Mix the flour, sugar and baking powder together in a medium sized mixing bowl.
Add the butter or margarine, and mix with your hands, breaking up the butter into small pieces while incorporating it into the flour mixture. The mixture should look like coarse crumbs when you are done.
Measure the milk in a glass measuring cup, crack open the egg, add it to the milk, and beat the egg and milk together.
Add the liquid to the flour/butter mixture and stir until just moistened. The mixture will be lumpy.
Spray the sides and bottom of an 8” or 9” round cake pan. Pour the batter into the pan, and bake at 450 degrees for 15-18 minutes.
Cut the cake into 8 servings, top with strawberries and whipped topping or ice cream.
