For the filling:
Combine all ingredients and mix until combined well. Set aside.
For the dough:
Mix first 3 ingredients in a measuring cup and let sit for 5-7 minutes (it will get foamy).
Put the eggs, sugar, salt, and melted butter in the bowl of your mixer, adding the yeast mixture when it is ready.
Mix on medium speed (using the paddle) for 2 to 3 minutes, just until those ingredients are well mixed.
Change to your dough hook, turn the mixer on a low setting and slowly add the flour. Mix until the dough does not stick to the sides of the bowl. It will be soft, but not sticky.
Divide the dough into 8 equal parts. Using a rolling pin, roll into a a rough rectangle, 9x14 inches. Leave one of the long sides closest to you.
Spread a good scoop of the nut filling on the rectangle and spread the filling to about an inch from the edge.
Starting with the side closest to you, roll up the nut roll tight. Turn the edges in and pinch the entire seam shut.
Place rolls on parchment-lined baking sheet. Allow rise of 3 hours.
Preheat the oven to 350. Bake each pan individually for 25 to 30 minutes, or until the tops are a light golden brown. Cool completely before slicing.
