Preheat your oven to 350°F (175°C) and grease a loaf pan.

In a bowl, combine flour, baking powder, baking soda, and salt.

In a separate large bowl, cream the butter and sugar until light and fluffy.

Add eggs one at a time, mixing well after each addition.

Stir in the vanilla extract and mix until combined.

Add the dry ingredients alternately with the buttermilk, starting and ending with the dry ingredients.

Gently fold in the sliced strawberries, being careful not to overmix.

Pour the batter into the prepared loaf pan.

Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean.

Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
