In a large mixing bowl, whisk together the low-fat buttermilk, eggs, melted butter, and vanilla extract until combined.
Sift the whole wheat flour, baking powder, baking soda, and sea salt into the wet ingredients. Using a spatula, gently fold the dry ingredients into the wet mixture until just combined, do not to overmix. Let the batter rest for 20 minutes for fluffier pancakes.
Coat silicone molds or a safe parchment liner with non-stick cooking spray. Fill each mold with a small scoop of batter, ensuring they are not overfilled.
Place the filled molds in the basket. Set the Air Fryer to 350°F and cook for 5 minutes, or until the tops start to turn golden. Using tongs, flip the pancakes and cook for an additional 4 minutes, or until fully cooked.
Remove the pancakes from the Air Fryer and repeat the process with the remaining batter.
Serve with a pat of butter, honey or maple syrup. You can also add seasonal berries or sliced fruit.
