Preheat the oven to 375 degrees F. Grease two 12-cup muffin tins with butter.
Sift together the flour, baking powder and salt in a medium bowl. Using a pastry cutter, cut in the butter until all combined. Whisk together the milk, oil and eggs in a separate bowl. Combine the flour mixture, milk mixture, Cheddar and green chiles in a large bowl. Stir gently until combined.
Spoon the batter into the prepared tins. Bake until golden, 20 to 22 minutes. Remove from the tins and serve warm.
