Mix oatmeal, whole wheat flour, baking powder, and salt together in a bowl.
Cut in the cold butter and mix with your hands until the mixture becomes crumbly like streusel.
Add milk and honey, and bring the dough together into one mass.
Shape the dough, flatten it, and divide into 6 pieces.
Bake in a preheated oven at 180°C for 20 minutes.
