Preheat the oven to 180°C (356°F).
In a large bowl, mix whole wheat flour, baking powder, and salt.
Cut chilled unsalted butter into small pieces and rub it into the flour mixture with your fingertips until evenly combined.
Add low-fat milk, honey, and Greek yogurt, then mix gently with a spatula.
Once the dough comes together, divide it into suitable portions.
Shape the dough into rounds and place them on a baking sheet.
Bake in the oven for 18–20 minutes.
