I have made this so many times and it never fails. 

INGREDIENTS

1 1/2 cups flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
6 tablespoons butter, softened
1 cup + 2 tablespoons sugar (divided)
Zest of one lemon
1 egg
1 teaspoon vanilla
1/2 cup milk
1 pound of strawberries

DIRECTIONS

Preheat oven to 350 degrees F. Butter a deep pie pan.

In medium blow mix together flour, baking powder and salt, and set aside.

Using electric mixer, cream butter, sugar, until fluffy. Add egg, vanilla, and zest until well combined. Slowly add dry ingredients alternating with milk and beat on low until smooth.

Scoop batter (it will be thick) into pan and smooth. Arrange strawberries (hulled and halved) on top with the cut side down.

Reduce oven to 325 degrees and cook for about an hour.  Let cool.
