Blueberry Biscuits and Blueberry Sauce

Preheat oven to 425 degrees. Line a baking sheet with parchment paper. Lightly grease the parchment paper.
In a large bowl, whisk together flour, baking powder, sugar and salt. Add blueberries and toss together. Stir in enough milk to make a dough that’s not too sticky. Turn dough out onto prepared baking sheet and form into an 8-inch square. Score the dough into 16 squares, leaving them still attached. Bake until golden brown, then remove from oven and pull biscuits apart. Top with Blueberry Sauce.
Blueberry Sauce
2 cups blueberries, divided
1/3 cup granulated sugar
2 tablespoons water
1 teaspoon vanilla
In a medium saucepan combine 1 cup blueberries, sugar and water. Bring to a simmer and cook until blueberries pop and sauce has thickened. Remove from heat, then stir in the vanilla and remaining blueberries. Serve warm or at room temperature.
