In a small bowl, melt the butter in the microwave or on the stove. Then, in another small bowl, mix the remaining ¼ cup of sugar with the cinnamon. Once the butter is melted, pour it evenly over the top layer of crescent dough. After that, sprinkle the cinnamon-sugar mixture on top, making sure to cover it generously. This step creates that gorgeous crispy topping that everyone loves about Sopapilla Cheesecake.
