Preheat oven to 400 degrees.

In a mixing bowl, combine the flour, baking powder, and salt. Cut the butter into the flour until the largest pieces are the size of peas. Add the garlic, shredded cheese, and green chiles. Stir to combine, then add the milk and stir to form a dough. Drop the mixture by the scoop or spoonful onto parchment-lined baking sheets. Bake until nicely golden brown, about 11-14 minutes depending on their size.
