Chocolate Hazelnut Babka Buns 16 Steps
Melt butter in microwave in increments of 15 seconds. When melted, add milk, sugar, egg and egg yolk. Save your egg white for your egg wash right before baking.
Mix together flour, salt and yeast in a bowl and create a well in the middle of the dry ingredients. Pour wet ingredients into well and use wooden spoon to mix.
Tip out of bowl and knead on lightly floured surface for about 6 minutes. You can also knead using dough attachment on a stand mixer for about 3 minutes.
Grease a bowl and place dough into bowl, cover with plastic wrap and place in warm place to rise for 1 1/2 hours.
To make filling, put all ingredients in bowl: chocolate-hazelnut spread, sugar, butter, cocoa powder, salt and dark chocolate. Place in microwave in 15 seconds increments until ingredients soften, begin to melt and can be mixed together.
When the dough has risen, place on a lightly floured surface and roll into a rough 25 x 40 cm rectangle.
Spread your filling on rectangle and fold the dough into thirds like a business letter so you end up with a roughly 25 x 14 cm rectangle.
Carefully transfer this onto a baking tray and place in fridge to cool and so everything can firm up.
After about 20-30 minutes in the fridge, cut the dough into 8 (25 cm long) strips.
Twist each strip along the length (think twirler) and coil around itself (think snail shell) and bring the last bit of length over the whole bun and tuck beneath.
Line a baking tray with parchment paper and arrange buns on tray. Lightly grease plastic wrap and cover your buns. Place in a warm place to rise for about an hour.
About 20 minutes before it is ready, preheat oven to 350°F.
Use your left over egg white with 1 tablespoon of water and brush over buns.
Bake for about 20 minutes until it is dark golden-brown in most spots.
You can eat warm or at room temperature.
Store in an air tight container and eat within 2 days or freeze and thaw before eating.
