Preheat oven to 400°. Grease a baking sheet.
In a large bowl, whisk all dry ingredients together.
In a small bowl, mix all wet ingredients together. Pour into large bowl, stirring until thoroughly combined. Use your hands to knead dough. If batter is too dry to knead into a ball, add 1-2 more tablespoons of milk. Fold in blueberries.
Sprinkle extra flour on a clean surface. Form batter into ball and flatten only little, keeping the edges round. Use a sharp knife to slice dough into 4 triangles. Place pieces on baking sheet.
Bake for 15 minutes, or until edges are golden brown. Remove from oven and let cool for at least 15 minutes before enjoying.
Serve and enjoy!
