Incredibly soft and fluffy chocolate buns made with buttery brioche dough and chocolate chips. They make an easy breakfast, handy lunchbox filler, or a delicious sweet snack.
In a small bowl, combine the lukewarm milk and instant yeast and stir thoroughly. Set aside for the yeast to activate (bloom).
In a large mixing bowl, combine the flour, sugar, and salt. Add the yeast mixture, the whisked egg, and vanilla extract. Mix everything with a handheld electric mixer or stand mixer with a dough hook on medium speed for about 5 minutes. The dough needs to be smooth and pass the windowpane test.
Cut the butter into 1-inch cubes and knead it into the dough one after another on low speed.
Scrape down the sides of the bowl and form a large ball of dough. Cover the bowl with a damp kitchen towel or plastic wrap. Let it rest in a warm spot for 45 minutes for the first rise.
Transfer the soft dough to a lightly floured surface, roll it out into a 9x9 inch square using a rolling pin, and add the chocolate chips evenly. Roll the dough up from one end and cut the roll into 8 evenly sized portions.
Using your hands, roll each portion into an 8-inch log. To make the knotted buns, start by creating a U shape with the log. Twist the two top ends around each other twice. Fold the twisted top down into the hole and tuck it in. Place it on a lined baking sheet and repeat the process for the other buns.
Cover with a tea towel and let the rolled buns rest for about 15-20 minutes for a second time for the final proof. Meanwhile, preheat the oven to 350F (180C).
Brush the chocolate chip brioche buns with the egg wash and bake them in the preheated oven for 20 minutes until golden brown. Let them cool down a little and serve them warm!
