Ingredients
 

Biscuit Batter

  • 2 cups all-purpose flour
  • 2 tbsp granulated sugar
  • 1 tbsp baking powder
  • 3/4 tsp kosher salt
  • 1 tsp ground cinnamon
  • 1 2/3 cups cold buttermilk shake well
  • 1 tsp vanilla extract

Cinnamon Sugar

  • 1/4 cup granulated sugar
  • 1/4 cup light brown sugar, packed
  • 1 1/2 tsp ground cinnamon
  • 1/8 tsp kosher salt

Pan Butter

  • 1/2 cup unsalted butter for the baking pan

Optional Glaze

  • 1/2 cup powdered sugar
  • 2 tsp milk add more to thin as needed
  • 1/4 tsp vanilla extract

Instructions

Preparation Steps

  • Preheat oven to 450°F. Put butter in an 8x8 metal pan.
  • Slide pan into oven until butter melts and sizzles.
  • Whisk flour, sugar, baking powder, salt, and cinnamon.
  • Stir in buttermilk and vanilla until just combined.
  • Pour batter into hot buttered pan. Do not stir.
  • Mix granulated sugar, brown sugar, cinnamon, and pinch salt.
  • Sprinkle cinnamon mix evenly over batter.
  • Drag a knife through to marble the top.
  • Bake until puffed and deep golden, 22–26 minutes.
  • Cool 10 minutes. Slice and serve warm.
  • Whisk glaze ingredients. Drizzle over warm biscuits, if desired.

Notes

No buttermilk? Stir 1 tbsp lemon juice into 1 2/3 cups milk and rest 5 minutes. Try cardamom with the cinnamon, or swap in nutmeg. Prefer salted butter? Reduce added salt slightly. A 9x9 pan works; start checking 3–4 minutes earlier.
