Instructions:
1. Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper for easy removal.

2. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

3. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. You can use an electric mixer or do it by hand with a wooden spoon.

4. Beat in the eggs, one at a time, ensuring each egg is fully incorporated before adding the next one. Scrape down the sides of the bowl as needed.

5. Add half of the flour mixture to the butter and sugar mixture. Mix until just combined. Then, pour in the milk and vanilla extract, and mix again. Finally, add the remaining flour mixture and mix until the batter is smooth.

6. Gently fold in the diced strawberries, being careful not to overmix. The strawberries should be evenly distributed throughout the batter.

7. Pour the batter into the prepared loaf pan, spreading it out evenly.
