RHUBARB SHORTCAKES

Steps:

• For roasted rhubarb:
• Preheat oven to 350°F. Combine rhubarb, sugar, and wine in a medium baking dish or ovenproof skillet. Scrape in seeds from vanilla bean; add bean and toss to combine.
• Roast until rhubarb is very tender and juices are syrupy, 30-40 minutes, depending on thickness of stalks. Let cool. Discard vanilla bean.
• For biscuits and assembly:
• Preheat oven to 375°F. Whisk cake flour, baking powder, sugar, salt, and 1 cup all-purpose flour in a medium bowl to combine. Add 1 1/2 cups cream; gently mix just until dough holds together.
• Transfer dough to a lightly floured surface and form into a 9x6" rectangle about 1" thick. Cut dough in half lengthwise, then cut crosswise 3 times to form 8 rectangular biscuits.
• Arrange biscuits on a parchment paper- lined baking sheet, spacing 1" apart. Brush tops and sides of biscuits with butter. Bake until golden brown, 18-20 minutes. Transfer to a wire rack; let cool (biscuits can be served warm or at room temperature).
• Beat remaining 1 1/2 cups cream in a medium bowl until soft peaks form. Split biscuits and brush cut sides with remaining melted butter. Fill biscuits with roasted rhubarb and serve with whipped cream.
• DO AHEAD: Rhubarb filling can be made 5 days ahead. Let cool, then cover and chill. Reheat slightly before serving. Biscuits can be made 1 day ahead. Let cool completely and store airtight at room temperature.
