Sourdough Biscuit Recipe

Sourdough biscuits that are both fluffy and flaky. A little discard sourdough starter gives these biscuits a wonderful flavor.
Prep Time: 20 minutes
Bake Time: 12 minutes
Total Time: 32 minutes
12 biscuits

Ingredients 

  • 10 oz all purpose flour (2 cups, see note)
  • 8 oz cake flour (2 cups)
  • 4 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1 tablespoon granulated sugar
  • 1 teaspoon table salt
  • 8 oz unsalted butter (cold and cut into 16 pieces)
  • 8 oz sourdough discard (1 cup, room temperature)
  • 8 oz buttermilk (1 cup, room temperature)

Instructions

  • Preheat the oven to 400 °F. Line a half sheet pan with parchment paper.
  • Combine 10 oz all purpose flour, 8 oz cake flour, 4 teaspoons baking powder, 1 teaspoon baking soda, 1 tablespoon granulated sugar, and 1 teaspoon table salt in a mixing bowl. Whisk the dry ingredients to combine.
  • Mix 8 oz unsalted butter into the flour with your fingers until it's broken down into bits slightly larger than a pea.
  • Combine 8 oz sourdough discard and 8 oz buttermilk in a small bowl. Add the buttermilk mixture to the flour all at once. Mix until about 2/3 of the dry ingredients are absorbed.
  • Turn the dough onto a lightly floured surface and gently knead together just to incorporate the remaining dry flour (this should only take about 6-8 kneads).
  • Gently pat dough to a 1/2" thick rectangle, brush off excess flour and fold the dough in 1/2. Pat gently to stick the dough together and and fold again. Pat to 3/4 " thick disc and cut with a 2.5"-3" biscuit cutter. Gather the scraps together, pat to 3/4" thick and continue cutting until all the dough is used up.
  • Set the biscuits onto the prepared baking sheet and brush the tops with buttermilk. Bake the biscuits until well rise and golden brown, about 10-12 minutes.
  • If the bottoms of the biscuits are browning too fast set another sheet pan under the biscuits after 5 minutes of baking.

Notes

If measuring the flour by volume use the “dip & sweep” method. That is, dip the measuring cup into the flour bin, overfill it, then sweep away the excess.
