Preheat & Prepare Pan: Preheat oven to 350°F (175°C). Grease and flour your Bundt pan thoroughly.
Mix Dry Ingredients: In a bowl, whisk together flour, baking powder, baking soda, and salt.
Cream Butter & Sugar: In a large bowl, beat softened butter and sugar until light and fluffy (about 2–3 minutes).
Add Eggs & Flavor: Beat in eggs one at a time, then mix in sour cream, milk, lemon zest, lemon juice, and vanilla extract until smooth.
Combine & Pour: Gradually add dry ingredients to wet, mixing just until combined. Pour batter evenly into the prepared Bundt pan.
Bake: Bake for 40–45 minutes or until a toothpick inserted comes out clean.
Cool: Let cake cool in the pan for 10–15 minutes, then invert onto a wire rack to cool completely.
Make Glaze: In a small bowl, whisk together powdered sugar and lemon juice until smooth.
Glaze the Cake: Once fully cooled, drizzle glaze over the top and let it set before slicing.
