Ingredients

Lemon Cake

  • cups (187.5 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • ½ teaspoon kosher salt
  • 1 teaspoon baking soda
  • 1 tablespoon lemon zest
  • ½ cup freshly squeezed lemon juice, about 2 lemons
  • 1 teaspoon distilled white vinegar
  • cup (73 g) vegetable oil
  • 1 cup (250 g) water

Lemon Buttercream

  • 1 cup (2 sticks / 227 g) unsalted butter, room temperature
  • cups (437.5 g) confectioners' sugar
  • teaspoon kosher salt
  • 1 medium lemon, juiced (about ¼ cup lemon juice)
  • 1 teaspoon vanilla extract
  • teaspoons lemon zest, about one lemon

Instructions

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

Lemon Cake

  • In a large bowl, combine flour, sugar, salt, baking soda, and lemon zest. Whisk to combine.
  • To the flour mixture, add lemon juice, vinegar, oil, and water. Stir using a spatula or whisk until ingredients are fully combined.
  • Pour the cake batter into the prepared pan. Bake for 25-30 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 and vanilla. Continue to beat for another 3 to 5 minutes, or until creamy.
  • Fold in the lemon zest.
  • Spread the buttercream over the cooled cake.
