Make the Fresh Strawberry Topping by combining strawberries with sugar. Cover and set aside to thicken. Can be served at room temperature or chilled.
02 -
In a large bowl, whisk together 3 cups flour, 1/3 cup granulated sugar, 1 teaspoon kosher salt, and 2 tablespoons baking powder until well combined.
03 -
Chop the cold butter into small chunks. Add to the flour mixture and use a pastry cutter to incorporate until you have a crumbly mixture with pea-sized butter pieces.
04 -
In a separate container, whisk together the cold buttermilk and egg. Add this mixture to the flour and stir with a rubber spatula to create a shaggy dough. Some dry flour is acceptable at this stage.
05 -
With floured hands, knead the dough a few times in the bowl to incorporate any loose flour. If too dry to come together, add 1 tablespoon of cold buttermilk or ice water.
06 -
Turn the dough onto a floured surface and roll into a rectangle approximately 23x33 cm. Fold the dough in half, then in quarters, then once more to create layers. Pat or gently roll to a thickness of about 3 cm.
07 -
Using a floured 6.5 cm biscuit cutter, cut straight down without twisting. Re-roll scraps and repeat until all dough is used.
08 -
Place shortcakes in a buttered cast iron skillet or greased 23x23 cm square baking pan with sides, positioning them snugly together (touching or about 1 cm apart) to help them rise properly.
09 -
For best results, freeze the prepared shortcakes for 20 minutes while preheating the oven to 220°C for at least 20 minutes.
10 -
Just before baking, brush tops with buttermilk or heavy cream and sprinkle generously with sugar (preferably coarse raw sugar for texture).
11 -
Bake at 220°C for 18-22 minutes until deeply golden brown on top, firm around edges, and beginning to brown on bottoms. If tops brown too quickly, cover with foil for remaining bake time.
12 -
While shortcakes bake, beat heavy cream, powdered sugar, and vanilla on high speed for 2-5 minutes until thick with soft peaks that hold their shape. Refrigerate until ready to serve.

Split warm shortcakes horizontally, layer with strawberry topping and whipped cream, replace top half, then finish with additional strawberry topping and whipped cream.
