Preheat your oven to 425°F (220°C). This will ensure that your biscuits rise beautifully and develop a golden crust.
In a large mixing bowl, whisk together the all-purpose flour, sugar, baking powder, baking soda, and salt until well combined.
Add the chilled, cubed butter to the dry mixture. Using a pastry cutter or fork, cut the butter into the flour until the mixture resembles coarse crumbs.
Gently fold in the grated cheddar cheese, finely chopped garlic, and fresh cilantro.
Pour in the cold buttermilk and stir until just combined. The dough will be slightly sticky.
Turn the dough out onto a floured surface and gently pat it into a rectangle about 1-inch thick. Use a biscuit cutter or a glass to cut out biscuits.
Bake the biscuits in the preheated oven for 12-15 minutes, or until they are golden brown on top.
Once baked, remove the biscuits from the oven and allow them to cool for a few minutes before serving. They are best enjoyed warm!
