Preheat oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.

In a large bowl, cream together butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla.

In a separate bowl, whisk together flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Gently fold in the sliced strawberries.

Pour batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.

In a large bowl, beat together cream cheese and butter until smooth. Gradually add powdered sugar, beating until light and fluffy. Stir in vanilla.

Frost the cooled cake and decorate with fresh strawberries, if desired.
