01 - Preheat the oven to 400°F. Line a muffin tin with paper liners or lightly grease with butter.
02 - In a large bowl, whisk together the flour, sugar, baking powder, and salt until thoroughly combined.
03 - Add the cold butter and cut it in using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
04 - In a small bowl, whisk together milk, egg, and vanilla. Pour into the flour mixture and stir just until combined; do not overmix.
05 - Divide the dough evenly among 6 muffin cups. Bake for 16–18 minutes, or until lightly golden. Let cool completely.
06 - Toss the sliced strawberries with sugar and lemon juice in a bowl. Let sit for at least 15 minutes to macerate.
07 - Beat the chilled cream, powdered sugar, and vanilla with an electric mixer on medium-high speed until soft peaks form.
08 - Slice each shortcake in half horizontally. Layer the bottom half with macerated strawberries and a dollop of whipped cream. Top with the other half and add more strawberries and cream. Serve immediately.
