Walnut Oh Henry Bars. A scrumptious no-bake cookie bar with a caramely, nutty centre sandwiched between graham crackers and topped with sweet vanilla buttercream frosting.
These Walnut Oh Henry Bars were a staple recipe in all the old church cookbooks I knew as a kid when I first started baking. Here in Newfoundland, like all across Canada, these congregation-member submitted recipe books have long been a popular fundraiser for church groups.
I remember the Anglican Women’s Cookbook from St. Luke’s Church in Port-de-Grave from 1974 when we lived there for a year. My Mom’s Chocolate Chip Cookie Squares being published with her name right beside the recipe.
I might have 3 cookbooks in print now (UPDATE NOW 5) but I guess it was Mudder who was the first published recipe writer in this family. HA!
We also owned another couple of these cookbooks. I remember the United Church Women’s Cookbook in Coley’s Point as being one of them.
Mudder probably still has them all at my parents house.
Some variation of this recipe always seemed to be in the “Squares” section of each book and it always confused me a little.
The name Oh Henry Bar I assumed to be taken from the popular candy bar of the same name. However, the cookie bars are nothing like it.
The candy bar has peanuts and no biscuit element. Whereas, this recipe uses walnuts and the filling is sandwiched between Graham Wafer Crackers.
I don’t know how that name came to be, but regardless they are still a favourite. Especially at Christmas time. There always seemed to be a batch in the freezer when I was growing up.
The recipe is a bit flexible. If you don’t like coconut, omit that and add a few more nuts to the mix.
Back when I was a kid, we used ground nuts in this recipe. I remember loving the old fashioned nut grinder with crank on the side that you turned to turn the nuts into crumbs.
Today I prefer to get the crunch of the nuts in the cookie bars so I only roughly chop them or even crack the individual nuts into large pieces by hand.
As for the nuts, if walnuts are not your thing, any toasted nuts you like are easily substituted to personalize your own favourite version.

Walnut Oh Henry Bars
Walnut Oh Henry Bars - a scrumptious no-bake cookie bar with a caramely, nutty centre sandwiched between graham crackers and topped with sweet vanilla buttercream frosting.
Ingredients
- Graham crackers, enough to line a 9x13 pan twice
- 1 1/2 cups firmly packed brown sugar
- 3/4 cup butter
- 3/4 cup milk
- 1 1/2 tsp pure vanilla extract
- 1 1/2 cups roughly chopped toasted walnuts
- 1 1/2 cups dried unsweetened coconut, medium cut
- 2 cups graham cracker crumbs
For the Vanilla Buttercream Frosting
- 2 cups icing sugar, powdered sugar
- 1/3 cup butter at room temperature
- 1 1/2 tsp pure vanilla extract
- 2 tablespoons milk
Instructions
- Line the bottom of a 9x13 pan with a single layer of the graham cracker, cutting them to fit around the edges. You will need another identical layer fro the top.
- Toast the walnuts in a single layer on a pan in a preheated 350 degree oven for 10 minutes. Toss them once at the 5 minute mark. Allow them to cool to room temperature before roughly chopping them with a chefs knife or individually breaking them into a few pieces each with your fingers. larger chunks are better in this recipe, I think.
- In a medium to large saucepan over medium heat, add the brown sugar, butter, milk and vanilla extract. Bring to a slow rolling boil for about 4 minutes. Turn the heat down if necessary. This should never boil too rapidly.
- Remove from heat and stir in the nuts, coconut and graham crumbs.
- Spread this hot mixture evenly over the graham cracker base and then top with an additional layer of graham crackers.
- Allow to cool to room temperature before placing in the fridge for a couple of hours at least to set completely.
- Top with the vanilla buttercream frosting, cut in squares and serve.
To prepare the frosting
- Cream together all of the frosting ingredients until smooth and spreadable. It's okay to add a little more milk if needed but the thicker the frosting consistency the better. If it gets too soft, just add a couple pf heaping tablespoons of icing sugar.
Notes
For the graham crumbs I usually buy a large box of the crackers, hold back enough to use on the top and bottom layers and then grind the rest in the food processor to use in the filling. This keeps me from having to buy the crackers and crumbs separately.

Perhaps the name is from the American writer O. Henry, pen name. Aka William Sydney Porter, 1862 - 1910.

I had never heard of these but hubby bought a 4pk of graham cracker boxes at the big box store for some odd reason so I was looking for something to do with them. They were very fresh and crispy so didn't seem to soften much with the walnut mix. Toast those walnuts, other recipes don't call for that but it really elevates this recipe!!! I opted for a looser and thinner glaze type icing (less butter) and that worked beautifully to bring these together. This is going to be a go to recipe for me from now on. Thank you
