Heat one tablespoon of olive oil in a skillet over a medium heat. Thinly slice the onion and add to the pan along with the balsamic vinegar and maple flavored syrup. Stir well to combine. Cook for 1-2 minutes until just tender then reduce the heat to low. Continue to cook for a further 5-6 minutes until the onions are sweet, soft and slightly caramelized.
Step 2
Whilst the onions are cooking, heat the remaining olive oil in a separate skillet over a medium heat. Add the bacon and cook through until golden brown. Keep warm and set to one side.
Step 3
Preheat a broiler to medium.
Step 4
Divide the caramelized onions between the four pancakes.
Step 5
Tear the bacon strips in half and arrange two halves on each pancake.
Step 6
Roughly dice the Brie and arrange on top of the bacon.
Step 7
Transfer the pancakes to a grill tray and broil for 3-4 minutes until completely hot through and the Brie has melted.
Step 8
Finely chop the rosemary and sprinkle over the pancakes along with a generous pinch of black pepper to serve.
