Step 1

Whisk together the flour, sugar, baking powder, and salt. Cut in the butter with a pastry blender or 2 knives until the butter is pea-sized or smaller. Add in the 1/2 cup grape juice and mix until just combined. (If you overmix it, it'll be tough)

Step 2

On a heavily floured board, press the dough into a flat disc. You can roll it thinly, but I like them a little on the thick side. Cut into bite-sized bits with a pastry cutter or ravioli wheel.

Step 3

Heat up the remaining grape juice and sugar in a large skillet with high sides until simmering. Drop in the dumplings and simmer for 10-12 minutes, stirring once or twice to make sure they don't stick together. The grape juice should thicken into a sweet gravy. Serve immediately in bowls either plain, with heavy cream drizzled on top, or a big scoop of vanilla ice cream.
