Preheat your oven to 350°F (175°C) and prepare a 9-inch loaf pan by greasing and flouring it.

In a large mixing bowl, combine the softened unsalted butter and granulated sugar, beating them together until light and fluffy, about 3-4 minutes.

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

Stir in the sour cream and vanilla extract until well-combined.

In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.

Gradually add the dry mixture to the wet mixture, stirring gently just until no flour pockets remain.

Gently fold in the hulled and sliced strawberries.

Carefully pour the cake batter into the prepared loaf pan, smoothing the top for an even bake.

Place the pan in your preheated oven and bake for 50-60 minutes.

Once baked, allow the cake to cool in the pan for about 20 minutes before transferring it to a wire rack to cool completely.
