Creating this Lemon Blueberry Cake is simple if you follow these steps:

1. Preheat the 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. Set aside.
3. Cream Butter and Sugar: In another bowl, cream together the softened butter and sugar until light and fluffy. This usually takes about 3-5 minutes.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition. Incorporate the vanilla extract next.
5. Combine Wet Ingredients: In a separate bowl, combine buttermilk, lemon zest, and lemon juice.
6. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk mixture. Mix until just combined.
7. Fold in Blueberries: Gently fold in the fresh blueberries, being careful not to overmix.
8. Divide Batter: Evenly distribute the batter into the prepared cake pans and smooth out the tops.
9. Bake: Place the pans in the oven and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
10. Cool Down: Remove from the oven and let the cakes cool in their pans for 15-20 minutes. Then transfer them to wire racks to cool completely.
11. Prepare for Serving: Once cool, you may frost the cake, sprinkle with powdered sugar, or serve plain, depending on preference.

By following these straightforward steps, you’re bound to create a delightful Lemon Blueberry Cake that will impress everyone!
