- STEP 1 - Put the flour into a bowl and mix in the butter, which should be at room temperature, then add the sugar and vanilla extract and mix with your hands until you have a dough. 
- STEP 2 - Prepare your baking tins with greaseproof paper 
- STEP 3 - Bake in the HYSapientia air fryer oven at 160 for 15 mins 
- STEP 4 - For the shortbread fingers, I rolled them out and shaped them neatly. 
- STEP 5 - Roll out the dough to 1/2 inch thick and for the petticoat tails, put some dough in the tin and press until flat. 
- STEP 6 - I used a fork to poke holes in both, which makes the shortbread crispier and helps it absorb moisture, leaving a buttery taste throughout. Sprinkle with granulated sugar.
