Making Lemon Blueberry Cake is a fun and straightforward process. Follow these easy steps to achieve a delicious result:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease two 9-inch round cake pans, lining the bottoms with parchment paper for easy removal.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt until combined.
3. Cream Butter and Sugar: In another bowl, use a hand mixer or stand mixer to beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
4. Add Eggs and Flavorings: Add the eggs, one at a time, mixing well after each addition. Then include the vanilla extract and lemon zest, mixing until just combined.
5. Combine Wet Ingredients: In a separate bowl, combine the buttermilk and lemon juice.
6. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk mixture. Begin and end with the dry ingredients, mixing until just combined.
7. Fold in Blueberries: Gently fold the blueberries into the batter with a spatula, being careful not to overmix.
8. Divide Batter: Pour the batter evenly into the prepared cake pans.
9. Bake: Place both pans in the preheated oven and bake for 30-35 minutes. A toothpick inserted in the center should come out clean when done.
10. Cool: Once baked, remove the cakes from the oven and let them cool in their pans for about 15 minutes. Then, transfer them to wire racks to cool completely.
11. Frost and Assemble: Once completely cool, frost with your desired frosting (cream cheese frosting works wonderfully), and layer them on top of each other.

These steps will ensure that your Lemon Blueberry Cake is perfectly baked and ready to impress!
