*For a stacked tree:
If creating a stacked tree, trace varied sizes of circles, starting with 6-inch and on down to 1-inch for the top. Pipe the batter as above, using circles on parchment as a guide. Bake for 14 to 16 minutes for the larger circles and 10 to 14 minutes for the smaller circles, or until edges just begin to brown. Add a piece of Christmas candy to the top of the stacked tree. Dust tree with powdered sugar, if desired.
