Instructions
Preheat the oven to 425°F and line a baking sheet with parchment paper. Blend the cottage cheese and vanilla until completely smooth and refrigerate it.
Rub the lemon zest into the sugar with your fingertips until fragrant and damp. Whisk it with 2 1/2 cups flour, baking powder, baking soda and salt, then grate in the frozen butter and toss to coat.
Toss the frozen blueberries with 1 tablespoon of flour, keeping them frozen so they do not bleed into the dough. Add them to the bowl along with the blended cottage cheese.
Stir gently with a fork until a shaggy dough forms, adding milk 1 tablespoon at a time only if dry flour remains. Turn it onto a floured surface and pat it into an 8-inch square about 1 inch thick.
Cut the dough into 9 squares with a bench scraper and place them 2 inches apart on the baking sheet. Bake for 17-20 minutes, until golden and the blueberries are bursting.
Whisk the powdered sugar, lemon juice and zest into a smooth glaze. Drizzle it over the warm biscuits and let it set for 10 minutes before serving.
