Pumpkins? Not quite right.
CAKES?!? Now, why didn't I think of that before?!?
To make the star cake cookies, you'll be putting to shapes together, like this:
Cut out tiered cakes and small stars...
...use the star cutter to cut out where you want to place the star on the cake...
...place the star in the cut-out and freeze for 5-10 minutes before baking.
(You DO freeze your cookies before baking, right?)
For the double-decker cookies, you'll put those together just like these double-decker valentine cookies.
For the star-topped cakes, just outline with a #2 tip and black icing.
After an hour, fill in the outline with thinned white icing. Let the icing dry for at least one hour.
Again with the #2 tip, go over the outline of the star and pipe "bunting" across the cake. Fill in the bunting with red and blue icings. (Piping consistency icing is fine here...flood icing in tiny spaces has a tendency to collapse.)
Place small star sprinkles on the bunting with tweezers, or place on and nudge gently into place with a toothpick.
Happy birthday, America!!!
