Preparation
Filling
Step 1
Heat oven to 350°. Toss blackberries, cherries, sugar, flour, lemon juice, marjoram, vanilla, cinnamon, and salt in a large bowl. Transfer to a shallow 3-quart baking dish.
Biscuit Topping and Assembly
Step 2
Pulse flour, baking powder, salt, and 1 Tbsp. sugar in a food processor to combine. Add butter and pulse until the texture of coarse meal. Transfer mixture to a large bowl. Using a spoon, mix in buttermilk, then gently knead a few times until dough comes together. Drop mounds of biscuit over filling, brush with egg, and sprinkle with remaining 1 Tbsp. sugar.
Step 3
Place cobbler on a baking sheet and bake, tenting with foil if topping becomes too dark before filling is done, until filling is bubbling and topping is golden brown, 35–40 minutes. Transfer to a wire rack and let cool slightly.
Step 4
Just before serving, whisk cream, sour cream, honey, and powdered sugar in a medium bowl until soft peaks form.
Step 5
Serve cobbler topped with whipped cream mixture.
