1. Prepare the Shortcakes:

• Preheat oven to 400°F (200°C). In a large bowl, whisk together flour, sugar, baking powder, and salt. Add cold butter and cut it into the flour mixture until it resembles coarse crumbs.
• Stir in heavy cream and vanilla extract until the dough comes together. Turn the dough out onto a floured surface and knead gently. Pat into a 1-inch thick circle and cut out 6 rounds using a biscuit cutter.
• Place the shortcakes on a baking sheet lined with parchment paper. Brush the tops with beaten egg. Bake for 15-18 minutes or until golden brown. Let cool on a wire rack.

2. Prepare the Strawberries:

• In a medium bowl, combine sliced strawberries, sugar, and chopped basil. Toss gently and let sit for at least 15 minutes to macerate.

3. Make the Balsamic Glaze:

• In a small saucepan, combine balsamic vinegar and honey. Bring to a simmer over medium heat and cook until reduced by half, about 10 minutes. Set aside to cool.

4. Whip the Cream:

• In a large bowl, beat the heavy cream, powdered sugar, and vanilla extract until soft peaks form. Set aside.

5. Assemble the Shortcakes:

• Slice the cooled shortcakes in half horizontally. Spoon the macerated strawberries over the bottom half of each shortcake. Add a dollop of whipped cream and drizzle with balsamic glaze. Place the top half of the shortcake on top and serve immediately.
