Now that the dough has increased in size, transfer it back into a clean, floured surface and roll it into a 9 by 15 in length approximately.
Next, brush the dough with melted butter to within about 1/2 inch of the edge. It’s essential to leave a bit of a border to seal the roll, sprinkle the cinnamon mixture all over the dough, and roll it up toward you! Make sure to gently tight each roll until all the dough is rolled into a log. Gently press the sides of the log to seal.
Using a good knife, slice the log in half, lengthwise into 2 pieces. This will expose the flavorful cinnamon filling.
Then, twist these two pieces together, creating a beautiful braid. Gently, transfer the loaf into the baking pan (loaf pan) and tuck the ends of the braid under the loaf if needed. Let it sit on the counter uncovered for 30 minutes allowing the log to rise.
