On the bottom of a 9 x 12 inch baking dish, melt the 1/4 cup butter (1/2 stick). Add the brown sugar, syrup and nuts. Heat just until melted and spread evenly over the bottom. Turn off the heat. In medium mixing bowl, put the softened cream cheese, softened butter and powdered sugar. Whip until smooth. Open the rolls and separate. Take one roll at a time and either roll it out with a rolling pin, or stretch it into a 4" circle. Place about a tbsp. of the cheese mixture in the middle of the biscuit and roll into the shape of a log. Pinch the ends closed and put it seam side down into the baking pan on top of the brown sugar mixture. You should be able to fit 20 rolls in the baking pan with 10 being on each side. Bake in a preheated 350 degree oven for 20-30 minutes or until the top looks golden brown. Remove from oven and let stand for 1 to 2 minutes. Turn baking dish over onto a foil lined cookie sheet.
