Set the Scene: Preheat that oven to 425°F (220°C) and line your baking sheet with parchment paper. It’s showtime, baby!
Mix It Up: Whisk together the flour, baking powder, baking soda, salt, and garlic powder (if you’re riding the garlic wave) in a big bowl.
Butter It Up: Toss in the cold butter cubes and cut them into the flour using a pastry cutter (or go rogue and use your fingers). Your goal? Coarse, crumbly goodness that looks like sand at a fancy beach resort.
Cheddar Dreams & Jalapeño Dreams: Stir in the shredded cheddar and diced jalapeños like you’re adding confetti to your birthday party.
Hold It Together: Pour in the cold buttermilk and give it a gentle stir. Nobody likes a tough biscuit, so don’t overmix. Just stop when the dough barely comes together.
Get Flaky: Transfer the dough onto a floured surface and pat it into a 1-inch-thick rectangle (hey, we’re not going for perfect edges here). Fold it over on itself 2–3 times like a love letter to flakiness.
Cut, Brush, Repeat: Use a biscuit cutter (or wine glass, no judgment) to cut out those biscuits. Place them on the baking sheet, brush the tops with extra buttermilk, and sprinkle some extra cheddar and jalapeño on top because we’re not here to play small.
Bake & Bask: Slide them into the oven and bake for 12–15 minutes until they’re golden, cheesy, and basically irresistible. You’ll know they’re ready because your kitchen will start to smell like pure happiness.
Eat & Enjoy: Serve warm, and prepare for applause.
