼ cup freshly squeezed lemon juice, about 1 large lemon
  • 1 teaspoon distilled white vinegar
  • 1 cup (250 g) water
  • cup (73 g) vegetable oil

Lemon Buttercream

  • ½ cup (1 stick / 113 g) unsalted butter, room temperature
  • 1 ¾ cups (219 g) confectioners' sugar
  • 1 pinch kosher salt
  • ½ medium lemon, juiced (about 1 tablespoon lemon juice)
  • 1 teaspoon lemon zest, about one lemon
  • ½ teaspoon vanilla extract

Instructions

  • Preheat the oven to 350°F. Spray an 8x8-inch baking dish with nonstick cooking spray.

Lemon Cake

  • In a large bowl, combine flour, sugar, baking soda, salt, and lemon zest. Whisk to combine.
  • To the flour mixture, add lemon juice, vinegar, water, and oil. Whisk until ingredients are fully combined.
  • Pour the cake batter into the prepared pan. Bake for 35-37 minutes. The cake is done when an inserted toothpick is inserted and comes out clean with a few crumbs, but no wet batter. Let the cake cool while you prepare the frosting.

Lemon Buttercream

  • Using a handheld mixer, beat the butter, sugar, and salt on medium speed until well combined.
  • Add lemon juice, lemon zest, and vanilla. Continue to beat for another 3 to 5 minutes, or until creamy.
  • Spread the buttercream over the cooled cake.
