1Cook the bacon to your desired texture, pat dry, and let cool completely. Halve each slice.
2Preheat oven to 180C/350F. Place baking paper on a baking tray and place a 10cm/4" ramekin in the center. Unpack the croissant dough and separate each triangle. Arrange them around the ramekin, overlapping as needed.
3Remove the ramekin and spread cranberry sauce in the center. Top with bacon, brie, and chilli flakes (optional). Fold the dough corners to cover the filling.
4Brush with egg wash and sprinkle with poppy seeds (optional). Bake for 17-20 minutes, until golden and crisp.
