You will need gluten-free flour, baking powder, salt, butter, milk (or dairy-free alternative) and sweetener if desired.
In a bowl, combine the gluten-free flour, baking powder and salt, ensuring they are well mixed for even texture, gradually pour in milk and mix until a dough forms.
Cut in cold butter until the mixture resembles coarse crumbs. The dough should be binding, neither sticky nor dry.
Bake in a preheated oven at 170°C for about 12-15 minutes, or until golden brown.
