1-First Step: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper. This high heat ensures quick rise and crisp bottoms. Measure all ingredients mise en place style to keep things smooth.

2-Second Step: In a large bowl, whisk together 2 cups all-purpose flour, 1 tablespoon baking powder, 1/4 teaspoon baking soda, and 1 teaspoon salt. Sift if lumpy for even distribution. This dry mix sets the foundation for uniform lift.

3-Third Step: Add 6 tablespoons cold cubed unsalted butter to the flour mixture. Use a pastry cutter or fork to cut it in until pea-sized crumbs form. Work quickly to keep butter cold; warm butter leads to tough biscuits. If no cutter, grate frozen butter.

4-Fourth Step: Pour in 1 cup cold buttermilk. Stir with a wooden spoon or spatula just until dough comes together. It will be shaggy and sticky; avoid overmixing to preserve tenderness. Excess stirring develops gluten, making biscuits dense.

5-Fifth Step: Turn dough onto a lightly floured surface. Gently pat into a 1-inch thick rectangle. Fold in half like a letter, pat down again, and repeat 2-3 times. This lamination creates flaky layers without kneading. Pat to 3/4-inch thick for 12 biscuits.

6-Sixth Step: Use a 2.5-inch biscuit cutter dipped in flour to cut rounds. Press straight down without twisting to ensure rise. Place biscuits 1 inch apart on the sheet. Gently reform scraps once for extra biscuits.

7-Final Step: Brush tops with 2 tablespoons melted butter if desired. Bake 12-15 minutes until golden brown. Rotate sheet halfway for even browning. Cool 5 minutes on rack. Serve warm with butter, honey, or gravy. Yields 10-12 fluffy biscuits.
