Add 2⅓ cup bisquick, ½ cup milk, 3 Tbsp sugar, and 3 Tbsp melted butter in a medium bowl. Mix until blended.
Turn dough out onto a floured surface and shape into a rectangle. Use a knife or bench scraper to divide dough into 8 approximately even biscuits. (You can always make smaller or larger portions)
Place onto cookie sheet 2” apart and bake at 425° for 10-12 minutes or until lightly browned. Allow to cool before serving.
Assemble the strawberry shortcake when ready to serve. Slice shortcakes in half horizontally. Spoon desired amount of both whipped cream and strawberries over bottom half of shortcake, then cover with the top half.
Spoon additional strawberries over top and serve fresh.
