Overnight Sourdough Biscuits
Recovered the overnight sourdough biscuit concept and completed the missing cup-based formula and method while retaining the source's cold-ferment, rough-dough, butter, folding, baking-soda, apple-starter, and cheddar-serving guidance.

This usable formula completes the missing recipe from the family source; it is not recorded as family-tested. The overnight refrigerator rest develops tang and keeps the butter cold. Expect the dough to look rough and nearly too dry before resting; it should become more cohesive overnight. In the morning, add the chemical leaveners, fold the dough to create flaky layers, cut cleanly, and bake until tall and golden.

Method
Cut in the butter
Whisk together the flour, sugar, and salt. Cut or toss the very cold butter into the flour until the mixture contains pea-size pieces and some thin flakes.
Mix the overnight dough
Stir together the sourdough starter and 1/2 cup cold buttermilk. Add to the flour mixture and fold gently until a rough, shaggy dough forms. Add extra buttermilk only if dry flour will not gather when pressed.
Refrigerate overnight
Cover the dough and refrigerate for 8–12 hours. It may look almost too rough and dry before resting; this is expected.
Heat the oven
The next morning, heat the oven to 425°F. Line a baking sheet with parchment paper.
Add the leaveners
Whisk the baking powder and baking soda together. Pat the cold dough into a rectangle, sprinkle the leaveners evenly over it, and fold and press gently several times to distribute them without warming the butter.
Build flaky layers
Pat the dough about 1 inch thick. Fold it in thirds like a letter, turn it 90 degrees, and repeat twice more. If the butter begins to soften, chill the dough for 10–15 minutes.
Cut the biscuits
Pat the dough 3/4–1 inch thick. Cut straight down with a floured biscuit cutter without twisting. Place the biscuits close together on the prepared pan for softer sides or farther apart for crisper sides.
Bake
Bake for 15–18 minutes, until risen and deeply golden. Brush with melted butter if desired and serve warm.
Safety & handling
- Keep the dough refrigerated during the overnight rest; this is a cold fermentation, not a room-temperature dairy rest.
- Bake promptly after shaping and refrigerate leftover biscuits after cooling if they will not be eaten within a day or two.
Insider tips
- Keep the butter cold throughout; the refrigerator rest helps preserve solid butter pockets that create flaky layers in the oven.
- The dough should look rough and nearly too dry when it enters the refrigerator; the flour hydrates and the dough becomes more cohesive overnight.
- Folding the dough stacks layers and improves flakiness.
- Baking soda reacts with the acidity developed during the overnight rest and supports the morning rise.
- Serve split and warm with melted cheddar, as suggested in the source.
Family notes
- Heather requested a best-ever overnight version measured in cups.
- The source refers to Heather's apple sourdough starter.
- A warm biscuit split open with cheddar was the suggested serving idea.
