My grandma makes these every sunday morning. You will not believe it only takes 3 ingredients to make them this fluffy.

These southern 3-ingredient buttermilk biscuits are my cozy Sunday morning tradition, inspired by the way my grandma used to bake a fresh pan every week before church. They’re ridiculously simple—just self-rising flour, cold butter, and tangy buttermilk—but they bake up tall, fluffy, and golden with those tender, flaky layers everyone fights over. This is the kind of recipe you can pull together half-awake, with a cup of coffee in hand, and still feel like you’re spoiling your family (or yourself) with something special and homemade.

Serve these biscuits warm, straight from the foil-lined platter, with softened salted butter and your favorite jam or honey on the side. They’re perfect next to scrambled eggs, crispy bacon, or sausage gravy for a big southern-style breakfast. On busy mornings, I’ll split one and stuff it with a fried egg and cheese for an easy breakfast sandwich. Leftovers (if you have any!) are great reheated and served with soup, chili, or alongside a simple salad for a comforting, no-fuss meal.

Servings: 10–12 biscuits

2 1/2 cups self-rising flour, plus extra for dusting

Line a baking sheet or shallow serving pan with aluminum foil, shiny side up, and lightly spray or grease it so the biscuits don’t stick. Preheat your oven to 450°F (230°C) and let it fully heat while you mix the dough.

In a large mixing bowl, add the self-rising flour. Toss in the cold butter cubes and quickly work them into the flour using your fingertips or a pastry cutter until the mixture looks like coarse crumbs with pea-sized bits of butter scattered throughout. Try to keep the butter from warming up too much; those cold bits help create flaky layers.

Make a well in the center of the flour mixture and pour in 1 cup of the cold buttermilk. Gently stir with a fork or spatula just until the dough comes together and there are no big dry patches of flour. If it’s still too dry and crumbly, add buttermilk a tablespoon at a time until the dough is soft and slightly sticky but not soupy. Do not overmix—this is key for fluffy biscuits.

Lightly flour your countertop or a large cutting board. Turn the dough out onto the floured surface and sprinkle a little flour on top of the dough and on your hands. Gently pat the dough into a rough rectangle about 1/2-inch thick. Fold the dough in half over itself, then pat it out again. Repeat this gentle fold-and-pat process 3–4 times to build flaky layers, adding just a dusting of flour as needed to prevent sticking.

After the last fold, pat the dough out to about 3/4-inch thickness. Using a floured biscuit cutter or the rim of a floured drinking glass (about 2 to 2 1/2 inches wide), cut out biscuits by pressing straight down without twisting. Twisting can seal the edges and keep them from rising as high. Gently gather the scraps, pat them back together, and cut more biscuits until all the dough is used.

Place the biscuits close together on the foil-lined pan so their sides are almost touching; this helps them rise taller and stay soft. Slide the pan into the preheated oven and bake for 12–15 minutes, or until the tops are a deep golden brown and the layers look puffed and flaky.

While the biscuits bake, melt 1–2 tablespoons of butter in a small microwave-safe bowl or saucepan. As soon as the biscuits come out of the oven, brush the hot tops generously with the melted butter so it soaks into all the nooks and crannies and gives them that shiny, buttery finish like grandma’s.

Let the biscuits sit on the foil-lined pan for 3–5 minutes to set, then transfer the whole foil lining onto a serving platter for that casual, family-style feel. Serve warm and enjoy the fluffy, buttery layers right away.

If you don’t have self-rising flour, you can make a quick substitute: for every 1 cup of all-purpose flour, whisk in 1 1/2 teaspoons baking powder and 1/4 teaspoon fine salt (for this recipe, use 2 1/2 cups all-purpose flour, 3 3/4 teaspoons baking powder, and 5/8 teaspoon salt). To keep the spirit of the 3-ingredient recipe, I like to mix that ahead of time and store it as my “homemade self-rising” blend. For extra tang, swap a couple tablespoons of the buttermilk with sour cream or plain Greek yogurt (it will make the dough a bit thicker, so add buttermilk slowly). If your kitchen runs warm, cube the butter and pop it in the freezer for 10 minutes before mixing to keep it extra cold. For a more rustic look, skip the cutter and gently pat the dough into a round and cut it into wedges with a knife. To prep ahead on a busy week: cut the biscuits, place them on a parchment-lined sheet, and freeze until solid, then store in a freezer bag. Bake from frozen at 450°F, adding just a few extra minutes, and brush with melted butter at the end. You can also sprinkle the tops with a pinch of flaky salt after brushing with butter for a little extra flavor pop.
