Ever since I saw a recipe for Chocolate Pretzel Rings in a Taste of Home magazine (about 12 years ago), I have made them every Christmas. My kids always help make them and they are so addicting to eat. I usually get a large bag of M&M's and Hershey kisses from Sam's Club plus 3 or 4 bags of pretzels and make a ton of them.

Sometimes the round pretzels are hard to find but I can usually find them at Walmart.
An alternate to these would be using the waffle pretzels topped with a rolo and a pecan half. I've never made them because my kids don't like nuts but I have heard they are yummy.
I love the Ritz crackers with the peanut butter and dipped in chocolate. My mom started making them about 30 years ago too and they are so yummy. If you like the Girl Scout peanut butter patty cookies (also known as Tagalongs), you will like these.
And being from the Buckeye State, I absolutely love Buckeyes too.
Another idea is cake balls (you can easily find recipes when you do an internet search). They are a big hit on another MB that I read. I made them once. My kids loved them but I thought they were too sweet.
