In a large bowl, or the bowl of a stand mixer, add the flour and yeast and combine. Add in the salt and combine again.
Make a well, pour in 3 tbsp Olive Oil and about 350ml warm water (not hot). Combine to form a dough. It should come together but be pretty sticky. If not, add more water.
Knead using the dough hook attachment or your hands on a lightly floured work surface for about 8 minutes (it should be soft, smooth but still sticky). Oil the bowl you used for the dough, place the dough back in it, cover with a tea towel and let rest for an hour – until doubled in size.
Punch the dough down and we're going to "fold" it. Pick up one side of the dough, stretch it up and fold over onto the rest of the dough. Rotate the bowl 90 degrees and repeat 3 more times. Let rest 30 minutes. Repeat, letting rest another 30 minutes before starting the next step.
Pre-heat the oven to 225℃/450℉. Generously drizzle oil over a 9 inch square pan.
Tip the dough into the pan, pushing gently to the edge. Dimple by pressing your fingertips into the dough, working at an angle to form those classic bubbles.
Slice your brie and place on top of the dough. Let rest while the oven heats up.
Bake for 20 minutes - until the top looks golden and crispy.
After removing from the oven, but while still warm, brush with more oil and the honey. Top with fresh rosemary. Let cool before serving.
