Ingredients
For the Cake
- 2 cups all-purpose flour
- 1½ teaspoons baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 tablespoon finely grated lemon zest
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract
- 1 cup buttermilk
For the Lemon Glaze
- 1 cup powdered sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon finely grated lemon zest
Instructions
- Preheat the oven to 350°F (175°C). Grease and lightly flour a 9-inch round cake pan.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
- In a large bowl, beat the softened butter and sugar until pale and creamy.
- Add the eggs one at a time, beating well after each addition.
- Mix in the lemon zest, lemon juice, and vanilla extract.
- Gradually add the dry ingredients, alternating with the buttermilk, beginning and ending with the flour mixture.
- Mix just until combined, taking care not to overmix the batter.
- Pour the batter into the prepared cake pan and gently smooth the top.
- Bake for 35–40 minutes, or until golden and a skewer inserted into the center comes out clean.
- Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack.
- To make the glaze, whisk the powdered sugar, lemon juice, and lemon zest together until smooth.
- Drizzle the glaze over the completely cooled cake and allow it to set before slicing.
Cooking Tips
- Use freshly squeezed lemon juice and fresh zest for the brightest flavor.
- Bring the eggs and buttermilk close to room temperature before mixing for a smoother batter.
- Do not overmix after adding the flour, as this can make the cake less tender.
- For a more rustic appearance, drizzle the glaze loosely over the cake rather than covering the entire surface.
Serving Suggestions
Serve this cake with a pot of Irish tea or freshly brewed coffee. It is delicious on its own or accompanied by fresh berries, lightly whipped cream, or a spoonful of lemon curd for an extra burst of citrus flavor.
