Gather all the ingredients. Please Watch the Video attached for better understanding. Always read the NOTES for tips & more choices.

Prepare Apple Filling

• Wash & Peel the apples. Chop the into small cubes or pieces. Set aside.
• Now take a Mixing Bowl. Add lemon juice, Cinnamon Powder & Brown Sugar to the bowl. Mix these well. Now add chopped apples. Mix and coat them well with the cinnamon sugar. 
• Divide the apples filling equally into 2 parts. Take the Ramekins and fill 2/3rd of them with the apple filling. If you are using one baking dish then no need to divide. Just fill it with the apple filing.
• Cover the ramekins with the Aluminum Foil tightly. Place them in the air fryer basket. Set the temperature to 350*F/180*C & timer to 15 minutes. Air Fry.
• Once timer is done, take these out carefully. These will be hot so be careful. Use these silicone kitchen gloves to avoid any burnt fingers later.

Prepare Streusel Topping or Crisp Topping

• Meanwhile the apples are getting air fried, we can work on that streusel topping.
• Take the same mixing bowl. Add All purpose flour, Quick cooking Oats ,Salt & brown sugar to it. Mix.
• Now add small cubes of cold butter to the flour mix. Start mixing with your fingers. You can use a fork or pastry cutter too. 
• Bring the ingredients together in a dough. You are not going to knead the dough, but just collect it together. Refrigerate this streusel dough till ready to use.

Air Frying Apple Crisp

• Once you take the ramekins out, take that streusel dough out of the refrigerator too.
• Now divide that streusel dough into 2 equal parts and spread on top of the baked apples. It doesn't matter if it is slightly uneven. Rustic appearance looks amazing.
• Now place these uncovered ramekins back into the air fryer basket. Air fry further for 5 minutes to cook the top. 
• Once done, take these out. Top with your choice of topping and serve while still hot. I loved topping mine with coffee ice cream. Kids topped theirs with berry ice cream & cookie dough ice cream.
