endless swirls of rich dark chocolate filling layered between buttery yeasted cake
In a large bowl, combine the flour, yeast, salt, and cornstarch. Whisk to combine. Make a well in the center of the bowl, then add the melted butter, eggs, avocado oil, milk, and granulated sugar. Stir with a wooden spoon to combine. When the mixture becomes thick and sticky, start mixing by hand. Pinch to incorporate the ingredients.
Begin kneading the dough in the bowl, by hand, until it becomes fairly smooth, and forms a ball. This should take about 3 minutes of kneading.
Cover the bowl with plastic wrap, and let the dough rise at room temperature for about 1.5 hours or until it has doubled in volume.
Make the Filling:
In a medium size bowl, add the softened butter, cocoa powder, brown sugar, salt, and melted semisweet chocolate Baking Portions. Use a spoon to combine until the mixture is totally smooth, with no lumps remaining. Set aside.
Dust a large work surface generously with flour. Pour the risen dough out into the work surface, and use a floured rolling pin to to roll the dough out into a large rectangle that is approximately 20” long and 14” wide, 1/4” thick. Spoon all of the chocolate filling out onto the rectangle of dough.
Use an offset spatula to gently smooth the filling out into an even layer, leaving a 1/2” border on all sides. With the long edge facing you, begin rolling the dough up tightly into a log.
