Transfer dough to lightly floured surface. Use hands to press down excess air.
Leave as one large dough or equally divide into two halves.
Roll dough into a ½ inch thick rectangle.
Using rubber spatula, coat dough with softened sunflower butter. Leave a bare ½ inch rim around the edges.
Generously sprinkle the sunflower butter with cinnamon sugar.
Roll the dough inwardly from the long side to create a log with an inner cinnamon swirl.
For the long loaf, transfer gently to the prepared loaf pan and tuck the ends under the center to fit.If you are making the two short loaves, I like to very gently take my hands on both ends of the log and softly cup the dough back into a shorter, thicker log. Then lift the roll and place perfectly into the loaf pan.
Cover your bread log(s) loosely with a tea towel and place in warm location to double in size for a second time. (1 hr)
Preheat oven to 350 F.
Uncover puffed loaf(s) and brush with egg wash.
Sprinkle with roasted sunflower seeds.
Bake on middle to lowest rack for 30-35 minutes for two loaves or closer to 40 minutes for one large loaf.
The loaf is baked when it reaches an internal temp of 190 F, or sounds hollow when tapped in the bottom with your finger.
Place pan(s) on cooling rack for 10 minutes before lifting loaves out.
Slice and serve warm!
