01 - Combine strawberries, sugar, and lemon juice in a medium bowl. Stir gently to coat. Cover and let macerate at room temperature for at least 20 minutes, allowing the berries to release their juices and soften.
02 - Preheat oven to 425°F. Line a baking sheet with parchment paper and set aside.
03 - In a large bowl, whisk together flour, baking powder, baking soda, salt, and sugar until evenly combined.
04 - Add cold cubed butter to the flour mixture. Use a pastry cutter or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
05 - Pour cold buttermilk into the bowl and stir gently until just combined. Do not overmix—some dry spots are acceptable.
06 - Turn dough onto a lightly floured surface. Gently pat into a 1-inch thick rectangle. Fold dough in half and pat out again. Repeat this folding process twice to create flaky layers.
07 - Cut out 6 rounds using a 2½-inch biscuit cutter, pressing straight down without twisting. Place on prepared baking sheet. Brush tops lightly with additional buttermilk.
08 - Bake for 15–18 minutes until tops are golden brown. Transfer to a wire rack and let cool slightly.
09 - In a chilled bowl, beat heavy cream with powdered sugar and vanilla extract using an electric mixer or whisk until soft peaks form.
10 - Split biscuits in half horizontally. Place bottom halves on serving plates, spoon strawberries and juices generously over each, add a dollop of whipped cream, and top with biscuit crowns. Serve immediately while biscuits are still slightly warm.
