• In small bowl, combine water, yeast and sugar. Set aside for 10 minutes. Warm milk in microwave for 2 minutes. In a large bowl or heavy mixer combine milk, softened butter, salt and sugar. Mix together until butter is melted. Add eggs one at a time and 3 cups flour. Mix for 2 minutes. Add yeast mixture and 2 c. flour. Mix well. Let dough sit for 10 minutes. (If using a standing mixer...now is the time to change to a dough hook!)
• Continue to mix while slowly adding remaining 2 1/2 c. flour. Dough will start pulling away from the sides of the bowl, but is still quite sticky. Beat 3 more minutes.
• Coat another large bowl with 2 T. oil. Take dough out of mixing bowl and place in oiled bowl, turning over once to coat each side. Place clean towel over bowl and let raise in a warm spot for 45 minutes. After 45 minutes, put dough out onto floured surface. Knead by hand, adding a little flour if needed. DO NOT USE TOO MUCH FLOUR! You want dough to remain very soft!
• With rolling pin, roll dough into a rectangle shape about the size of a jelly roll pan (11x15 inch) and 1/2 inch thick. Melt 1/3 c. butter in microwave for 30 seconds or until just melted. Spread over dough. Sprinkle 1/4 c. sugar and 3/4 c. brown sugar over butter. Sprinkle cinnamon on top of sugars. Drop little spoonfulls of the Biscoff spread over the dough using a small spoon (we used a baby spoon). Don't spread the Biscoff-- just leave the little dollops as they are.
• Top with nuts if desired.
• Roll up starting with the long side; pinch seam to seal. Cut into 1 inch rolls and place on greased cookie sheet. Cover and let rise another 45 minutes. Bake at 350 degrees for 16-20 min. or until lightly browned. Cool for 10 minutes before frosting.

For the frosting:

• In a medium bowl, mix cream cheese, Biscoff spread, butter, and vanilla until smooth. Slowly add powdered sugar until desired consistency. Spread over warm cinnamon rolls.
