01 - Combine sliced strawberries, sugar, and lemon juice in a large bowl. Toss gently to coat evenly. Set aside for at least 30 minutes, allowing the strawberries to release their juices and create a syrupy consistency.
02 - Preheat oven to 425°F. Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
03 - Whisk together flour, sugar, baking powder, and salt in a large mixing bowl until thoroughly combined.
04 - Add cold cubed butter to the flour mixture. Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
05 - Pour cold milk and vanilla extract into the flour mixture. Stir gently with a spatula just until the dough comes together—do not overmix. The dough should be slightly sticky but manageable.
06 - Turn the dough onto a lightly floured surface. Gently pat the dough to 1-inch thickness. Using a 2 3/4-inch biscuit cutter, cut out 6 rounds, pressing straight down without twisting. Gather scraps and recut if necessary.
07 - Arrange biscuits on the prepared baking sheet, leaving 2 inches between each. Bake for 15 to 18 minutes until tops are golden brown. Cool completely on a wire rack.
08 - In a chilled bowl, beat heavy cream with an electric mixer or whisk until soft peaks begin to form. Add powdered sugar and vanilla extract. Continue beating until stiff peaks form, being careful not to overbeat.
09 - Slice each cooled biscuit horizontally in half. 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 cream if desired.
