These maple walnut squares are delicious, sweet bites, with tons of maple flavour in the filling, lots of walnuts and a crispy shortbread crust.

Maple walnut squares are a classic sweet treat, with a shortbread base, a sweet, maple filling and lots of walnuts. They set up beautifully, so they cut nicely and are perfect for anything from a bake sale to a BBQ to a sweets table. (And they taste a lot like butter tarts, which is always a good thing :)
While these are sweet, they are not over-the-top sweet. The nuts do a great job of tempering the sweetness, especially slightly bitter walnuts.
Ingredients and substitutions
A few notes about the key ingredients …
Walnuts – you can use walnuts or pecans for the squares. Sometimes I like to use a combination of pecans and walnuts. Use what you have or prefer.
Maple Syrup – real maple syrup is highly recommended. Specifically, I love to use Amber or Grade B maple syrup, which has the strongest maple flavour.
How to make maple walnut squares



- Start by adding all of the crust ingredients except the butter to a medium bowl. Stir together well.
- Add the cold butter pieces to the bowl.
- Use a pastry cutter or two knives to cut the butter into the flour mixture until the butter pieces are no larger than pea-sized.



- Prepare an 8-inch metal baking pan by spraying with cooking spray and lining the bottom and two sides with parchment paper.
- Pour the crumb mixture into the prepared pan.
- Press the crumb mixture into the pan firmly and evenly.



- The crust is now ready to pop into the oven for 18-20 minutes.
- While the crust is baking, whisk together the filling ingredients except the walnuts.
- Set aside the filling mixture and measure out the walnuts.



- Once the crust comes out of the oven, scatter the walnuts over the top of the hot crust.
- Pour the filling mixture over the nuts.
- Return the pan to the oven and bake until the squares are set, about 30-35 minutes.
Recipe tips!
- If the neatness of squares is important (for presentation), once cooled, remove to a cutting board and cut off all the edges by about 1/2 inch, then cut the remaining piece into equal squares.
- Refrigerating the squares before cutting will make for neater slices.
- If you like the sweet/salty combination, sprinkle some finishing salt (like Maldon’s/Fleur de Sel) on top as soon as the squares come out of the oven.

Storing and freezing
I like to store these squares in the refrigerator, but they are most delicious at room temperature, so take them out of the fridge for a bit before serving. These should also freeze well for a couple of months.

Ingredients
Crust:
- 1 cup all-purpose flour, spooned and levelled
- 1/4 cup white granulated sugar
- 1/4 teaspoon salt
- 1/2 cup butter, cold, and cut into 8 pieces
- 1/4 cup walnuts, finely chopped (or pecans)
Filling:
- 2 large eggs
- 1/2 cup brown sugar
- 2 Tablespoons all-purpose flour
- 1/2 teaspoon salt
- 3/4 cup pure maple syrup
- 1/4 cup heavy whipping cream, 35%
- 1 Tablespoon vanilla
- 2/3-3/4 cup walnuts, chopped (or pecans, or a mixture of both)
Instructions
- Preheat oven to 350F (regular bake setting/not convection or fan-assisted). Line an 8-inch metal square baking pan (preferably with straight sides) with parchment paper, leaving an overhang on at least two sides, to use as handles to lift the squares out of the pan later.
- In a medium bowl, add the flour, sugar, salt and walnuts. Add the cold butter pieces and use a pastry cutter or two knives to cut the butter into the flour mixture until the butter pieces are no larger than pea-sized. Pour the mixture into the prepared baking pan and press firmly and evenly into the pan.
- Bake the crust in the centre of the preheated 350F oven until golden and set, about 18-20 minutes. Remove from oven, but leave the oven on.
- While the crust is baking, whisk together all the filling ingredients except for the walnuts and set aside. Measure out the walnuts and have ready.
- Once the base crust is out of the oven, scatter the walnuts evenly over the top of the crust. Re-whisk the filling, then pour the filling over the nuts and crust. Use a fork to evenly distribute the nuts floating on top, if necessary.
- Place into the 350F oven and bake until filling is set and the top is deep golden, about 30-35 minutes. Cool completely in the pan on a cooling rack, then carefully lift out of the pan using the parchment paper edges. (I like to refrigerate for a bit before cutting into squares, just to make the whole process neater, but the squares are quite sturdy without refrigerating, once cooled.) Cut into squares. Eat as is, or serve on a dessert plate with a dollop of whipped cream and a scattering of nuts.

Hi! I’m Jennifer, a home cook schooled by trial and error and almost 40 years of getting dinner on the table! I love to share my favourite recipes, both old and new, together with lots of tips and tricks to hopefully help make your home cooking enjoyable, stress free, rewarding and of course, delicious!
These were our Sunday dinner dessert (the only night I make dessert) and they were very good. Since my son does not eat lactose, I used a soy based butter substitute and coconut milk instead of the dairy ingredients and it worked out well. Thanks for a great recipe!
Glad to hear you enjoyed them, Vivian and good to know that the lactose-free substitutes worked so well :)
Planned on making the maple syrup skillet pudding cake receipe this weekend but didn’t have 35% whipping cream, so I just switched recipes! Followed your instructions to a tee. Used all pecans & 10% cream (what I had on hand). The squares turned out delicious – not overly sweet like butter tarts. And much easier to make! You said 12 sevings but we ended up with less. Guess we were being pigish!
So glad you enjoyed them, Irene and nothing wrong with big squares :)
Hi Jennifer, again, a fantastic Maple Syrup recipe. I just had to put the first batch in the freezer to make me stop eating ;-). Delicious! Makes this Dutch girl very happy and longing for a good Canadian Summer this year!
So glad you enjoyed them and I do the freezing thing too. It doesn’t totally stop me, but it does slow me down ;)
Oh, oh, oh! I’m so sorry for saying ‘in the US’.
No worries :) We’re one big happy family here in North America!
Yay! I adore maple everything but maple products are very expensive here (if you can find them at all…I still yearn for proper maple candy) so reliable recipes are a must. The last time I made a maple slice it was very crumbly and hard to cut so I’m looking forward to giving this one a go. I love the idea of finishing it with a few salt flakes, too. I think it’s a rare find in the US, but if you ever happen to come across Murray River Pink Salt flakes, grab them and run. There will always be a place for Fleur de Sel, but I swear you’ll ditch the Maldon forever.
Maple syrup is expensive here, too (and we make a lot of it here in Canada :). These are very easy to cut. As I mention in my post, I like to refrigerate them a bit before cutting, just to make it that much easier to get a nice neat cut. As for the salt, I will definitely keep my eyes peeled for that pink salt. I am a huge sweet/salt fan, so I love to try different salts. Thanks!
What decadent squares, the maple and walnut pairing sounds divine!
Thanks Laura :)
Hi
I made this one today. If I can show picture that I made , I’d like show you . Because exactly same as your picture !
Again, it is so delicious and flavor are delicate. Bottom of crust are so not so dry at all, and when you are eating still crunch on your mouth .
Well, you did again ! This is my favorite repeat recipe !!
Thank you !
So glad you enjoyed these, Yuri! They were a big hit here and didn’t last long :)
I brought a big jug of maple syrup with us when we moved from New England to Florida. This recipe sounds like a great way to use some of it.
Thanks Karen and yes, these are very worthy of your maple syrup :)
I much prefer bar cookies to drop cookies, it’s so much less work. This flavor combination sounds so amazing!
Thanks Sara :)
Hi Jennifer,
These look so darn tasty and I was drooling over them when I got home yesterday and tried to thaw out! Butter tarts take me back to memories of my grandmother who made the best tarts ever. I just have to have a bite of these so I will take the recipe over to my sister in law’s and we’ll make them for the whole family. Thanks!
Thanks Robyn and sounds like a great plan! And there are snow flakes falling out my window right now.
I bet these are a little like pecan pie but with maple syrup – and that sounds perfect. I am a big fan of nuts and shortbread and I can only imagine how terrific these would be with fresh tapped maple syrup!
Thanks Tricia and yes, very pecan pie-like. The maple syrup filling is so delicious!
Very yummy looking, actually drool-worthy! I’m always a sucker for a shortbread crust and when you add maple and nuts, I’m all in!!
Thanks so much, Chris :)
These squares are so totally up my alley Jennifer! I would not be able to resist a plate of these! Perfect to make for company, so I won’t eat them all myself! (No will power!)
I love your maple recipes, and these squares have my name all over them — that gooey filling looks incredible.
Thanks Sue!
These sound so darn good and I’m trying hard to stay away from sweets. Have a good weekend!
These are darn good, Liz. Sorry! Maybe you could do what I do. Eat one and freeze the rest :)
