Creating Blueberry Cake with Lemon Cream Cheese Frosting is a straightforward process if you follow these steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
3. Cream Butter and Sugar: In another large mixing bowl, use an electric mixer to cream the softened butter and granulated sugar until light and fluffy.
4. Add Eggs: Beat in the eggs one at a time, ensuring each is well incorporated before adding the next.
5. Incorporate Buttermilk: Mix in the buttermilk and vanilla extract, combining everything until smooth.
6. Combine Mixtures: Gradually add the dry mixture to the wet mixture, mixing just until combined. Be careful not to overmix.
7. Fold in Blueberries: Gently fold the fresh blueberries into the batter.
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. Use a toothpick to check for doneness; it should come out clean.
10. Cool the Cakes: Once baked, remove them from the oven. Let the cakes cool in their pans for 15 minutes before transferring them to wire racks to cool completely.
11. Prepare the Frosting: In a large bowl, beat the softened cream cheese and butter together until creamy. Gradually add the powdered sugar, lemon juice, lemon zest, and salt, mixing until smooth and fluffy.
12. Frost the Cake: Once the cakes have cooled completely, spread a layer of frosting on top of one cake layer. Place the second layer on top and frost the top and sides of the cake as desired.

By following these steps, you’ll create a stunning and delicious Blueberry Cake with Lemon Cream Cheese Frosting that will blow everyone away!
