In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and fine sea salt until well combined.
In a separate bowl, mix the buttermilk, egg, melted unsalted butter, and pure vanilla extract. Whisk the mixture until it is completely smooth.
Pour the wet mixture into the bowl with the dry ingredients. Using a spatula, gently fold the two mixtures together until just combined; remember, a lumpy batter is ideal and helps keep the pancakes fluffy.
Carefully fold in the diced mango, ensuring that the pieces are evenly distributed throughout the batter without the urge to overmix.
Preheat a non-stick skillet or griddle over medium heat, then lightly grease it with a touch of butter or vegetable oil to prevent sticking.
For each pancake, pour approximately 1/4 cup of the pancake batter onto the skillet. Cook until bubbles form on the surface and the edges of the pancake appear set, approximately 2-3 minutes.
Gently flip the pancakes and continue to cook for an additional 1-2 minutes, or until they are beautifully golden brown and fluffy.
Transfer the cooked pancakes to a warm plate and repeat the process with the remaining batter, applying more butter or oil to the skillet as necessary.
Serve the warm pancakes immediately, garnished with extra diced mango, a generous drizzle of maple syrup, and a light dusting of powdered sugar for that extra touch of sweetness.
Notes
Stack the pancakes and garnish with fresh mint and extra mango for a beautiful presentation.
