Instructions:

Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Thoroughly grease and flour a 10-inch Bundt pan to ensure easy cake removal.
Mix Dry Ingredients: In a medium bowl, sift together flour, baking powder, baking soda, and salt. Set aside.
Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and sugar until light and fluffy, approximately 4-5 minutes using an electric mixer.
Incorporate Eggs and Flavors: Add eggs one at a time, beating well after each addition. Mix in the lemon zest, lemon juice, and vanilla extract.
Combine with Dry Ingredients and Buttermilk: Gradually add the dry ingredients and buttermilk to the butter mixture, alternating between the two and beginning and ending with the dry ingredients. Mix until just combined.
Bake the Cake: Pour the batter into the prepared Bundt pan and smooth the top with a spatula. Bake for 45 to 50 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Cool and Glaze: Allow the cake to cool in the pan for about 10 minutes, then invert onto a wire rack to cool completely. For the glaze, whisk together powdered sugar and lemon juice until smooth. Drizzle over the cooled cake.
Serve: Once the glaze has set, the cake is ready to be served. Garnish with additional lemon zest if desired.
