01 - Combine sliced strawberries, sugar, and lemon juice in a large bowl. Toss gently to coat evenly. Set aside for at least 30 minutes to allow strawberries to release their juices and become syrupy.
02 - Preheat oven to 425°F. Line a baking sheet with parchment paper and set aside.
03 - In a large mixing bowl, whisk together flour, sugar, baking powder, and salt until well combined.
04 - Add cold cubed butter to the flour mixture. Use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
05 - Pour in cold milk and vanilla extract. Stir gently with a spatula just until the dough comes together—do not overmix. The dough should be slightly shaggy.
06 - Turn dough onto a lightly floured surface. Gently pat the dough to about 1 inch thickness. Using a 2 3/4 inch biscuit cutter, cut out 6 rounds without twisting the cutter. Place on prepared baking sheet.
07 - Bake for 15 to 18 minutes until tops are golden brown. Transfer to a wire rack and let cool completely.
08 - In a chilled bowl, beat heavy whipping cream, powdered sugar, and vanilla extract with a whisk or electric mixer until soft peaks form. Do not overbeat.
09 - Slice each cooled biscuit in half horizontally. Place the bottom half on a serving plate. Spoon macerated strawberries and their juices over the biscuit. Top with a generous dollop of whipped cream. Cover with the biscuit top. Add additional strawberries and whipped cream if desired.
