Follow these simple steps to create your delicious Blueberry Cupcakes:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a medium bowl, combine the flour, baking powder, baking soda, and salt. Whisk to combine.
3. Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract until well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with buttermilk. Mix until just combined.
6. Fold in Blueberries: Gently fold in the fresh blueberries, being careful not to overmix to keep the batter fluffy.
7. Fill Muffin Tin: Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
8. Bake: Place in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and allow the cupcakes to cool in the tin for 10 minutes. Then, transfer them to a wire rack to cool completely.
10. Prepare Frosting: In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth.
11. Frost Cupcakes: Once the cupcakes are completely cool, frost them with the prepared icing and top with additional blueberries for garnish.
