Sift the flour, baking powder and salt into a bowl. Make a well in the centre and gradually beat in the egg and milk. Continue to beat until the batter is smooth. Stir in the melted butter.
Heat a heavy-based frying pan until hot, spray lightly with spray oil and spoon on about 100 ml (3½ fl oz) of the pancake batter. Cook over a medium heat for 1–2 minutes until bubbles start appearing on the surface. Carefully flip the pancake over and cook for a further 1–2 minutes until browned on the underside. Remove from the pan and keep warm in a preheated oven, 150°C (300°F), Gas Mark 2, while you cook the remainder of the batter – it should make 8 pancakes in total.
Meanwhile, cook the bacon under a preheated high grill for 2 minutes on each side until golden.
