Preheat your oven to 350°F and lightly grease a 9x9-inch baking dish.
In a saucepan, melt 1/4 cup butter and stir in 1/2 cup sugar until combined.
Pour the mixture into the prepared baking dish, then arrange the sliced strawberries evenly over the top.
In a large mixing bowl, use an electric mixer to cream together the softened butter and remaining sugar until light and fluffy.
Add the eggs and vanilla extract, mixing until smooth.
Pour in the milk and mix until combined.
In a separate bowl, whisk together the dry ingredients.
Gradually add the dry ingredients to the wet ingredients, mixing just until a smooth batter forms.
Carefully spoon and spread the batter over the strawberries, being careful not to disturb the fruit layer.
Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool for about 10 minutes before serving.
Finish with a dusting of powdered sugar or a dollop of whipped topping, if desired.
