Add the all-purpose flour, brown sugar, baking powder, baking soda & salt to a bowl and mix thoroughly to evenly distribute.
300 grams all-purpose flour, 56 grams brown sugar, 1 ½ teaspoon baking powder, ½ teaspoon baking soda, 1 teaspoon salt
Cube 8 tablespoons (½ cup) of the butter and rub it into the dry ingredients from the previous step until the mixture mostly resembles fine sand but still has some chunks of butter.
170 grams unsalted butter
Add the buttermilk and, using your hands, form the mixture into a dough just until combined. Avoid using a full kneading motion and instead, push the dry ingredients into the wet portion of the dough repeating this until there are no more dry spots.
180 milliliters cultured buttermilk
On a floured surface roll the dough out until half-inch thick.
Spread the remaining 4 tablespoons (¼ cup) of butter evenly across the surface of the rolled out dough. If slicing the butter be sure to make cuts as thin as possible.
170 grams unsalted butter
Roll the dough up lengthwise then tuck the ends inward to form a ball.
Roll the dough out again until a half to three-quarters inch thick and cut into your desired shapes. Whatever your tool of choice, use one downward motion to cut; do not drag or twist.
Be sure to trim just enough of the folded over edges to expose the layers. This maximizes rising!
Arrange the biscuits on a baking sheet leaving at least an inch of space around each. Alternatively, you can arrange in a pan close together for pull-apart biscuits.
Bake for 12-15 minutes until golden brown. If the biscuits were arranged closer together the baking time will be about 5 minutes longer.
Enjoy warm with your favorite toppings and/or alongside your favorite breakfast mains!
