You'll be amazed by this super easy Brioche. Made with your sourdough starter, it has great flavor, deep color, and a rich texture. Be prepared to impress and be impressed!
In a little bowl, add your yeast mixture ingredients and let sit under a clean towel for 10 minutes or until frothy.
In the bowl of your stand-mixer, add the flour, sugar, 2 eggs and yeast mixture.
Mix on low-medium speed for about 1 minute.
Add the butter, piece by piece.
Once the butter is incorporated, add your sourdough starter.
Mix on medium-high speed for 1 minute and finally add your salt.
Continue mixing until all is incorporated. Mix on full speed if needed.
While your stand-mixer is running, preheat your oven at 120°F (50°C) and grease a bowl (or you can leave the dough directly in your stand mixer.)
When your dough starts to come off the bowl, you can stop mixing.
Turn off the oven.
Transfer the dough in your greased bowl if using, and cover the bowl with plastic wrap.
Place the bowl in the oven and close the door.
Let rise for about 1 h 45 or until doubled in size.
Remove the bowl from the oven and with a rolling pin roll the dough out on a well-floured surface.
Roll out in a rectangle (size doesn't matter, just roll out until you reach the desired thickness without tearing the dough apart.)
Fill with filling of your choice, and roll the dough like you'd do for cinnamon rolls -with the smaller side- and place in a greased bread pan.
Again, put plastic wrap on or a towel.
Put back in the oven (turned off!) for 1 hour or so.
Remove the pan from the oven and preheat at 350°F (180°C) for 10 minutes.
Meanwhile, brush the dough -twice if you can- with egg wash (egg+milk+pinch of salt).
Put the pan back in the oven and let bake for about 35-45 minutes, or until a deep golden brown -check the next picture for a visual- Enjoy!
