"If you like lots of butter and cinnamon sugar topping go ahead and melt 6 tablespoons butter and use 1/2 cup sugar + 1 teaspoon cinnamon. I did not want a lot so the recipe as written is what I did. Adjust the topping amount to your likeness. If you make full-size muffins, cook for 15-17 minutes. Makes about 12 regular sized muffins...."
