In a measuring cup or small bowl, add the lemon juice to the milk and set aside to slightly curdle to make buttermilk.
1 cup milk, 1 tablespoon lemon juice
In a large mixing bowl, whisk together the flour, brown sugar, baking powder, and salt.
1 cup all-purpose flour, 2 tablespoons brown sugar, 2 teaspoons baking powder, 1/2 teaspoon salt
Add the egg, vanilla extract, and buttermilk mixture. Whisk until smooth, careful not to overbeat.
1 large egg, 1 teaspoon vanilla extract
Fold in diced mango and transfer batter to a measuring cup or other container with spout for easy pouring.
1 cup diced mango
Add butter to your griddle or pan and allow it to heat up on medium-high until the butter is melted. For the thickest, most perfectly round pancakes, use pancake molds. Pour batter into your molds or freeform circles onto the pan and cook over medium heat. 3 tablespoons unsalted butter
When it's ready to flip, the batter on the uncooked side will start to form little air bubbles. Use a spatula to flip the pancakes, and allow them to cook on the other side for 2-3 minutes.
Repeat steps 5 and 6 until the pancake batter is used up, adding butter before each batch to keep your griddle greased. Option to top with extra diced mango. Serve warm with maple syrup. Try them with these Vegan Breakfast Sausage Patties!
