Preheat the oven to 350°F (175°C). Grease and flour a baking pan.

In a mixing bowl, cream together the softened butter and sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, combine the flour, baking powder, and salt. Gradually add to the creamed mixture alternately with milk, mixing until just combined.

Fold in the sliced strawberries.

Pour the batter into the prepared baking pan and smooth the top.

Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

In a mixing bowl, beat the softened butter until creamy.

Gradually add the powdered sugar and mix until well combined.

Add the vanilla extract and milk, mixing until the frosting is smooth and spreadable.

Once the cake is completely cool, spread the frosting evenly over the top.

Decorate with additional sliced strawberries if desired.
