Begin by preheating your air fryer to 180C/350F. This ensures that your biscuits cook evenly and develop a beautiful golden color. It’s essential to have the right temperature before placing your dough in.
Sift the self-rising flour into a mixing bowl. This step helps aerate the flour, ensuring your biscuits rise light and fluffy. It may seem small, but it makes a significant difference in texture.
Next, take your frozen butter and using a box grater, grate it directly into the bowl with the flour. This method allows the butter to blend into the flour perfectly without becoming too warm.
Using your hands, gently mix the butter with the flour, ensuring the mixture resembles coarse crumbs. Be careful not to overwork the dough; you want to keep that flaky texture.
Make a well in the center of the mixture and pour in the buttermilk. Mix everything together until just combined. The dough should be slightly sticky but manageable.
Lightly flour a clean kitchen surface. Transfer the dough onto it and gently knead it several times. Be cautious not to over-knead; you want the biscuits to remain tender.
Roll the dough flat, aiming for about one inch in thickness. This thickness is ideal for biscuits as it allows them to rise well while still cooking through.
Using a biscuit cutter or a large cookie cutter, cut out the biscuits from the rolled-out dough. The key is to press straight down without twisting, which helps them rise evenly.
Generously grease your air fryer basket to prevent sticking. Place four biscuits in the basket, ensuring they are lightly touching. This helps them form a lovely crust as they cook.
Air fry the biscuits for 9 to 10 minutes, or until they are golden brown. Keep an eye on them; every air fryer is a little different. You’re looking for that perfect golden hue!
Once cooked, remove the biscuits from the air fryer and repeat the process with the remaining dough. Enjoy these warm, flaky biscuits fresh out of the air fryer!
