2 ingredient frozen graham cracker sandwiches, or “grammy sammies,” are a fantastically easy and delicious summer treat!

Talk about a blast from the past! As a kid, I spent my summers outside in the hot sun or swimming at the neighborhood pool. One of my absolute favorite snacks was the grammy sammie, a frozen pudding and graham cracker sandwich that my mom would make in all sorts of flavors.
I’d forgotten about this wonderful little dessert until I attended a friend’s party a few weeks ago. Someone had created their own take on this — an unfrozen graham cracker and frosting version that jogged that latent memory. I had to make a few sammies using my mom’s recipe when I got home, just to make sure that they were still as good as I remembered. Surprise! They really, really are.
Aside from the nostagia and the deliciousness of these simple snacks, there’s a lot more to like. For one, these take about 15 minutes of hands on time. For another, they’re cheap. Where I live, graham crackers will cost you about $1.85. The pudding runs $0.72. Since you can get 2 batches from the graham cracker box, the cost of each sammie comes to $0.10. There are not many snacks I can think of with that low a price tag!
They’re also low-calorie. Where else can you get a treat that tastes like an ice cream sandwich for only 100 calories?
What do I need?
Graham Crackers: Cinnamon, chocolate, honey, or gluten-free, you have variety in crafting a flavor combination of your choice. Each cracker sheet makes 1 standard sammie. You can also split those in half to make mini-sammies for dessert trays or smaller children.
Instant Pudding: This could really be done with any type of prepared pudding, but the recipe below uses a 3.5 oz package of instant pudding mix . Any flavor of pudding will work with this. You can mix and match with your graham crackers to create a wide variety of frozen deliciousness!
Sprinkles, drizzle, candy bits, etc: These optional additions can be used to roll the sides of your sammies, or sprinkle or drizzle on top. The ones in the pictures in this post have been drizzled with white chocolate or sprinkled with festive 4th of July sprinkles for a party!
How do I store frozen grammy sammies?
If you think you’ll eat them quickly, you can simply put some plastic wrap over the pan you made them in.
My favorite way to keep them long-term is to individually wrap each frozen one in Saran wrap and then place them into a freezer or Ziploc bag. This way, I can dole them out to the kids easily, and they will keep for up to 1 month in the bag without developing freezer burn.
The trick to this is to make sure that the sammie is frozen before you wrap them, otherwise the wrapping process will squish your sammie and create a gooey mess.
