In a medium bowl, whisk all-purpose flour, whole wheat flour, baking powder, baking soda, and salt.
In a large bowl, mash bananas witha fork. Add egg, brown sugar, oil, sour cream, and vanilla and whisk to combine.
Add dry ingredients to wet ingredients and stir until just combined. Fold in blueberries.
Scoop batter with a 2.5-oz. scoop or 1/3-cup measuring cup into 14 silicone muffin liners. Top with 1 banana chip.
Working in batches, in an air-fryer basket, arrange filled muffin liners, spacing about 1/2" apart. Cook at 350° for 7 minutes. Tent tops with foil to prevent overbrowning, then continue to cook until puffed and a tester inserted into center comes out clean, 5 to 7 minutes more.
Transfer muffins to a wire rack and let cool.
