Preheat oven to 425°F (220°C).
Combine flour, baking powder, baking soda, salt, and sugar in a large bowl.
Cut butter into flour mix until it resembles coarse breadcrumbs. Mix in strawberries.
In a small bowl, combine milk and sour cream. Pour into strawberry mixture and blend with a spatula until a sticky dough forms.
Turn onto a lightly floured surface and roll out to ½-inch thickness. Cut dough with 3-inch round cutter.
Bake in oven for 15 minutes or until golden brown.
