In a medium bowl, whisk together flour, baking powder, remaining 1 teaspoon lemon zest, and salt. Add cubed cold butter and cut in using fingers or a fork until the mixture forms pea-sized crumbs. Gradually stir in heavy cream to create a wet, shaggy dough.

Transfer the blueberry mixture into a medium baking dish. Using a spoon or ice-cream scoop, drop spoonfuls of biscuit dough over the fruit, leaving small gaps for steam and juices to escape.
