In a large mixing bowl, cream together the butter and sugar.
Slowly add the eggs, sour cream, lemon juice, lemon zest, and vanilla extract.
Mix in the flour, baking powder, baking soda, and salt.
Mix well.
Spray your baking pans with olive oil. Pour the batter into the prepared pan, about 2/3 way full.
Set the pan into the air fryer, and set the temperature to 320 degrees F for 20 minutes. (air fryer setting)
When the time is up, place a toothpick in the pound cake, and check to see that the toothpick comes out clean. If not, add another 5 minutes.
Let cool slightly before adding the icing.
To make the icing simply, whisk together in a small bowl the sugar, lemon juice, and milk. Spread over the cooled pound cake.
Plate, serve, and enjoy!
