Pre-heat the oven to 400°F. Grease a 9-10 inch pan with cooking spray and set aside.
Add the cottage cheese, sugar, buttermilk, melted butter, and vanilla in a food processor. Pulse until smooth, about10 seconds. Then add the flour, baking soda, salt, and baking powder and pulse in short bursts just until the dough sticks together (The dough should be soft and moist.)
Remove dough and place on a lightly floured surface.
Flour your hands and knead dough lightly about 4-5 times until smooth.
Roll the dough lightly with a rolling pin to about 12x15 –inch rectangle
Brush the whole dough with melted butter. Leaving a 1-inch border on cinnamon dough, sprinkle with brown sugar mixture. And pat gently into the surface. Place the nuts over the sugar mixture.
Starting with the end nearest you, roll the dough up snugly like a jellyroll around the filling, finishing the roll with the seam side down. Do not forget to pinch the seal so they don’t come apart when making the dough.
Slice the roll into 4 equal pieces, then slice each piece into 6 equal pieces
Separate wedges and place on prepared baking pan cut side up. Brush
Bake at 400° for 20-28 minutes or until lightly browned and firm to touch. Let it rise for 5 minutes, remove the spring form ring and transfer to serving plate
