01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, and salt until well combined.
03 - Cut in the cold butter with a pastry blender or fingers until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk together milk, egg, and vanilla until fully incorporated.
05 - Pour the wet ingredients into the dry ingredients. Mix gently until just combined, being careful not to overmix.
06 - Scoop 6 equal mounds of dough onto the prepared baking sheet, spacing evenly for baking.
07 - Bake for 15 to 18 minutes until golden brown. Remove from oven and let cool completely.
08 - Combine strawberries, sugar, and lemon juice in a bowl. Toss to coat evenly and set aside for at least 15 minutes to allow flavors to meld.
09 - In a chilled bowl, whip the cream, powdered sugar, and vanilla with an electric mixer until soft peaks form.
10 - Crumble one shortcake into the bottom of each serving cup. Top with a layer of macerated strawberries, then a layer of whipped cream. Repeat layers as desired, finishing with whipped cream and a strawberry garnish.
