Making the Lemon Blueberry Cake is an enjoyable process that can be easily followed. Here are the steps to ensure your cake turns out perfectly:

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined.
3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar until light and fluffy using an electric mixer.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition. Ensure the mixture is smooth.
5. Incorporate Lemon: Mix in the lemon zest, lemon juice, and vanilla extract until fully combined.
6. Combine Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with buttermilk. Start and end with the flour mixture, mixing until just combined.
7. Fold in Blueberries: Gently fold the blueberries into the batter, being careful not to overmix.
8. Divide Batter: Pour the batter evenly into the prepared cake pans.
9. Bake: Place the pans in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Remove the cakes from the oven and allow them to cool in the pans for about 15-20 minutes. Then transfer to a wire rack to cool completely.
11. Frosting (Optional): You may choose to frost the cake with a lemon glaze or cream cheese frosting for added flavor.

These steps will guide you effortlessly to create a stunning Lemon Blueberry Cake that everyone will adore.
