Include instructions for making the strawberry filling, dense pastry dough, toaster-style frosting, and assembly and baking steps. Emphasize the tips for achieving a store-bought texture: do not overmix dough, use less liquid for denser dough, roll dough thicker than pie crust, keep filling thick, and cool pastries fully before frosting."
