I love these:
And while I wouldn’t call anything involving mini marshmallows “healthy”, it is Halloween after all – and at least you’ve got apples and nut butter, no?
This would work just as well with Nutella or speculoos (homemade if you’re feeling it) too.
Vampire “Teeth” (makes 8; may be doubled or tripled)
from Martha Stewart
1 Granny Smith apple
Any nut butter
Core apple; cut into 16 wedges and spread one cut side of each with some of the nut butter. Press six marshmallow “teeth” and two almond “fangs” into the nut butter on one wedge, then top with a second wedge.
