Lightly grease a large bowl with baking spray and place the dough in the bowl. Cover with plastic wrap and place a warm, damp towel on top. Rise on the counter or in a warm place for 1 1/2 – 2 hours or until the dough doubles.
Spread the softened butter onto the dough. Then mix the brown sugar, cinnamon, and salt in a bowl, sprinkle this all over the butter, and press/rub it into the butter.
