Air Fryer Buttermilk Biscuits are wonderfully crisp on the outside and light and tender on the inside. They air fry in just 12 minutes.
Whisk together flour, baking powder, sugar, salt and baking soda in a large bowl.
Add the butter and work it in with your fingers until there are no pieces larger than a pea.
Pour the buttermilk evenly over the mixture and use a rubber spatula to mix it in.
Mix just until a dough comes together. If there is any loose flour that won't mix in, add a drizzle more buttermilk.
Turn the dough out onto a floured surface. Pat it into a 1/2-inch thick circle.
Use a 2 1/2-inch biscuit cutter to cut as many biscuits as you can. You can reroll the scraps to cut one more.
Note: Use an up and down motion with the biscuit cutter. Do not twist.
Spray the air fryer basket with cooking spray and air fry half of the biscuits at 325 degrees for 12 to 16 minutes.
Refrigerate the remaining ones.
Once the first batch is done, remove the ones from the refrigerator and repeat.
If desired, brush the tops of the cooked biscuits with melted butter.
You can use unsalted butter. Just add a pinch more salt.
Your butter and buttermilk should be very cold. It also helps to stick the bowl you will be using in the refrigerator beforehand so it will be cold too.
