Ingredients
- 160g + 30g plain flour
- 170 bread flour
- 45g + 100g caster sugar
- 2g salt
- 4 whole eggs + 4 egg yolks
- 60g water (more accurate than 120ml, as 1ml=1g of water)
- 14g instant dry yeast (about 2 sachets)
- 150g unsalted butter (important!!! room temperature and very soft)
- 300ml milk (full fat or semi-skimmed)
- 100g dark chocolate
- 1 tsp vanilla extract
- Combine 160g plain flour, 170g bread flour and 45g caster sugar together and mix
- Add salt to one side of the dry ingredients and yeast to the other side of the flour. Do not mix them, as it will kill the yeast
- Make a well in the middle of the mixing bowl, add water and 3 whole eggs into the mix and mix with dough hook on your mixer for 2-3 minutes on low speed until ingredients have combined
- Cut butter into 10-15 small cubes and add 1 cube at a time to the mix. Continue the mixer on low-medium speed
- Once all the butter has been incorporated, keep mixer on medium for another 15 minutes, the dough should become sticky and shiny
- Turn mixer speed up to medium high for another 2 minutes. You should hear the dough slapping against the side of the mixer at this stage. If the dough looks loose and wet, add 1 tbsp of plain flour and beat for another two minutes
- Seal mixing bowl with cling film and let it rise either at room temperature for 2-3 hours or in the fridge overnight. The dough should double to triple in size
- Whilst the dough is rising, make the pastry cream (creme patissiere). Beat the egg yolks, 100g sugar together really well
- Add plain flour and mix again until it thickens
- Heat milk to simmering point and pour into the egg yolk mix, whisking continuously!!!
- Pour all the contents back into the saucepan and keep it on medium heat and whisk continuously until it thickens (it's NOT going to go REALLY thick)
- Add vanilla extract to that pastry cream once it is thick
- Let it cool to room temperature (will take about an hour)
- Place a layer of cling film on table surface and lightly dust with plain flour
- Roll out the dough to a rectangle on cling film (approximately 50cm x 25cm)
- Spread the pastry cream evenly on the dough
- Break up the chocolate and sprinkle evenly over the dough and pastry cream
- Use the cling film to help roll up the dough, so the pastry cream and chocolate are inside
- Tuck in the sides, so the pastry cream and chocolate are not going to spill out
- Place a piece of baking paper on baking tray and layer your bread on it
- Seal the baking tray with cling film and let it rise again for another 90 minutes and it should increase in volume again
- After about 60-70 minutes of rising, pre-heat oven to 190 degrees C (170 fan) and place a small tray of water on the bottom of the oven (about 300ml), to reduce the bread from forming a hard crust surface as it bakes
- Remove cling film and beat 1 whole egg and brush egg wash on the dough
- Bake in the oven for 30-40 minutes, but water carefully, depending on your oven, it may take as little as 25 minutes
- Take out of the oven and let it cool for a couple of hours and slice into 10-12 pieces to serve
