For the dough:

1. In the bowl of your mix master fitted with the dough hook, combine milk, honey, and yeast. Let it rest for a few minutes until the yeast begins to bubble. Add the flour and salt and mix on medium-low speed, just until the dough comes together. Add the butter and egg yolk. Mix again on low speed until everything is incorporated. The dough should be a little sticky.
2. Place the dough in a buttered bowl, cover with a towel and let rest in a warm, dark place for at least 2 hours or until the dough has doubled in size.
3. Butter an 8-inch cake pan, line the bottom with parchment paper and butter again. Set aside.
4. On a lightly floured surface, transfer the dough and roll out into a 12" x 4" rectangle. Use a pizza wheel to then cut the dough lengthwise into four strips, then cut vertically so you should have about 30-32 pieces. Roll the dough pieces into rounds and fit into the prepared cake pan.
5. Brush each dough with the melted butter, turn and brush the other sides. In a small bowl mix together the cinnamon sugar. Dip each dough ball into the cinnamon sugar and return to the cake pan.
6. Set the cake pan aside and let the dough balls rise again for about 1 hour.

For the Streusel:

1. While the dough is rising, prepare the streusel. Using the leftover melted butter that we brushed the dough balls with, combine in a small bowl with flour, brown sugar and cinnamon. Mix until all is combined. If you feel the streusel is too wet add another spoonful flour. Set aside.

For the Sauce:

1. Before you begin on the sauce, preheat the oven to 350 degrees F.
2. Melt 3 tablespoons of butter and let cool slightly. Whisk the butter together with remaining cinnamon sugar and cream until it is well combined. Pour the sauce over the risen dough balls.
3. Top it off with the streusel. Transfer the bread onto a baking sheet lined with parchment as it may bubble over while baking.
4. Bake for about 45 minutes or until the top is golden.
5. Transfer to a wire rack and let cool slightly. Transfer the bubble bread over onto a serving dish. Drizzle with warmed caramel is desired. Serve immediately and enjoy!
