Dates Recipe that's a Wedding Cake?
Each time I make these oaty date squares, I ask myself why I don't make them more often. Granny called this date recipe "Matrimonial Cake" and it was my personal favourite of all my childhood baking in Scotland.

It was wonderful to be back in Scotland celebrating my cousin, Lindsay's wedding to Eddie in Edinburgh.
Lindsay is the life and soul of every family party and at Christmas time, before you know it after Auntie Catherine lights up her homemade Figgy Pudding with brandy, there's no snoozing by the fire. You can pretty much guarantee that Lindsay puts you into a team as she's organised party games, quizzes and prizes. Eddie, you're in for a most fun-loving life together and wish you both matrimonial bliss for a long, healthy and happy vie en amoureux.
As they say in Scotland to wish the married couple well, "Lang may yer lum reek" (long may your chimney smoke)!

Back home in France - as the honeymooners had found the sunshine - we were unexpectedly snowed in. For the first time in five years, Paris was briefly coated in a giant duvet of snow and with the girls' lycée closed, it meant I turned to Granny's Black Book of Scottish Recipes for our golden sunshine in the cosy kitchen.
Still in wedding mode, it had to be Matrimonial Cake!

Why is it called Matrimonial Cake?
Goodness knows why the recipe is called "Matrimonial Cake". Do you know of its origins? If you do, then please leave a comment below this post - I'd love to hear from you.
Its name is probably just because it was served at weddings. It's ideal for a winter wedding, as dates are easy to keep in store. My theory is that it's simply so deliciously addictive that it had to be kept for weddings or special occasions.
Already there are many ideas below from you as to why it got its name. Here are some wonderful readers' examples:
- it was a popular budget wedding cake made during the Depression
- like matrimony, you had to mix the rough with the smooth
- the cake was so simple, any newly-wed could make it
- it was a matrimony cake recipe after a lot of dates
- a date between two sheets (oh-là-là !)

Where Do Date Squares Come From?
All I know is that this date square recipe is popular in Canada, with some Canadians mentioning that the recipe originally came from Scotland.
This is when I wish I could have asked Granny tons of questions today, as this recipe probably has a lot more to it than meets the eye. All I know is that before life with Grandpa, she'd left Scotland and lived in Canada for about 3 years with a most adventurous life as nanny to five children of a business tycoon of a canning factory, originally from Kinlochleven in Scotland. Mr & Mrs Stewart loved entertaining and while travelling in their private plane, Granny had full control of their children, taking them on holiday, baking, sewing etc. and keeping up with the glamorous life.

When she baked these date squares with us, who knows what was running in her mind of memories? Questions were taboo back in these days but knowing this now, I'd be dying to know the children's names. Were they named after her own 5 children later: Ronald, Shirley, Irene, June and Catherine?
So, these date squares or Matrimonial Cake looks like it came from her previous life in Canada.
Whatever its origins, this Matrimonial Cake is just as addictive as I remember it. Now my own children ask for this recipe, now that they're away from home.

Matrimonial Cake: Healthy Recipe with Dates and Oats
As Granny's recipe used cups, I've double-checked the quantities to also provide measures in French grams.
As always, I've reduced the sugar to make this a healthy recipe. Oats also provide a good amount of soluble fibre.
Granny mentions using lemon juice so I'm sticking with it. She even added a bit more which made the date paste turn a bit pinkish in colour - so appropriate as a Valentine dessert recipe.
I see in other Canadian recipes that they use orange juice instead plus even some zest but I prefer keeping it simple as I remember it. If you feel some zest coming on, then go for it!

Once the delicious shortbread-like oat crumble is pressed in to the bottom of the tin and spread with the date paste, just drop on the crumble topping. Only gently pat it down so that the effect is a bit crumbly on top.
Granny didn't use much crumble on top - if you like a lot then increase the crumble recipe but the magic is the recipe below. This meant that you could still see the date nectar underneath. The crumble was more of a slightly sparse hint - which is why we craved even more!

Don't have dates for Matrimonial Cake?
No worries if you don't have dates - although it's still best with them. Make a different matrimonial cake with:
- prunes and add some orange zest (I have a prune, orange & Armagnac recipe for macarons in my first book, Mad About Macarons!)
- spread on sweetened chestnut & vanilla paste (Clément Faugier or Sabaton), known as Crème de Marron. See more about chestnuts. Most top patisseries in Paris also sell them in jars.
- no-suet mincemeat - using dates in the ingredients

How Long Do Date Squares Keep?
I can also safely make Granny's Matrimonial Cake and leave it sitting in an airtight box for up to a week.
During winter, I can leave them out of the fridge as it's cool enough but otherwise keep them in the fridge and take them out 30 minutes before eating to enjoy them at their best at room temperature.

Matrimonial Cake (Date Squares)
Equipment
- non-stick baking tin 27x19cm tin (7.5 x 10.5 inches) with lip of at least 3cm (1 inch)
Ingredients
Date Filling
- 255 g (9 oz/2 cups) Pitted dates either in a block or separate in packets
- 110 ml (4 fl oz/½ cup) boiling water
- 1 tablespoon soft light brown sugar (optional)
- 1 lemon juice of lemon only
Oat Shortbread
- 110 g (4 oz/½ cup) butter (unsalted) softened
- 100 g (3.5 oz/½ cup) soft light brown sugar
- 90 g (3 oz/1 cup) porridge oats
- 120 g (4 oz/1 cup) plain flour all-purpose
- 1 teaspoon baking soda
- 1 good pinch salt (fleur de sel)
- ½ teaspoon vanilla extract (or vanilla powder)
Instructions
For the Date Filling:
- In a saucepan, cook together all the ingredients except the lemon juice. Cook gently until soft (about 20 minutes). It's ready when the dates soften into a paste. (If you prefer having a perfectly smooth paste, then blitz it for a few seconds in a food processor.) Set aside to cool then add the lemon juice.
For the Oat Shortbread Crumble:
- Preheat the oven to 180°C/160°C fan/360°F/Gas 4 and grease a baking tin (I use a 27x19cm tin) with either butter or even better, use a non-stick tin.
- Cream the butter and sugar together either by hand using a wooden spoon or better, in a food mixer/processor.
- Add oats, flour, soda and vanilla until well combined.
- Press no more than half of the mixture into the greased baking tin - either with your fingers or using a flat spatula to make the bottom layer even and thin. Spread on the date paste using a spatula and smooth it out until even.
- Top with the oaty shortbread crumbs and gently pat it on top to keep it in place but not too much - it's better to have a crumbly look to the light topping.
- Bake in the oven for about 30 minutes or until the oats are lightly toasted.
- Cool on a wire rack then place in the fridge for about 30 minutes, remove from the tin and cut into squares - or bars, if you prefer.

TIP: Boil the dates in day old coffee instead of water. The coffee takes a lot of the sweetness out of the dates and adds a nice subtle background flavor that goes wonderfully with these squares.
Jill Colonna
Thanks for sharing your tip, Bryan - I love this!
Helen
Sounds like like a good idea to use coffee. I may try it.
The recipe I use came to Canada from Scotland with my greatGrandma. Each generation of daughters has copied her cookbook. I copied Mom’s over 65 years ago.
Jill Colonna
That's so precious, Helen. So glad you're passing it on to your next family generations. Have a delicious 2021!
Kathy
I’ve heard it was called Matrimonial Cake because it was so simple it was the first thing a bride could make
Jill Colonna
Lovely - thanks for that, Kathy x
Patricia
It’s called matrimonial cake because of the smooth base and the rough topping..... you have to take the rough with the smooth!!!
Jill Colonna
Love it! Heard of this one before - sounds like a perfect name for it 🙂 Thanks for popping in.
Laura Dene Mchugh
My Canadian grandma made these. She always said it was called Matrimonial Cake because it was made with dates!
Jill Colonna
That's so lovely! Thanks for popping in and telling us your story, Laura x
Charlotte
My mom told me they were date squares before marriage
Matrimonial soon after
Grumble later
We called it grumble cake
Hahaha
Thx for recipe I'm going to make some grumble
Jill Colonna
Absolutely love this, Charlotte! Too funny, your grumble cake. Thanks for sharing x
Christina Conte
I've seen you sharing this recipe, so how did I miss leaving a comment?! Oh dear, maybe I was traveling? I've got everything to make these, but have had an idea as I have an inordinate number of jars of jam! I'm thinking of replacing the dates with jam? If I make them, will let you know if it works as if I don't start using my jam soon, we'll be in trouble! Thanks for sharing a lovely recipe, Jill!
Jill Colonna
Hehe, replace the dates and it's no longer matrimonial cake 🙂 I know you don't like dates but it's like sticky toffee pudding - it's not really datey as such; it's the consistency that's memorable. By all means on the jam (let's do what we can!) but if you have juicy prunes then I'm sure that would be closer to the real McCoy.
Christina Conte
Well, they're in the oven! Looking and smelling fab!! Thanks, Jill!
Jill Colonna
Well that is brilliant! I thought you didn't like dates, though? 😉
Kirsten
I misplaced Mum's recipe & was happy to find yours. I'm another Canadian who grew up with matrimonial cake as a staple in my lunch. Mum made it quickly with just a touch of lemon juice--no rind or orange juice. No doubt the recipe nanded down from her Scottish ancestors, they came to Ontario from Inverness-shire in 1830.
Jill Colonna
Imagine having this as a staple for lunch? I'm in love! Thanks for popping in and sharing your story. It's incredible the number of Scottish-Canadian connections there are. Have a delicious weekend.
Helen Galbraith
Love Matrimonial Cake. Grew up having it and now almost 80 I still make it. A panic in the oven right now!
I used my Mom’s recipe. She copied her Mother’s cookbook and Grandma had copied her Mother’s. My Great Grandparents came to Canada fro Scotland in about 1865. The cookbook came with them and the Matrimonial Cake recipe was in that book so the recipe goes back that far to Scotland. They came to Quebec and very shortly after that moved to Ontario. My Grandmother left home and came to Saskatchewan. A copy of her Mother’s cookbook came with her. She married my Grandfather in Saskatoon in 1910.
Jill Colonna
Thank you so much for popping in and sharing this lovely family history with us, Helen. How wonderful to have so much knowledge of your own family history between Scotland and Canada. Wishing you a most wonderful Christmas and all the best for a most healthy and delicious 2020!
Sue
Hi Jill. My great-grandmother’s ancestors emigrated from England to Connecticut in the 1600’s, then on to Saskatchewan in the 1800’s. Eventually, my great-grandparents and grandparents moved West to Vancouver, where I was born. When I was growing up, one of our Christmas baking traditions with Grandma and Great-Grandma, was Matrimonial Cake, along with Butter/Currant Tarts, and Date Bread. I am currently visiting my daughter in Pittsburgh, away from my recipes at home in San Diego, and a friend in Alaska remembers Matrimonial Cake from our childhood, and asked for the recipe, so that is what brought me to your website. I’m not sure about the amounts of sugar, and we never used lemon juice or any other flavoring in the filling, but the rest of your recipe looks like what I remember. Last time I made it was probably about 10 years ago. There was an ancestor from Scotland before the English ones, but that’s where the trail stops, so far, on ancestry dot com. I too, wish that I’d asked more questions before it was too late. Also, being an American now, I’d appreciate the measurements in cups. Thank you.
Jill Colonna
Lovely to have you join me here through matrimonial cake, Sue! That's so impressive to be able to go back to the 17th century in your family line-up. I do hope you've got photos too, something that I realise now that's difficult to find. As for measurements, I don't believe in cups, I'm afraid. I do, however, give recipe quantities in ounces for you over the pond as when baking (especially French patisserie like we do here), we use digital scales which gives consistent results each time. I can't encourage you enough to bake using scales by weight. See my article about baking using digital scales, which are inexpensive - and perfect for Christmas!
Have a most lovely, delicious time with your daughter making recipes that rekindles childhood and happy memories. Thanks for popping in to say hello!
Eleanor Charnell
My American mother from Grand Rapids, Michigan, told us that Matrimonial Cake was called this because it was "two crumbs brought together by a date" ! Idea: Uncooked oatmeal porridge. Equal parts rolled oats and cold water. Optional sweetening with honey or brown sugar. ( Suggest 1 cup oats, 1 cup water, 1 teaspoon honey. ) Mix in a tight container, overnight in fridge or cool camping tent or car. . READY TO EAT in 12 hrs. or 24. Regular "slow" rolled oats have more texture and mouth feel. When oats are rolled, they are heat treated enough that they are digestible.without further cooking. Handy to know when hiking or really busy. Nutritious and economical.
Jill Colonna
Love the reason behind the name for Matrimonial Cake, Eleanor. Too funny.
Thanks also for sharing your uncooked porridge for camping or when on the move. Jx
Tina
Hi Jill, my aunt said it was called Matrimonial cake as you had the rough with the smooth.
Jill Colonna
Absolutely LOVE this! Thanks for sharing, Tina. I think we need a dose of matrimonial cake during these strange times at home...
