Fluffy Baking Soda Biscuits
These biscuits are the ones you make when you want warm, tender bread on the table in under half an hour. There’s no yeast, no waiting, just a quick dough that puffs up light and golden.
They rely on baking soda and cold buttermilk for their lift, which means a tender crumb with crisp edges and a buttery, slightly tangy flavor. A bowl of soup or a pat of jam is all they need to feel like a complete meal.
Why These Biscuits Work
The lift comes from baking soda reacting with the acid in buttermilk, creating tiny bubbles that expand in the hot oven. That reaction works fast, so the dough goes from mixing bowl to baking sheet in minutes.
Cold butter cut into the flour forms flat, pea-sized pieces. Those butter bits melt during baking, leaving small steam pockets that turn into flaky layers. The dough stays cold, and the biscuits rise tall because the butter doesn’t leak out too soon.
You end up with biscuits that are soft inside, crisp on the outside, and just salty enough to keep you reaching for one more.
Ingredients
- 2 cups all-purpose flour, plus more for dusting: spoon and level for an accurate measure.
- 1 tsp baking soda: check the expiration date so it’s still active.
- 1/2 tsp fine salt: sea salt or table salt both work.
- 1 tbsp granulated sugar: optional, but it helps the tops brown and rounds out the tang.
- 6 tbsp cold unsalted butter, cut into small cubes: keep it in the fridge until you need it.
- 1 cup cold buttermilk: the acid activates the soda; don’t swap with plain milk.
Variations and Substitutions
- Whole wheat flour: replace up to half of the all-purpose flour with whole wheat for a nuttier biscuit.
- Sugar-free: leave out the sugar for a more savory biscuit.
- Herb biscuits: stir 1 tbsp chopped fresh rosemary or thyme into the dry mix before adding butter.
- Buttermilk substitute: stir 1 tbsp lemon juice or white vinegar into 1 cup whole milk and let it sit 5 minutes.
- Dairy-free: use a cold plant-based butter stick and the buttermilk substitute with unsweetened oat or soy milk.

How to Make Baking Soda Biscuits
Step 1: Mix the Dry Ingredients
Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper. In a large bowl, whisk together the 2 cups flour, 1 tsp baking soda, 1/2 tsp salt, and 1 tbsp sugar if using.
Make sure the baking soda is evenly distributed so you don’t get any bitter spots.
Step 2: Cut in the Butter
Toss the 6 tbsp cold butter cubes into the flour mixture. Using a pastry cutter or your fingertips, quickly work the butter into the flour until the biggest pieces are about the size of a pea.
The mixture should look like coarse meal with some visible flat butter pieces. Those chunks of butter are what create flaky layers, so don’t overwork them into sand.
Step 3: Stir in the Buttermilk
Pour the 1 cup cold buttermilk into the bowl all at once. Stir gently with a fork just until a shaggy dough comes together.
The dough will look rough and a little dry in patches, which is exactly right. Stop as soon as the flour disappears. Overmixing at this stage develops gluten and makes the biscuits tough.
Step 4: Pat Out the Dough
Turn the dough out onto a lightly floured counter. With floured hands, pat it into a rectangle about 3/4 inch thick. Fold the dough in half onto itself, then pat it out again to the same thickness. This folding step creates extra flaky layers.
Dip a 2 1/2-inch biscuit cutter in flour and press straight down without twisting. Twisting seals the edges and stops the biscuits from rising tall. Gather any scraps, pat them together once more, and cut the remaining biscuits.
Step 5: Bake Until Golden
Place the biscuits on the prepared baking sheet. Arrange them close together with sides touching for softer edges, or space them an inch apart for crispier outsides. Bake for 12 to 15 minutes, until the tops are deep golden brown and the biscuits have risen high.
Slide the pan out and brush the hot biscuits with a little melted butter if you like. Serve them right away while the crust is crisp and the inside steams.
Tips for the Best Biscuits
- Keep everything cold. Chilled butter, cold buttermilk, and a light touch with your hands prevent the fat from melting before baking. If the kitchen is warm, pop the bowl in the fridge for 10 minutes after cutting in the butter.
- Don’t overwork the dough. The less you handle it, the more tender the biscuits. Pat and fold gently, and stop as soon as the dough holds together.
- Use a sharp cutter. A dull glass or a can compresses the edges. A metal biscuit cutter with a thin rim gives the cleanest cut and the best rise.
- Freeze unbaked biscuits for later. Place the cut biscuits on a tray and freeze until solid, then transfer to a bag. Bake from frozen, adding 2 to 3 minutes to the time.
Bake times by dough thickness:
| Thickness | Bake Time |
|---|---|
| 1/2 inch | 10 to 12 mins |
| 3/4 inch | 12 to 15 mins |
| 1 inch | 15 to 18 mins |
Storing Leftover Biscuits
- Refrigerator: keep baked biscuits in an airtight container for up to 3 days. They’ll lose some crispness but stay tender.
- Reheating: warm them in a 350°F (175°C) oven or toaster oven for 4 to 5 minutes to bring back the crust. The microwave works in a pinch but makes them soft.
What Goes Well with Baking Soda Biscuits
Split them and spoon over a rich sausage gravy for a hearty breakfast. They are also a natural alongside fried chicken because the crisp, flaky layers balance the juicy meat. A bowl of beef stew is another good match, the biscuits soak up the gravy without falling apart.
Frequently Asked Questions
Can I use baking powder instead of baking soda?
No, the chemistry is different. Baking soda needs an acid like buttermilk to react, while baking powder already contains acid. If you swap, you’ll get a flat, dense biscuit.
My biscuits didn’t rise, what went wrong?
The most likely cause is expired baking soda. Also check that your butter and buttermilk were cold, and that you didn’t twist the cutter when cutting.
Can I make these dairy-free?
Yes. Use a cold plant-based butter stick and replace the buttermilk with 1 cup unsweetened oat or soy milk mixed with 1 tbsp lemon juice. Let it sit 5 minutes before using.
Do I need cake flour for lighter biscuits?
No, all-purpose flour works well. If you want a more tender crumb, you can replace 1/4 cup of the all-purpose flour with cake flour.
