This is a great snack that we often enjoy when taking a walk or going on a road trip. They can be a little messy, but they are delicious and my kids love them. Be creative. We like Granny Smith apples best, but use what you like. The amounts and ingredients are a little vague, but you get the idea. The recipe says to core the apples, but to leave the bottoms in tact. We just core them through, but that's why they are a little messy. I might try placing all the filling ingredients in a plastic bag or cake decorating bag and squeezing it into the cored apple. We love these take-along treats. UPDATE: Turn these into a goulish treat by partially inserting a juicy gummy worm!
