The fruit gobbler:
This is really easy and fun! My oldest son, at four, helped me make the skewers (I cut off the sharp ends after we put the cheese and grapes on since we had younger children - they still went into the melon fine).
Gobble me up:
Seriously cute and all healthy too, my kids like laying out the apple and orange segments as feathers.
The candy corn and cookies are easy for younger kids to put in to help with this fun treat. We made these when my son was three and though they weren't picture perfect, he had a blast.
My kids and their cousins all really loved these. They are fun to make with your kids and add some festive fun to your gathering, not to mention they are all very yummy to eat! There are a lot more ideas on their website - check them out - appetizers and desserts/treats. (The names of each treat shown above are hot linked to the recipe.)
As far as standard recipes, I've also made the apple pie party dip with cinnamon chips many times (for whatever occasion) and it has been a HUGE hit... often requested by people (for me to make).
