I always admire the holiday projects Megan at Not Martha comes up with (remember these gingerbread houses that perch on the edge of a mug?). But she's outdone herself this Halloween, with trick-or-treat cookies with, yes, a trick or a treat inside! Megan always seems to do her most creative projects at Halloween, like her Tentacle Pot Pie, and Meat Hand. (Gory!) But I really love these little cookies the best out of all her projects, I think. They're in the shape of pumpkins, coffins, and ghosts, and the trick is to sandwich the cookies together with enough stiff icing to create a hollow pocket in the middle. (They're based on the now-infamous Piñata Cookies at SheKnows.)
Megan filled some with some spooky treats (sugar ants) and others with a sweet surprise (mini M&Ms). You have to break the cookie open to find them!
This looks like a decent amount of work, but how fun!
