Grandma’s Three Layer Cookie Bars Recipe
This recipe is very special to me.
I have an old newspaper clipping from our local paper. My grandmother was recommended for the “Recipe of the Week,” and this is the recipe that she submitted. It quotes her as saying that “her family likes these “no baking” confections and she always makes them at Christmas and cuts them small and dainty.”
Grandma’s Three-Layer Chocolate Squares have stood the test of time in our family. My mom continues the tradition at Christmas time with these treats.
Three Layer Cookies
I’m not sure if mom does it for nostalgia or if it’s because they are so yummy.
Or, maybe it’s because these 3 layer cookie bars can be made a month ahead of time and kept in the freezer. Wrap tightly and pull them out when you are ready to serve. My mom waits to cut them right before serving. Being able to make them ahead is key for a mom who goes above and beyond with her Christmas baking (Chocolate Crinkles Cookies, Poppy seed Bread, Dainty Log Butter Cookies, Fantasy Fudge, Crock Pot Seven Layer Bars, Glazed Pecans, Homemade Caramel Corn, and Chocolate Nut Cookies are some of our favorites).
While you can make them ahead, they are AMAZING served fresh. You can cut them in quite small squares because they are rich and a bite of them with a cup of coffee is the perfect treat.
Old Fashioned Triple Layer Cookies
I recently made these with my two young daughters. It is the perfect recipe for kids to help with as the list of tasks they helped with was long and included:
- crushing graham crackers that are inside a zip-lock bag with rolling pin
- sifting powdered sugar
- unwrapping butter
- cracking egg
- measuring most ingredients
- pressing the bottom layer of cookie into the pan
- whisking second layer gently
- spreading cream layer over base
- unwrapping and breaking up Hershey’s bars
Molding young kids into future home cooks is something that you can be doing with your kids, grandkids, nieces and nephews. Help them gain confidence in their skills. Let them make messes. And have fun! I am hoping my kids will cherish these memories as I do with my mom and grandmas.

How to Make Triple Layer Cookie Bars

Recipe FAQs
- Sift the confectioners (powdered) sugar after measuring for the first layer of these 3-layer cookie bars.
- How many cups are in a package of graham crackers? The answer is approximately 1 1/2 cups per plastic package that is found inside the graham cracker box. This recipe calls for 2 1/2 to 3 cups of graham cracker crumbs, so use 2 of the small plastic packages (a box of graham crackers usually contains 3 plastic packages inside).
- To easily make graham cracker crumbs, use a food processor like this one or use a rolling pin. I recommend the latter; its a great stress relief.
- Grandma’s original recipe calls for 9 3/4 ounces of “sweet chocolate bar” or she says you can substitute chocolate chips. It just so happens that 9 3/4 ounces = 6 Hershey’s bars. How convenient is that?
- To melt the Hershey’s bars, put in a double boiler. What is a double boiler? It’s a special pan that is two saucepans on top of each other. What do you substitute for a double boiler? Find a glass bowl that fits on top of a saucepan, and then fill the saucepan with a couple of inches of water but do not have the water touch the bottom of the bowl. Bring the water to a gentle boil underneath the bowl of chocolate, and the heat will melt the chocolate perfectly.
- The easiest way to spread the cream layer (2nd), and Hershey’s layer (3rd) is with an offset spatula like this one.

What is confectioners sugar?
Don’t be confused! Confectioners sugar is powdered sugar. You would not want to substitute plain white sugar for confectioners sugar. Powdered sugar is much finer and sweeter than plain white sugar.

These bars look so rich and gooey, addictive they must be!
Makes me nervous with eggs and not baking it – you never had any issues with raw eggs ?
Many old-fashioned recipes call for eggs that aren’t cooked. We personally haven’t had an issue in all the years we’ve made these but it is up to your own personal judgement whether you want to try it. You could use a pasteurized egg product instead or even applesauce or mashed bananas as a substitution!

Has anyone tried baking these bars? I’ve baked graham cracker crusts without egg so I’m wondering what effect baking would have with the egg in this crust. I think I’m going to try it as I’m not comfortable with serving a dessert with raw egg to others. I’ll come back and post how it worked when I get around to making them. Also, would omitting the pecans change these too much? I know a couple people who have nut allergies. Thanks!
