This is a great homemade buttermilk biscuit recipe I like to use. To make tall, fluffy, and flaky homemade biscuits from scratch, use cold butter, handle the dough gently, and fold the dough to create layers. Ingredients • 2 cups all-purpose flour • 1 tablespoon baking powder (fresh and aluminum-free) • ½ teaspoon baking soda • 1 tablespoon granulated sugar • 1 teaspoon fine sea salt • 6 tablespoons (85 g) cold unsalted butter, cubed • ¾ cup plus 2 tablespoons cold buttermilk or whole milk • 2 tablespoons melted butter (for brushing after baking) Step-by-Step Instructions 1. Preheat and Prep: Preheat your oven to 425°F (218°C). Line a baking sheet with parchment paper or set aside a cast-iron skillet. 2. Mix Dry Ingredients: In a large bowl (or food processor), whisk together the flour, baking powder, baking soda, sugar, and salt. 3. Cut in the Butter: Add the very cold cubed butter. Use a pastry cutter, a box grater, or your fingertips to work the butter into the flour until the mixture resembles coarse crumbs with a few pea-sized pieces remaining. Keeping the butter cold is the secret to fluffy pockets of steam. 4. Add the Liquid: Pour in the cold buttermilk or milk. Stir gently with a fork or spatula just until a shaggy, cohesive dough forms. Do not overmix. 5. Fold for Layers: Turn the dough out onto a lightly floured surface. Gently pat it into a rough rectangle (about ¾-inch thick), then fold it into thirds like a letter. Rotate the dough 90 degrees and repeat this patting and folding process 2 to 3 times to build flaky layers. 6. Cut the Biscuits: Pat the dough down to about ½- to ¾-inch thick. Press a round biscuit cutter straight down into the dough without twisting. (Twisting seals the edges and stops the biscuits from rising.) 7. Bake Close Together: Place the biscuits touching or nearly touching on your baking sheet or skillet (this helps them support each other to rise taller). 8. Bake: Bake for 10 to 15 minutes until the tops are deeply golden brown. Immediately brush the tops with melted butter when they come out of the oven.
