Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, sugar, baking powder, and salt.
Cut in the shortening by using a pastry blender until the mixture resembles crumbs (a few slightly larger bits are okay).
Pour in the milk and stir with a fork until a soft dough forms. It should feel tender and a little sticky, not dry.
Turn the dough onto a lightly floured surface and knead gently 8–10 times, just until it comes together.
Pat or roll the dough to about ¾-inch thick. Cut with a floured 2½-inch cutter. Press straight down; don’t twist.
Place biscuits ½ to 1 inch apart on the baking sheet. Lightly rub tops with butter.
Bake 14–16 minutes, until lightly golden.
Cut strawberries into small pieces. Toss with ½ tbsp sugar and let sit 10–15 minutes so they get juicy.
Split a biscuit in half and layer strawberries.
Add a big dollop of whipped cream right on top. (And yes—use dairy-free whipped topping if needed.)
