Add the flour, baking powder and sugar to a large bowl and stir to combine. Make a well in the centre and add the milk, eggs, lemon juice, lemon zest, poppy seeds, and melted butter. Whisk until barely combined – it should still be lumpy.
Place a frying pan over a low to medium heat. Brush with melted butter or oil. Scoop about a 1/2 cup of batter onto the pan.
Fry for about 1-2 minutes – flipping when the air bubbles on the surface of the batter begin to pop. Fry for another minute, then remove and repeat for all remaining batter.
Serve the pancakes with the homemade lemon curd, fresh whipped cream, powdered sugar and any other desired toppings!
