Instructions

1. In the bowl of your stand mixer, whisk together 2 cups of the flour, the sugar, salt, ground cardamom and yeast. Switch to the dough hook attachment.
2. Warm the milk to 120-130 degrees Fahrenheit. Add the butter and let it soften in the warmed milk. It doesn't have to melt completely, you just want it to be very soft. Then add this mixture along with the beaten egg to the dry ingredients. Beat on medium speed for 1-2 minutes, scraping down the sides of the bowl as necessary. Once the mixture is well combined, start slowly adding in more flour, about 1/4 cup at a time, until the dough is soft, easy to handle and easily leaves the side of the bowl. You'll need anywhere between 1 to 1 1/4 cups flour.
3. Mix the dough on low-medium speed for about 5 minutes, pulling the dough down off the hook as needed. The dough should be smooth and elastic. Alternatively, you can knead the dough by hand on a lightly floured countertop for about 5 minutes.
4. Gather up the dough with your hands and shape it into a ball. Transfer it to a lightly oiled bowl, turning the dough to coat it with a thin layer of oil on all sides. Then cover the bowl loosely with a thin kitchen towel and let the dough rise in a warm place for 1 to 1 1/2 hours, or until roughly doubled in size.
5. Once the dough has risen, gently punch it down to deflate it. Remove it from the bowl and transfer it to a floured countertop. Then shape it with your hands into a rectangle. Next, use a rolling pin to roll the dough out into a 24 X 12-inch rectangle. This will take a little bit of time, because the dough can be fairly elastic and "springy" at first. If it's bouncing back too much, let the dough rest for a few minutes, then try rolling it out again.
6. Once the dough is rolled out, make the filling. In a small bowl, stir together the sugar and cardamom and set it aside. In a separate microwave safe bowl, microwave the butter and chocolate-hazelnut spread for 20-30 seconds, or until the two are just soft enough to be well combined.
7. Spread the softened butter/chocolate-hazelnut mixture out in a thin layer evenly over the surface of the dough, leaving about a 1/2-inch boarder around the edges. Then sprinkle the sugar/cardamom mixture evenly over the top. Finally, top with the orange zest.
8. Beginning at one of the long edges of your rectangle, tightly roll up the dough into a log. Then pinch the edges of the dough together to seal the log as best you can.
9. Spray a baking sheet and the ring of a 9- to 10-inch springform pan with non-stick cooking spray and set them both aside.
10. Using a sharp knife, slice the roll lengthwise, creating two equal sized long halves, but leaving one end still attached by about 3/4-inch at the very end. Slightly rotate the halves outwards so the layers are facing upwards. Then starting from the end that is still attached, cross the two halves over each other. Continue doing this until you end up with a single twisted/braided rope. Pinch together the end of the rope.
11. Gently slide the rope onto your greased baking sheet. Starting with one end, spiral the rope into a closed circle. The circle doesn’t have to be tight, because the bread will rise and puff up as it bakes, filling in any small spaces. But it shouldn’t have a large hole in the center, either (think about making a shape that resembles a snail shell, not a wreath). Tuck the very end of the rope under the circle so it doesn't stick out.
12. Place the ring of your springform pan over/around the dough circle to contain it. Then cover loosely with a thin kitchen towel and let the dough rise in a warm place for 30 minutes.
13. Meanwhile, pre-heat your oven to 350 degrees. Position an oven rack in the middle position.
14. Remove the kitchen towel from the dough, but leave the springform pan in place. Transfer the baking sheet to your pre-heated oven and bake for about 30 minutes, or until the bread is golden brown and puffed. Then remove the baking sheet from the oven and allow the bread to cool for 10-15 minutes before carefully sliding it off onto a wire rack to continue cooling.
15. While the bread cools, whisk together all of the ingredients for the glaze. Then drizzle the glaze over the bread before slicing and serving.
16. This bread is best when it's enjoyed the day it's made. Leftovers can be stored in an airtight container at room temperature for about 2 days, and re-warmed slightly before eating.
