Preheat the oven to 350°F, and grease a mini loaf pan well.
Add the flour, sour cream, eggs, vanilla, baking powder, sugar, and butter to a mixing bowl and blend until smooth.
Fold in the strawberries.
Spread the mixture into the prepared mini loaf pan.
Bake for 35-40 minutes or until the pound cake loaf is cooked through completely.
Let cool to room temperature before slicing to serve.
Notes
Gently fold the diced strawberries into the batter. Doing this carefully ensures that they are distributed evenly throughout without breaking them down too much or causing them to sink to the bottom during baking.
Avoid over mixing the batter because it can produce a dense, tough texture. When you're combining the ingredients, mix until they are just incorporated.
Ensure the cake has cooled completely before slicing. Cooling allows the strawberry cake to firm up so it slices easily without crumbling.
