In a medium bowl add the flour, baking powder, dried oregano, sugar, and salt. Mix until combined.
Add in the cold butter and rub your fingers through the flour and butter to make it almost like a sand consistency.
Add the diced chili and grated cheese in the bowl and mix until well combined.
Make a hole in the middle and pour in the milk in the bowl.
Carefully form a soft dough. Let it rests in the bowl covered with plastic wrap in the fridge for 20 minutes.
On a lightly floured surface roll out the dough into ½ inch thickness and with the round cookie cutter that is floured cut the biscuits and arrange them in a cookie sheet lined with parchment paper.
Bake in a preheated oven at 400 F or 190 C degrees for about 15-20 minutes.
Remove them from the oven and add a little sprinkle on top of each biscuit grated cheese and chopped chili.
Place them bake in the oven for another 5-10 minutes until the cheese is fully melted and they are all golden brown in color.
