Transfer mixture to a large piping bag fitted with a large plain tip. Pip 10 evenly spaced mounds (Each about 2 1/4 inches in diameter and 2 inches high) onto parchment in a circle, using traced ring as guide. With the back of a spoon, create a hollow in each mound. Bake until ring easily lifts off parchment, about 1 hour, 10 minutes. Turn off heat; let stand in oven for 1 hour.
