Ingredients
- 1 cup (2 sticks) unsalted butter, room temperature, plus more for pans
- 2.5 cups all-purpose flour (spooned and leveled), plus more for pans
- 0.5 teaspoon baking powder
- 0.5 teaspoon baking soda
- 1 teaspoon salt
- 1 tablespoon lemon zest
- 2 cups sugar
- 2 large eggs plus 3 large egg yolks
- 0.25 cup plus 2 tablespoons fresh lemon juice
- 1 cup low-fat buttermilk
- 1 lemon, thinly sliced and seeded

Instructions
- 1Preheat oven, prepare cake pans, and combine dry ingredients: Preheat oven to 350 degrees. Butter and flour two 8-by-2-inch cake pans, tapping out excess flour. In a medium bowl, whisk flour, baking powder, baking soda, salt, and lemon zest.
- 2Cream butter and sugar: In a large bowl, using an electric mixer, beat butter and 1 1/2 cups sugar until light and fluffy.
- 3Add eggs, then dry ingredients and buttermilk: With mixer on low, beat in eggs and yolks, one at a time. Beat in 2 tablespoons lemon juice. Alternately beat in flour mixture and buttermilk beginning and ending with flour mixture; mix just until combined.
- 4Divide batter between cake pans and bake: Divide batter between cake pans; smooth tops. Bake until cakes pull away from sides of pans, 32 to 35 minutes.
- 5Let cakes cool and remove from pans: Let cool in pans 10 minutes. Run a knife around edges of pans and invert cakes onto a wire rack.
- 6Make simple syrup: While cakes are baking, bring remaining 1/2 cup sugar and 1/2 cup water to a boil in a saucepan.
- 7Add lemon slices to the syrup: Add the lemon slices and simmer for 25 minutes.
- 8Remove lemon slices from syrup: Using a slotted spoon, transfer lemon slices to a waxed-paper-lined plate.
- 9Add lemon juice to syrup: Stir remaining 1/4 cup fresh lemon juice into syrup.
- 10Brush cakes with lemon syrup: Using a toothpick, poke holes in warm cakes on rack. Brush with lemon syrup. Let cool completely.
- 11Make frosting, assemble cake, and frost: Prepare Whipped Frosting , substituting 2 tablespoons fresh lemon juice for vanilla extract. Frost cooled cakes and top with the candied lemon slices.
