1. Make the fruit filling. In a medium bowl, mash 1 cup of the raspberries with a fork. Add the sugar, vanilla, and remaining whole berries. Let sit at room temperature for 30 to 60 minutes for the berries to release their juices. May be prepared 1 day in advance and stored, refrigerated.
2. Preheat the oven to 400 degrees. Line a baking sheet with parchment paper.
3. Prepare the shortcakes. In a large bowl, whisk flour, cocoa, brown sugar, baking powder, baking soda, and salt. Using a pastry blender or a fork, cut butter into the dry ingredients until the mixture is crumbly and the size of small peas.
4. In a small bowl, combine instant coffee and hot water and stir until coffee is dissolved. Add milk and stir to combine. Make a well in the center of the flour mixture and pour in milk mixture. Mix with a fork until the dough is moist and starts to form clumps. Using your hands or a rubber spatula, turn the dough over about 6 times until it comes together. If dough is too dry,add additional milk, 1 tablespoon at a time. Gently fold in chocolate chips if using.
5. Place the dough on a lightly floured surface and pat it into a 9-inch square, about 3/4 inch thick. Cut the dough into 3 columns, then cut crosswise into 5 rows to yield 15 rectangles. Using a thin metal spatula, transfer cakes to the prepared baking sheet, about 1 to 1 1/2 inches apart. Bake untilmostly firm to the touch, about 14 to 16 minutes. Be careful not to overcook or the chocolate will burn.
