Make the 'buttermilk' by whisking together the milk and lemon juice in a small bowl; set aside for 5 minutes.
Make the pancake batter by whisking together the dry ingredients, adding the eggs and melted butter to the milk mixture, then combining with the flour mixture until no lumps remain.
Make the pancakes in batches by spooning the batter into a lightly greased skillet, cooking until bubbles form and edges look dry, then flipping and cooking the other side.
Serve the pancakes in a stack, drenched with maple syrup.
