Line a baking sheet with parchment paper. Preheat oven to 350°F (177°C).
Fold the sliced strawberries (4 cups) and 1/4 cup sugar in a mixing bowl; set aside.
Mix together Bisquick (2 ⅓ cups), milk (2/3 cup), 1/3 cup sugar, and butter (3 tablespoons) until it comes together in a soft dough.
Form 6 biscuits by dropping dough onto the prepared baking sheet. Sprinkle tops with coarse sugar (2-3 tablespoons), if using. Bake in preheated oven for 14-16 minutes, or until golden brown.
While the biscuits bake, make whipped cream (1/2 cup).
Assemble: Split biscuits, spoon strawberries and juice over bottom of biscuits, top with whipped cream, then top with biscuit top. Serve.
Notes
Cool Shortcakes: Cool the shortcakes before slicing them so the layer doesn’t compress.
Serrated Knife: Use a sawing motion with a serrated knife to cut the shortcakes.
Prepare Strawberries: After folding strawberries with sugar, allow them to sit for 20-30 minutes. As they sit, they will release their juices creating a sweet syrup. Don’t allow them to sit for too long or they will be limp and mushy. 45 minutes is generally the maximum amount of time I let them sit.
Other Fruit: This recipe is also delicious with the strawberries swapped out with peaches, blackberries, raspberries, or mixed berries.
