- Prepare the Baking Pan: Preheat oven to 350°F (175°C). Grease and flour a 12-cup bundt pan, making sure to coat all the nooks and crannies. Alternatively, you can use two 9-inch round cake pans.
- Mix the Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. Set aside.
- Cream Butter and Sugar: In a large mixing bowl, use an electric mixer to beat the butter on medium speed until creamy, about 1 minute. Gradually add the sugar and continue beating until light and fluffy, about 3-4 minutes. Scrape down the sides of the bowl as needed.
- Add Eggs and Flavorings: Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract, lemon zest, and lemon juice until combined.
- Combine Wet and Dry Ingredients: With the mixer on low speed, add the dry ingredients in three additions, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix just until combined after each addition, being careful not to overmix.
- Bake the Cake: Pour the batter into the prepared pan(s) and smooth the top. Bake for 45-50 minutes for a bundt cake (or 25-30 minutes for round cakes), or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Prepare the Lemon Syrup: While the cake is baking, combine the lemon juice and sugar in a small saucepan over medium heat. Stir until the sugar dissolves completely, then remove from heat.
- Apply the Syrup: Allow the cake to cool in the pan for 10 minutes, then invert onto a wire rack placed over a baking sheet. While the cake is still warm, poke holes all over the top with a skewer or toothpick. Slowly brush or pour the warm lemon syrup over the cake, allowing it to soak in.
- Make the Lemon Glaze: In a medium bowl, whisk together the powdered sugar, lemon juice, lemon zest, and melted butter until smooth. Add more lemon juice or powdered sugar as needed to achieve a pourable consistency.
- Finish the Cake: Once the cake has cooled completely, drizzle the glaze over the top, allowing it to run down the sides. Let the glaze set for about 20 minutes before serving.
Serving Suggestions:
Serve slices of this bright lemon cake with fresh berries, a dollop of whipped cream, or a scoop of vanilla ice cream. For a beautiful presentation, garnish with candied lemon slices, fresh mint leaves, or edible flowers. A light dusting of powdered sugar just before serving adds an elegant touch.
