Start mixing the flour, sugar, baking powder and salt in a large mixing bowl.
Then mix in the milk
Add the egg and vanilla.
Mix well, then add the vanilla.
Fold in the strawberries.
Meanwhile spray your baking loaf pan with non-sticking cooking spray (I am a big fan of the one with the flour, I find that my baked goods don't stick as much)
Pour the batter in.
Set the temperature for 310 F, and the time for 30 minutes. After 30 minutes check and check for doneness. If it is not done, add another 5 minutes. Until it's fully cooked, and a toothpick comes out clean.
Once fully cooked, remove the loaf pan, from the air fryer basket, let cool slightly.
Once cooled, slice and serve.
